The way in which ads are traded via programmatic methods has evolved and now there are various mechanisms available such as open auction, guaranteed and private marketplaces. One of the key evolutions in the programmatic trading industry has been header bidding which has impacted the way in which inventory is bought and sold and the auction dynamics.
IAB Europe white paper explores the basics of what header bidding is and how it works; recent header bidding developments; the challenges and opportunities for buy-side and sell-side stakeholders. It also provides guidance on the key considerations and impacts for buy-side and sell-side stakeholders implementing header bidding strategies.

온라인 광고는 현재 인터넷 비즈니스 모델을 가능케하는 핵심 동인이다. 새로운 서비스가 등장하고 시장 규모가 커짐에 따라서 온라인 광고 생태계도 함께 진화하고 여러 기술적 도전이 있다. 지면 중심에서 오디언스 중심으로, 단순 광고 노출과 클릭에서 광고주의 필요를 반영한 다양한 전환으로, 그리고 수의 계약에서 실시간 자동 입찰로 온라인 광고 생태계가 진화하고 있다. 이런 변화의 흐름에서 여러 지면에 접속하는 사용자들의 성향을 즉시 분석해서 가장 적합한 광고를 실시간으로 선택하고 노출하는 것은 기술적으로 매우 어려운 문제다. 본 발표는 카카오의 광고 랭킹에 필요한 데이터와 알고리즘을 간략히 소개한다.

The mobile world is fast changing and filled with many outlandish terms to the uninitiated. Don’t feel intimidated! Here’s a quick glossary guide to some of the most popular terms you may encounter.
Presented at TMKedu by Craig Stein on August 6, 2014
Consumers are now spending more time with digital media than any other channel — even TV -- and advertisers are following suit. This presentation focuses on three key digital tactics: site direct display, digital video, and paid social. Specifically it covers the history of these channels, when and why to use them, how to plan and buy for them, and the tools at our disposal for activating and trafficking the buy.
Header bidding - Everything you need to knowAutomatad Inc.
Header Bidding is an advanced programmatic technique which allows you to call multiple demand partners or bidders to bid on your ad inventory, before sending the ad request to the Ad server.
This increases CPMs and Yield of your inventories. It has been used by 71% of the US publishers and proven method of increasing your Ad revenue by 60%.
In this slide, you'll learn 'What is Header Bidding', 'How header bidding works', the current state of the technology, and more.
At Automatad Inc, we've deployed our 'Header Bidding' solution to 100+ publishers across the globe and seen a drastic increase in the revenue.

Magnite - taking action on identity in europe - april 2021Romain Fonnier
The Identity and 3rd party cookie commotion has reached a critical point in Europe - and recent announcements from Google (and the ensuing industry chatter) have created an atmosphere of fear and confusion within the programmatic ecosystem.
It's time to clear up the confusion and move forward. This webinar aims to:
• Provide context and clarity to the confusion
• Highlight the key areas of focus
• Show publishers the collaborative path forward - timelines and actionable steps
ID5 - the state of digital identity - 2021Romain Fonnier
Dépendre des cohortes et des signaux déterministes n’est pas suffisant pour permettre au secteur de prospérer dans un avenir sans cookies ; le rapport d’ID5 sur l’identité le démontre
Pour son deuxième rapport, le fournisseur de solutions d’identité a sondé le secteur afin d’évaluer l’importance de l’identité dans la publicité numérique et la manière dont les perspectives sur l’identité ont évolué au fil du temps. Le dernier rapport révèle que l’identité est de plus en plus prioritaire dans le paysage de la publicité numérique : 82 % des personnes interrogées ont déclaré qu’elles considéraient l’identification numérique des utilisateurs comme « très importante » pour leur entreprise. L’adoption de solutions d’identité universelle est sur une trajectoire ascendante, 43 % des répondants du secteur déclarant être déjà impliqués avec des fournisseurs d’identité universelle et 43 % supplémentaires déclarant être en phase d’évaluation.

Cette année, le Salon de la Radio a été remplacé par le RadioWeek, qui s'est tenu 100% en ligne durant 5 journées thématiques du 18 au 22 janvier 2021.
A cette occasion, l'IAB France a organisé un webinar autour de l'Audio Programmatique afin de présenter les travaux de la Task Force Audio Digital et les perspectives 2021.
Le barometre du programmatique - IAB France - 2021Romain Fonnier
L'IAB France publie son 1er Baromètre Programmatique. Vendredi 5 Février 2021- L'Interactive Advertising Bureau France (IAB France) crée le 1er Baromètre Programmatique qui présente l’évolution du marché en 2020 (vs 2019) et les niveaux d’investissements programmatiques en France sur l’ensemble des environnements publicitaires excluant les wall garden, le social et le search.
Cette 1e édition du Baromètre Programmatique a été réalisée dans le cadre des travaux de la Task Force Programmatique pilotée par Philippe Framezelle, Directeur de la Régie Adverline et présentée le 4 février lors d’un webinaire.
Destiné à l’ensemble des acteurs de la chaîne de valeur, ce baromètre a pour objectif d’apporter plus d’insights et de lisibilité au marché par un suivi régulier de l’état des achats programmatiques en France.
Les données partagées dans ce baromètre ont fait l’objet d’une analyse approfondie menée par Adomik, technologie d’analyse de la data. Le Baromètre met en avant la répartition des achats programmatiques par format, device, type de deal et offre une vue sur les CPM, les top annonceurs et top bidders. Sur le périmètre mesuré, les investissements 2020 sont en diminution de -4,3% et le CPM moyen en programmatique se situe à 0,96€.
Pour la 1ère fois, le mobile est le device en tête des achats programmatiques.
On constate une chute des CPM lors du premier confinement qui n’a pas été confirmé lors du second avec une remontée des CPM sur le dernier trimestre.
La publicite TV segmentée - IAB France - Octobre 2020Romain Fonnier
L’AF2M, l’IAB France et le SNPTV s’associent pour publier un Guide sur « La publicité segmentée » destiné aux annonceurs
Elaboré par les experts des groupes de travail de l’IAB, de l’AF2M et du SNPTV, ce guide s’adresse à tous les annonceurs désireux de mieux comprendre les spécificités de cette nouvelle opportunité TV.
Les lecteurs y découvriront l’architecture technologique mise en place, ainsi que le calendrier de mise en œuvre jusqu’à fin 2021 avec les différentes étapes successives, les modes de réception compatibles avec ce type de publicité et enfin les échanges nécessaires entre les opérateurs de télécommunication et les éditeurs de chaînes de télévision. Par ailleurs, afin de clarifier et faciliter la compréhension de tous, un glossaire a été élaboré, reprenant les termes utilisés en matière de TV segmentée.
Ce Guide est disponible et téléchargeable dès maintenant sur les sites des 3 associations contributrices.
« Ce Guide a été construit afin d’aider les annonceurs à mieux comprendre la complémentarité entre la TV traditionnelle et la TV segmentée. Il exprime bien les nouvelles possibilités offertes aux marques sachant que les limites actuelles seront levées progressivement pour permettre le développement d’un nouveau marché. ». Isabelle Vignon, Déléguée Générale SNPTV.
« Nous sommes très heureux de nous être associés à l’AF2M et au SNPTV pour publier ce guide qui nous a semblé nécessaire alors que nous sommes au démarrage de la phase de convergence entre Télévision et Digital. Ce n’est que le début d’une nouvelle expérience publicitaire que tous les acteurs de l’adtech suivent avec attention. » Jacques Cazin, CEO Adways et responsable de la Task Force Vidéo & TV segmentée de l’IAB France.
« La Télévision, grâce au Digital et à la forte implication des Opérateurs, va offrir de nouvelles possibilités aux marques pour toucher leurs cibles. Opportunités qui feront naître, à n’en pas douter, de nouvelles approches ou stratégies de communication de la part d’annonceurs, grands ou petits. » Natalie Jouen Arzur, Déléguée Générale de l’AF2M.
Guide cookieless - Quel futur pour le cookie ? - IAB france - 2020Romain Fonnier
L’IAB France publie un guide sur le futur du ciblage sans cookies tiers
Elaboré par les experts du groupe de travail « Identity Cokieless » de l’IAB France, ce guide s’adresse principalement aux acteurs de l’industrie du marketing et de la communication en ligne qui s’interrogent sur l’avenir du cookie tiers et le devenir du ciblage publicitaire. Ce guide à vocation pédagogique s’adresse à un public désireux de mieux comprendre le fonctionnement des cookies, comment ils sont recueillis et activés à des fins de communication en ligne.
Les experts de la Task Force Identity Cookieless ont fait le point sur les solutions aujourd’hui envisagées à date. L’ensemble de ces réflexions est rassemblé dans un guide.
Une architecture claire et simple sous la forme d’intercalaires qui permet au lecteur de trouver rapidement les informations liées à chaque solution.
Augustin Decré, pilote de la Task Force Identity Cookieless et Managing Director Southern Europe d'Index Exchange précise: "Alors que beaucoup d’acteurs de l’industrie évoquent déjà la fin du cookie tiers pour 2022, il n’existe actuellement pas de solution idéale pour remplacer cet identifiant, qui reste, depuis 25 ans, une infrastructure essentielle pour l’ensemble de la publicité digitale. »
A ce jour, des questions subsistent encore, les entreprises de l’industrie restent mobilisées, sur le plan européen et international via le projet REARC de l’IAB, pour apporter de nouvelles solutions viables sur le long terme.
Des mises à jour régulières seront effectuées selon les nouvelles approches envisagées.
Un webinar sur le même thème, a été organisé par l’IAB France le 10 décembre dernier. Plus de 150 participants ont été réunis autour des 10 experts membres et pilotes des groupes de travail de la TF Identity Cookieless afin de présenter les grandes lignes du guide cookieless.

Strategies and Opportunities for a Cookie-less World - Pubmatic - April 2021Romain Fonnier
Publishers and buyers agree: While the future of alternative solutions to the third-party cookie is still uncertain, there is tremendous opportunity for an addressable open internet and addressing the issue is a priority for many in 2021.
With the ad tech industry still evolving around the change in identity resolution, both publishers and buyers are taking stock of what their options are moving forward.
Le guide de la brand safety et brand suitability - SRI - 2021Romain Fonnier
En mars 2020, le marché publicitaire digital s’est resserré : le confinement a provoqué une réduction des campagnes, mais aussi une généralisation des filtres bloquant la publicité dans les contextes liés au Covid19. Cela a eu un impact conséquent sur la monétisation publicitaire des contenus premium. Cet épisode, qui a pénalisé directement les éditeurs et leurs régies, a révélé un grand besoin de clarification et de pédagogie en matière de brand safety. Dans cette perspective, les experts du SRI ont rassemblé leurs connaissances et pratiques du sujet dans un nouveau ‘Pense pas bête’ : le Guide de la brand safety et de la brand suitability.
Face à la dispersion des campagnes digitales, les annonceurs et leurs agences doivent s’assurer que les contextes de diffusion sont appropriés aux marques et que leurs campagnes ne financent pas des contenus universellement jugés indésirables (contenus illégaux, pornographiques ou incitant à la haine par exemple). Si ces pratiques ne sont pas nouvelles, les outils et les technologies de filtrage utilisés se sont récemment multipliés et complexifiés, et leur gestion induit parfois des effets contre-productifs. Les marques, pour ne pas associer associer leurs campagnes à des contenus inappropriés, peuvent actionner ces filtres à différents niveaux de la chaine publicitaire, notamment sur la base de mots clés, appelés aussi blacklists ou blocklists. Mais leur emploi, parfois maladroit, redondant ou excessif, impacte directement les volumes d’inventaires publicitaires disponibles sur les sites et de la même manière, l’efficacité des campagnes.
Aussi, comme il l’a déjà fait avec le programmatique, les cookies ou l’efficacité, le SRI propose dans un nouveau ‘Pense pas Bête’ de considérer cette légitime préoccupation des marques pour en donner une vue d’ensemble claire et pédagogique. Ce document est basé sur des entretiens avec de nombreuses parties prenantes - éditeurs, agences & tech - et réconcilie les visions sell side et buy side. En effet, pour que chacun puisse jouer efficacement son rôle dans la chaîne, il est essentiel de s’accorder sur une vision commune. C’est l’objet de ce guide qui permet de partager des définitions, de clarifier les rôles de chacun, de comprendre le fonctionnement des outils et de rassembler quelques bonnes pratiques et recommandations.

Data Providers & TechnologiesData providers collect, compile and sell (anonymous) data on (online) consumers. The data management platforms manage, protect and collect the data from different online and offline sources and turn it into actionable information that can be used by buyers and sellers.AgenciesAn advertising agency or media agency is a service business dedicated to creating, planning, and handling advertising (and sometimes other forms of promotion) for its clients. An ad agency is independent from the client and provides an outside point of view to the effort of selling the client’s products or services.

Le champ des possibles en matière d’optimisation des
performances susceptibles de rendre les campagnes
de publicité plus efficaces, est pour les annonceurs
comme pour les prestataires très étendu.
Chose inconcevable avec la publicité offline.
Ainsi, afin de pouvoir suivre les statistiques d’une
campagne online, un annonceur va intégrer à ses
liens de redirection des trackings qui permettront par
la suite l’étude des résultats sur un outil d’analyse
approprié et il pourra également arriver que
l’annonceur utilise deux outils d’analyse statistique,
voire, si un prestataire est impliqué dans la gestion
de la campagne, que ce dernier ajoute également son
propre outil d’analyse.
Malheureusement, il est très rare que l’on puisse
coordonner les différents outils de mesure afin de
permettre l’obtention d’informations communes.
De fait, les données varient le plus souvent au niveau
des clics et des impressions. Cela peut être parfois
source de désaccord entre les deux entités que sont
l’annonceur et le prestataire, tous deux impliqués
au même titre dans la campagne publicitaire.
Bien évidemment, force est de constater qu’il n’y a
pas d’outil d’analyse meilleur qu’un autre, et si les
données obtenues diffèrent souvent, c’est d’abord
que les méthodes et les facteurs d’analyse divergent
beaucoup d’un outil à l’autre.
À partir de quand faut-il essayer de comprendre
l’écart de statistiques ? Nous le verrons au travers de
ce document.
L'édition 2019 du Black Friday a été une fois encore le temps fort du secteur Retail
sur la fin d'année, véritable rampe de lancement de la période englobant Noël et
les soldes d'hiver. De plus en plus plébiscité par les marques et les internautes
(62% des internautes profitent du Black Friday selon un sondage BVA de novembre 2019), le Black Friday 2019 s'est distingué avec un démarrage précoce pour
certains marchands, anticipant d'une semaine la date "officielle" de lancement
afin de couper l'herbe sous le pied de la concurrence en proposant des offres très
agressives d'entrée de jeu.
De façon encore plus visible que lors des précédentes éditions, les soldes continuent de perdre en importance au profit du Black Friday, notamment sur les
secteurs de l'Habillement et de la High tech.
Le volume de business généré à l'occasion de ce temps fort en fait un moment clé
dans la stratégie d'affiliation des marchands qui peuvent s'appuyer à cette occasion sur des verticaux puissants et déclencheurs d'achat pour démultiplier leurs
ventes. L'écosystème des Editeurs a été tout particulièrement dynamique cette
année et a fait la part belle à l'innovation en proposant des dispositifs puissants
alliant personnalisation et performances.
Dans la présente étude, vous trouverez une analyse des principaux indicateurs
clés de performance par secteur d'activité ainsi qu'une vision affinée sur les 3
temps forts qui se se sont dégagés du Black Friday 2019: la semaine précédant le
jour J, le week-end du Black Friday et la CyberWeek qui a suivi.

Résultats des sondages IAB / CPA : «Les conséquences économiques de la crise covid-19»
A l’image de nombreux pays à travers le monde adoptant des mesures pour lutter contre la propagation du virus COVID-19 dont le confinement, l’économie française est gravement touchée et le digital ne fait pas exception. De nombreux secteurs ont besoin d’un soutien public pour traverser ces moments difficiles. Les gouvernements prennent des mesures de soutien de l’économie et d’anticipation de la reprise d’activité. Le digital ne doit pas en être exempté.
Dans le cadre de la crise sanitaire que nous traversons (Covid 19), le CPA et l’IAB ont réalisé un sondage auprès de leurs adhérents, afin de comprendre les principales préoccupations de l’industrie et les conséquences économiques de cette crise mondiale. Plus de 100 dirigeants d’entreprises représentatives des acteurs du marketing et de la publicité digitale en France (éditeurs, régies, agences, adtech, etc.) ont répondu au questionnaire entre le 7 et le 27 avril dernier.
Tracking : 7 points à vérifier pour comprendre les écarts statistiquesRomain Fonnier
Les annonceurs sont confrontés à des écarts de comptages croissants entre les technologies qu’ils utilisent dans le cadre de leurs campagnes marketing online. Ces écarts brouillent la mesure et l’analyse des performances des opérations mais posent aussi des soucis de facturation de plus en plus fréquents. Afin d’aider tous les acteurs de la chaine marketing digital à mieux cerner les raisons qui sont à l’origine de ces écarts et de leur donner les conseils de première urgence pour les réduire, nous, membres du Collège Technologie du CPA, avons rédigé ces fiches. Elles ont pour but de contribuer à faciliter la compréhension de notre industrie et, en expliquant les phénomènes, de poser des bases permettant à tous d’avoir un repère commun.

Attitudes to Programmatic Advertising Report 2019
IAB Europe’s annual Attitudes to Programmatic Advertising Report is a comprehensive analysis of the European programmatic landscape, covering strategies and adoption trends, drivers of and barriers to growth, and forecasts for the future for 31 markets. The study, now in its fifth year, was developed by the IAB Europe Programmatic Trading Committee. The key findings of the 2019 study include:
There is a continued push for a quality and safe advertising environment
Ads.txt is well established amongst publishers but awareness and adoption on the buy-side is low
Talent and skills remain a barrier to investment
Supply chain transparency is still an issue
The number of advertisers with in-house operations for programmatic is now higher than the number that outsource to an agency
Programmatic continues to be a catalyst for delivering brand campaigns at scale
In light of GDPR, stakeholders are looking to use more first party data, private marketplaces and contextual targeting

1. INTRODUCTION
Half of European display ad revenue is traded programmatically and
programmatic advertising has reached a market value of more than €8bn.
Programmatic is now a key imperative for advertisers, agencies and
publishers alike. The way in which ads are traded via programmatic methods
has evolved with various mechanisms now available such as open auction,
guaranteed and private marketplaces. One of the key evolutions in the
programmatic trading industry has been header bidding which has impacted
the way in which inventory is bought and sold and the auction
dynamics. This white paper explores header bidding including: the basics of
what it is and how it works; recent header bidding developments; the
challenges and opportunities for buy-side and sell-side stakeholders. It also
provides guidance on the key considerations and impacts for buy-side and
sell-side stakeholders implementing header bidding strategies.

2. WHAT IS HEADER BIDDING?
Header bidding is a methodology that allows a standard ad server to
optimise inventory delivery across multiple demand sources by offering the
same available impression to all demand sources in parallel instead of one
after another. This process is relatively new.
A basic principle of ad serving is that ad servers are built to manage single
campaigns and optimise delivery in order to ensure each campaign fulfils
the delivery goal within the defined runtime. Programmatic advertising or
real-time bidding (RTB) technologies such as supply side platforms (SSP)
follow a completely different logic as they are not necessarily built to
optimise single campaigns but to create competition between multiple
buyers for each single impression using an auction mechanism. The
optimisation is first and foremost price based.
5. Header Bidding and Auction Dynamics White Paper
5
On the buy-side, campaigns are optimised by the buyers using demand side
platforms (DSP) that correspond with the SSPs via an API. Header bidding
enables a bridge to be built between both logics.
Header bidding is mostly used where holistic yield optimisation is missing -
either across direct booked campaigns (IO) and RTB based ad delivery or
across multiple SSPs. In an ideal world, the primary ad technology platform
would provide its publisher clients with a true server-side holistic view across
all demand partners with every buying technology integrated via an API
using the OpenRTB protocol. But reality seems far away from this. Many
agencies and ad networks are still buying based on tags instead of using RTB.
Most standard ad serving technologies can only manage different demand
sources in a waterfall setup which makes profound yield optimisation
impossible.
Especially in display advertising, many publishers are using multiple SSPs to
spread their offer to as many potential buyers as possible. To avoid
waterfalls, header bidding is used to optimise across the SSPs and maximise
yield.

Example of an ad serving setup without header bidding
(waterfall example)
The order of demand sources is handled via priority settings, waterfalls (via
pass-backing) or a combination of both.
Ad placement tag or video player SDK calls the ad server
Direct Sold campaigns usually run first (as delivery is
guaranteed)
Unsold inventory gets redirected to SSP 1
Redirect to other demand source (e.g. ad
network)
Redirect to SSP 2

2.1 How does Header Bidding Work?
Header bidding requires Javascript (JS) execution and can therefore only live
in HTML enabled desktop or mobile environments. As final ad delivery is
served via the primary ad server, a publisher must setup a campaign line
item per demand partner per potential clearing price. This enables standard
ad server reporting to be able to give an overview of programmatic revenues
generated on external platforms.
The bids need to be standardised as different partners could be
using different formats. To date there is no central standardisation in place
for header bidding like there is for RTB with the OpenRTB protocol.
Therefore, the bid-responses need to be converted into the correct ad-call
syntax of the publisher ad server. This is done via a JS based logic called a
header wrapper which has to be implemented into the source of a
publisher’s web page. The JS logic conducts the translation between
different bid-response-formats and different ad systems a publisher might
use. For the necessary header wrapper, there are various solutions available.
The most prominent open source solutions are prebid and pubfood, however
pubfood doesn’t support video at the current time.
9. Header Bidding and Auction Dynamics White Paper

The following are mandatory parameters to be transmitted from the header
information collected by the header wrapper and transferred by the header
tag:
▶ (Ad server-) Publisher-ID
▶ (Ad server-) Site-ID
▶ Ad format
▶ Placement width and height
▶ Callback name
▶ Optional parameters:
▶ Max duration of a spot (for video)
▶ Floorprice
2.2 Benefits of Header Bidding
Instead of having an unknown place in a waterfall or priority setting within a
publisher’s ad server, each demand partner is offered the same available
impression(s) and therefore has the chance to see the full audience and
reach of the supply partner. On this basis, the publisher is likely to receive
significantly more bids for each impression offered. The final auction can
happen within a publisher ad server that is normally not designed for this
purpose.
As a result, buyers have increased access to the inventory they may be
looking for and the publishers can further optimise their yield. The
opportunities of header bidding are further explored in section 3.
10. Header Bidding and Auction Dynamics White Paper

2.3 Challenges of Header Bidding
Integrating multiple demand partners on the browser side increases
latencies. The time it takes to call all the demand partners via header
bidding is in addition to the ad server ad call and delivery process. Each and
every demand partner can potentially add a pixel to the user client and
combine the data with reach and contextual information – even when not
buying the impression. The ad operations process to book hundreds or more
line items per demand partner to reflect price buckets can be time
consuming and resource-heavy.
Within header bidding, only first-price auction or fixed CPM is supported as
the ad server can’t determine a second highest bid. This conflicts with the
established RTB models which are based on second price auction. The
challenges of header bidding are further explored in section 3.
GDPR has brought, and the future ePrivacy regulation, will bring further
challanges to header bidding. If a publisher has integrated a Consent
Management Platform (CMP) to fetch an encoded string representing the
user’s consent choices for data processing, the CMP has to be supported by
the header bidding API. This requires a specific module to be added to the
code that fetches the consent information from the CMP and incorporates
this into the auction objects shared with the SSPs or other demand partners.
11. Header Bidding and Auction Dynamics White Paper
11
Supporting the CMP is becoming more importance as SSPs will soon have to
provide this string in their bid requests to the DSPs.
To date, there is no market standard for the technical header bidding
support for CMPs but some header bidding solutions such as prebid provide
basic documentation on the concept.
2.4 Further Use Cases
Holistic delivery across ad placements and ad types
Programmatic demand technologies (and businesses) often specialise in
certain media types, such as standard display, video, rich media or native
ads etc. Consequently, so do SSPs.
If publishers want to build holistic ad delivery on the same placements but
with different ad types (e.g. out-stream video vs. rich media in-page), they
often have no choice but to use different SSPs to get the highest ad quality
and the highest programmatic yield. As explained above, header bidding can
provide a holistic auction across these multiple SSPs.
Agency marketplace
Agency networks have often tried to find a way to move closer to a
publisher’s website, player or app in order to have better view of available
ad inventory.
12. Header Bidding and Auction Dynamics White Paper
12
However, as usually only one SDK or ad server tag is integrated into the
browser directly (the one from the sales house or the publisher ad server),
agencies have found it difficult to get to this setup with their own technology
and were therefore dependent on the ad calls from the publisher ad platform
(or bid requests from publisher SSPs) that are out of their control.
Since header bidding provides the option to have multiple platforms bidding
into the same placement in parallel, some agency networks or trading desks
have been able to host their own marketplace on a given SSP, manage the
bought inventory centrally and sell it to the agencies in their network. This
can provide the agencies within this network higher transparency and better
optimisation capabilities as they would no longer buy single inventory deals
from publishers but from a trading desk that belongs to the same group.

3. THE EVOLUTION OF HEADER
BIDDING AND AUCTION DYNAMICS
The initial role of supply side platforms (SSP) was to aggregate demand for a
publisher by integrating with relevant demand partners (DSPs). At the start,
only one SSP was needed to accomplish this goal. In this environment,
buyers lacked concrete insights into what a fair price might be. To solve this,
second-price auctions were adopted as an industry standard as they gave
buyers an incentive and peace of mind to bid based on the value they
attached to the impression(s). The publisher created a set floor price and the
middle ground / ideal price was then established between the first and
second-price bids.
But, with time and the evolution of the industry, the number of SSPs and
DSPs grew significantly. Publishers then needed multiple SSPs, all of which
had to be integrated, in order to access total demand from the buy-side.
14. Header Bidding and Auction Dynamics White Paper
14
The solution to this was the introduction of “waterfalls”, a cascading series
of SSP calls that solved the problem of multiple SSPs but led to a host of
secondary issues. The prioritisation of demand partners based on historic
pricing and static linear rules created an inefficient marketplace.
Eliminating waterfalls and their added complexity and related issues was
one of the leading reasons for the emergence of header bidding solutions.
The waterfalls created latency while failing to give publishers the very thing
they’d initially been implemented to do i.e. delivery of the best single
impression value. Header bidding provided a mechanism for publishers to
hold a unified auction upstream from the ad server. By making parallel calls
to programmatic demand partners within the header of a page, publishers
are able to access real-time pricing data on an impression-by-impression
level. This technique allows publishers to increase yield by leveraging the
dynamics of real-time bidding to inform ad serving decisions. Soon, header
bidding evolved from a tactic used by tech-savvy publishers to capture
incremental spend to becoming a central component of most publishers’
programmatic strategies.
With header bidding, a publisher is able to receive winning bids from
multiple SSPs compared in parallel and to decide on the overall best price
across all of them. But for every single SSP (and all integrated DSPs) it means
that they suddenly have to handle an increased amount of requests without
an actual promise to monetise the impression by rendering the ad.
15. Header Bidding and Auction Dynamics White Paper
15
Apart from impressions dedicated to guaranteed delivery that, within a
traditional publisher ad server, comes before non-guaranteed or price
priority (and header bidding demand as well), there is also competition
between SSPs in choosing the best clearing price.
Even with different floor prices, soft floor prices and different methods
applied in order to pick the clearing price, the bid prices passed from the SSP
to header bidding for the final bid price isn’t necessarily the value the
advertiser was willing to pay. This potentially means less revenue for the
publisher and a decrease in an advertiser’s ability to win the impressions
they want.
Header bidding has also introduced some operational and technical
challenges. The integration process has been cumbersome; each new tag
required support from publishers’ engineering teams and, with limited
reporting infrastructure, ad operations teams lost the ability to manually
intervene to exchange partners’ performance. Wrapper solutions emerged in
order to solve these problems. A wrapper acts as a container of all the
header tags that the publisher would like to use, making it easier for
publishers to complete integrations. Some wrappers are based on open
source technology like prebid and pubfood and others are based on
proprietary technology.

3.1 Recent Developments
Server-side header bidding
Significant strides have been made as header bidding has matured over the
past few years. Among the most prominent has been the transition to server-
to-server (S2S) header bidding and wrappers as a solution to better manage
latency. S2S header bidding moves most of the execution from the browser
to a technology provider’s infrastructure, making the page lighter so content
and ads load faster, resulting in less impact on user experience. S2S also
allows for faster response times between demand side platforms (DSP) and
sell side platforms (SSP).
17. Header Bidding and Auction Dynamics White Paper
17
S2S header bidding is still in early stages but holds a lot of potential to help
publishers achieve increased speed and monetisation. For a variety of
reasons, such as the availability of demand or the complexity of managing
user syncs across demand partners, some publishers are not ready to move
completely to S2S. These publishers can leverage a hybrid solution, which
combines client-side and server-side header bidding, thus improving access
to demand and improving monetisation.
Move to first-price
Changes driven largely by the proliferation of header bidding have impacted
how auctions operate. Inconsistencies across header bidding auctions and
lack of transparency into how each auction operates has created an
environment where buyers do not have visibility into whether auctions are
being closed at first or second-price. This makes it difficult for buyers to set
bidding strategies that allow them to simultaneously maintain access to
impressions and consistently increase spend. To address these concerns,
many SSPs and DSPs have transitioned to submitting first-price bids in
header bidding transactions. To support this shift, SSPs and DSPs leverage
the IAB Tech Lab OpenRTB 2.3 and 2.5 specs and pass the auction type and
destination flags (“at=1”, “fd=0/1”) in the bidstream. These parameters
empower DSPs to set the appropriate bidding strategies based on the type of
auction they are participating in.
18. Header Bidding and Auction Dynamics White Paper
18
Mobile app header bidding
App publishers today largely rely on a mediation process of multiple
exchanges in a waterfall and multiple software development kits (SDK) for
monetisation. Multiple SDKs make the app heavier and impact performance,
and installing them can take up limited engineering resources. Additionally,
adding a new demand partner directly in an app requires the developer to
update the app on Google Play or the Apple App Store, which requires a non-
trivial release process.
Server-side in-app header bidding (also known as parallel bidding) leverages
a lightweight and flexible code that requires a one-time installation in the
app. Any subsequent exchange / SSP adaptors are integrated within the
server, which makes a call to the respective exchange. This methodology has
several benefits. It simplifies the integration of new demand sources by
reducing the technical complexity managed within the app, and also speeds
up the activation and deactivation of demand sources. As a result, publishers
do not have to wait for weeks to modify their app and get Google Play or the
Apple App Store to approve the modifications. Fewer changes to the ad tech
dimensions of apps allow publishers to spend more time on their core
features, and limit the risks introduced by frequent release processes.
Latency is also reduced because the technology provider’s infrastructure,
rather than the handheld device, handles the majority of the ad call process.
The publisher does not need to rely on the computational power of the
user’s device, resulting in better latency controls, potentially more
successful bid responses, improved auction dynamics and better
monetisation.

4. CHALLENGES AND
OPPORTUNITIES
4.1 Buy-Side Challenges
The biggest challenge that header bidding has introduced to the buy-side is
finding the new equilibrium price. Now that the same impression
reaches the bidders from multiple sources, it has become crucial for the
buy-side platforms to be aware of the bid request context, otherwise bids
submitted to seemingly independent auctions actually compete with each
other thus raising the auction clearing price. At the same time, buyers that
are used to second-price auctions as the de-facto standard of auction
mechanics often treated the bid prices in fixed-bidding scenarios as a value
indicator, rather than actual CPM they’re willing to pay. Initiatives have been
undertaken to improve this situation, however the adoption of transaction ID
(part of OpenRTB) is still low which means it’s in the hands of DSPs to protect
their customers from potentially overpaying.
20. Header Bidding and Auction Dynamics White Paper
20
Solutions vary from allowing the end buyers to differentiate the bid prices for
first and second-price auctions to solving the problem algorithmically
without the user involvement. Yet, the most complex problem requires
further investment, as probabilistic detection of bid requests sent by various
SSPs but originating from the same ad placement, while the industry
waits for broader adoption of transaction ID.
Investments needed on the buy-side are not limited to algorithms, though.
As the adoption of header bidding is constantly growing, so does the sheer
volume of bid requests that is sent to the bidders for evaluation.
Accommodating this extra work load translates to direct investment in
technical infrastructure expansion as well as implementing smarter
and more efficient throttling solutions that previously existed
predominantly on the sell-side.
The proliferation of header bidding resulted in rising inventory processing
costs for DSPs, as they now receive impressions from multiple SSPs, all
bidding into a publisher’s wrapper solution. The infrastructure requirements
needed to process this influx of impressions, measured in queries per second
(QPS) has become a major challenge for buyers. It is necessary for DSPs to
pre-filter the inventory they don’t want to bid on. Historically this was done
via manual optimisation revolving around broad and somewhat static
constructs such as geography, platform, publisher, etc.
21. Header Bidding and Auction Dynamics White Paper
21
4.2 Buy-Side Opportunities
The biggest benefit or opportunity of header bidding for buyers is the
increased transparency into supply-side configurations. Getting the bid
requests from all involved SSPs simultaneously, especially where ads.txt is
implemented, allows optimised bidding, be it optimisation for cost
efficiency, end-client preference or shortest path to supply. Knowing all the
SSPs involved allows the buyers to detect the intermediary tech fee levels.
Further, knowing that the winning bid equals the final settlement price in the
first-price auction allows the buy-side algorithms to predict the optimal bid
prices much better thus maximising buying efficiency. At the same time, the
ability to directly compete with guaranteed campaigns, enables previously
locked down premium-tier inventory to become available in programmatic
trading.
The addition of premium inventory and end-price composition transparency
have increased the level of trust buyers have in programmatic as
workarounds previously used for for second price auction “fixing” have
become irrelevant.
22. Header Bidding and Auction Dynamics White Paper
22
These include:
▶ Modified clearing prices, where the price is chosen in-between first and
second highest prices
▶ Bid price reductions, where the winning price is a pre-defined fraction of
highest bid price
▶ Intelligent optimisations of floor or soft floor prices to be set as close to
the highest bid as possible before the bid requests are sent out to DSPs.
Supply path optimisation (SPO) provides an opportunity for buyers to
safeguard against the infrastructure risks that have arisen with header
bidding. SPO is a broad array of algorithmic and manual tactics covering the
entire supply chain, from publisher to advertiser. Buying through optimised
supply integrations enables buyers to effectively manage QPS (queries per
second), providing advertisers with improvements in the efficiency and
effectiveness of their media spend.
Header bidding also allows buyers to compete for programmatic ad
inventory on an even playing field and provides them with more data to help
inform forecasting and their bid strategy. When waterfall setups were still
the primary implementation for publishers, it was challenging for anyone on
the buy-side (including advertisers) to know exactly how they were
competing and buyers were at the mercy of the waterfall and the order
publishers had chosen to arrange their supply side partners (SSP) in the ad
stack. That hierarchy was usually based on an SSPs historical average CPM,
and not a real-time bid.
23. Header Bidding and Auction Dynamics White Paper
23
This methodology didn’t allow the highest bidder to win outright, because
each bid was considered one after the other in the SSP’s predetermined
order. This approach forced publishers to leave money on the table, and
took media away from buyers whose bids weren’t always being seen, even
when they were the highest bidder. Publishers and exchanges each had
multiple tiers, and private marketplaces (PMPs) were used in different ways
across publishers and technology providers. With header bidding,
advertisers can compete in a clearer unified auction, and generally have the
opportunity to compete for every impression on an equal footing. Buyers can
see and bid on more inventory than ever before, allowing them to better
qualify how they are competing in the auction and adjust their bid strategy
for an optimal win rate. This also helps from a media planning perspective.
Over the next 12 to 24 months, buyers may begin to further realise the
effects header bidding has on their strategies. As the access point to
inventory becomes more clear, fair and organised, economics and logic will
start to prevail. This means that all buyers should compete equally on price
unless a guarantee (hard or soft) is present. As a result, large buyers could
start figuring out ways to scale guaranteed buys where it makes sense to
obtain advantage for their scale.
Further, buyers will realise that header bidding doesn’t necessarily mean
equal priority. Programmatic buyers generally still compete below direct,
but header bidding does make prioritising programmatic buys more
seamless.
24. Header Bidding and Auction Dynamics White Paper
24
As a result, programmatic buyers will likely begin requesting prioritised
access. Lastly, buyers should see a meaningful reduction in ad fraud,
especially domain spoofing, since header bidding allows for a simplified path
to supply.
4.3 Publisher Challenges
The rationale as to why publishers should use header bidding is quite
straightforward. Adding demand to existing supply will help to increase the
value of their inventory. However, as client-side header bidding has seen
widespread adoption, a common publisher concern is page latency and its
impact on user experience. As client-side solutions require the calls to be
made from the user’s browser, a publisher must continually optimise page-
load performance as new header bidder adaptors are integrated. If a
publisher wants to add more bidders to its header bidding setup without
impacting the page latency the natural choice would be to either go with a
server-side wrapper or a hybrid approach where some bidders are integrated
client-side and some server-side. However, many are finding that the
industry is still grappling with cookie or user match rates on the server side.
Technology companies are still in the early stages of creating cross-device
maps and data consortia to help address this problem; as a result, publishers
will likely see a decline in match rates (and therefore buyer interest) when
moving to a S2S environment. Nevertheless, the Header Bidding Industry
Index (HBIX) reported that the usage of both, server-side wrappers and
hybrid solutions have increased in the US between January and June 2018.
25. Header Bidding and Auction Dynamics White Paper
25
When looking in-depth at each step of the header bidding process from the
moment a user enters the website to when the ad is served publishers will
realise there are a number of potential indiscretions. To start at the
beginning, bid requests are being sent to the publishers’ header bidding
partners asynchronously but in the order specified by the publisher. That
means the bidders in the bottom of the list will have less time to respond
and are at greater risk of reaching timeout than the first, and they do not
want to increase the timeout because that will slow down the website. When
all the bidders do respond there is no guarantee that they all respond with
comparable bids as some may respond with a net bid and some with a gross
bid. Bidders might use different auction dynamics, first-price auctions or
second-price auctions. Also, the currency may vary depending on platform
and publisher settings. All of these challenges occur before the winning bid is
passed into the ad server where even more challenges are to be tackled.
All of the above is fairly easy to address. However, one of the key challenges
publishers face when starting to implement and use header bidding is when
they create multiple channels for buyers to access the same inventory. It is
common for buyers to be active on several ad exchanges simultaneously and
if a publisher sells its inventory through multiple SSPs there is a risk that
buyers end up bidding against themselves. Although it will most likely result
in revenue uplift short term, it can harm the relationship between buyers and
sellers in the long term. Since it may have a negative impact on the buyers
spend they will most likely address the problem by introducing new
technologies such as supply path optimisation (SPO) algorithms.
26. Header Bidding and Auction Dynamics White Paper
26
This could mean that header bidding would, on the one hand, give
publishers the opportunity to access more buyers but, on the other hand,
buyers could also utilise the technology to find more cost efficient paths to
access inventory which may be less profitable for the publisher.
4.4 Publisher Opportunities
As previously mentioned, one of the key benefits and opportunities of header
bidding for publishers is that it allows them to access a much wider range of
buyers across multiple demand sources. As obvious as it may sound,
implementing multiple demand sources historically meant publishers had to
design a waterfall structure based on predicted eCPM from each ad
exchange or network - something that a lot of publishers still do. The best
way to mitigate the aforementioned page latency effects is by shifting the ad
call to each partner from the browser itself to an offline server with S2S
header bidding. By doing so, publishers can add as many partners as they
like without increasing latency with each incremental partner. And by
leveraging hybrid wrappers, publishers can test the impact of moving
demand partners from the browser to the server and make adjustments as
measured by performance.
Some of the latest developments of header bidding include the ability to
serve video or native ads as well as standard display banners. This of course
depends on which wrapper the ad server and publisher use but it opens up
great opportunities to maximise revenue for each impression and ad format.
27. Header Bidding and Auction Dynamics White Paper
27
There are various video platforms that generate high quality video ads with
desirable CPMs just as there are various native platforms that generate high
quality native ads with desirable CPMs as well. Header bidding gives
publishers the opportunity to combine those, along with other bidders, into
a unified auction, to achieve high demand for each ad impression.
Consolidating demand of each source and ad format into a single auction
truly enables publishers to have a holistic yield approach since it allows
them to remove not only waterfall layers vertically, but also ad format silos
horizontally.
Header bidding is constantly evolving. Different type of wrappers, ad
formats, client-side vs server-side, in-app header bidding and analytics
adaptors are just some terminologies that publishers should get familiar
with before deciding on a header bidding strategy. Once a strategy has been
developed, the work of technical implementation for both ad ops and
engineers can begin. That being said, if a publisher wants to include header
bidding in their monetisation strategy, they need to invest in both
knowledge and engineering and operation resources and maintenance.

5. KEY CONSIDERATIONS FOR A
HEADER BIDDIG STRATEGY
5.1 Considerations and Impacts for Buy-Side
Stakeholders
While header bidding has improved buyers’ competitiveness in the auction,
there are a few important factors that should be considered when
implementing a header bidding strategy and selecting an exchange partner
as outlined below.
Supply
To make the most out of their budget and ensure brand safety, buyers
should ask their exchanges about their direct publisher relationships and
what unique supply offers they have in comparison with other exchanges.
29. Header Bidding and Auction Dynamics White Paper
29
Fees
Buyers should insist on putting payment terms in writing to ensure
transparency in their partners’ fee structure.
Infrastructure
When evaluating exchanges, buyers need to evaluate the speed and buying
efficiency of their infrastructure. These are major factors in ensuring they can
create the best ad experience for users, and increase the impact of media
spend.
Clean inventory
Brand safety is now more important than ever before. To ensure a controlled
environment, buyers should also make sure they are partnering with
exchanges that have a thorough ad quality and verification process. Ensuring
every partner in the supply chain is taking advantage of initiatives such as
ads.txt also plays a key role in safeguarding clean inventory.
Publisher relationships
While header bidding makes it easier for buyers to purchase inventory via
programmatic trading, publisher relationships are still an integral part of
media buying. Buyers should consider an exchange partner who facilitates
relationships with publishers for private marketplace (PMP) creation and to
facilitate custom media solutions.
30. Header Bidding and Auction Dynamics White Paper
30
Be selective
One potential drawback of header bidding for buyers is that a single
impression may pass through several different exchanges multiple times,
which can cost buyers money and response time. The solution to this is to be
selective about which exchanges a buyer works with, narrowing it down to
only trusted partners who provide unique value.
Based on the above, there are some key questions that buyers can ask of
their partners, these are listed on the following page.
31. Header Bidding and Auction Dynamics White Paper
31
Key questions for buyers
▶ Does the DSP support ads.txt and what level of support is offered?
▶ Does the DSP allow differentiation between direct sellers and re-sellers
when defining supply targeting rules?
▶ Has the DSP implemented support for transaction ID and final decision
flags? If so, with which supply-side platforms?
▶ Has the DSP updated its programmatic optimisation algorithms with first
price auctions in mind? If so, what are the partner’s recommendations for
fixed-bid CPM strategies?
▶ How does the DSP handle mixed auction types (i.e. when a single
campaign targets supply sold via both first and second price auctions), is
this automated or left to the programmatic specialists to solve?
▶ Has the DSP implemented supply path optimisation? If so, what
specifically gets optimised and are different commercial terms taken into
account?
To further enhance transparency, stakeholders can use the IAB Europe
Transparency Guide which provides a set of questions related to cost,
inventory source that can be asked at any point in the supply chain.

5.2 Considerations and Impacts for Publishers
A number of header bidding opportunities and challenges have already been
highlighted for publishers (see section 3). Which wrapper to choose, whether
to have a server-side, client-side or hybrid solution are things that publishers
must think about before going live with header bidding but apart from that
there are a number of things that are important to consider as outlined
below.
Demand partner variety
Header bidding can enable publishers to expand the number of buyers it can
access and this is what publishers should strive for when evaluating which
partners to include. The common pitfall which has already been mentioned
is that publishers tend to add multiple channels for the same buyers which
could have a negative impact on revenues long term. The goal in terms of
demand partners should be to maximise reach and if a publisher wants to
get the most out of the technology they should ensure that advertisers only
can access their inventory through a single demand source. Otherwise there
is a risk they end up bidding against themselves.
Resources and support
When implementing a header bidding strategy, it’s important for a publisher
to consider the internal resources and header bidding expertise they have
available to oversee the initiative.
33. Header Bidding and Auction Dynamics White Paper
33
If a publisher has tech resources to spare and the in-house time and
expertise to implement, augment and optimise, they can consider an open
source header bidding partner. If they don’t have resources to dedicate to
the implementation, analysis and performance of their header bidder, they
could consider a managed service.
Auction dynamics
Nailing the auction dynamic is crucial in order for publishers to get the
highest bid from all the header bidding partners as well as making it
transparent for the buyers. Bidders have increasingly changed their auction
mechanics from second-price auction to first-price auction either by default,
or by publisher choice. One reason behind this is to increase the
transparency for both buyers and sellers.
The image below illustrates how the winning bid can differ between using
first-price auction and second-price auction mechanics. The winning bid in a
second-price auction is actually the fourth highest bid plus one cent.
Header
Bidding
Wrapper
Bidder 1
Bidder 2
Bidder 3
Highest bid €5.00
Second highest bid €1.00
Highest bid €2.00
Second highest bid €1.50
Highest bid €3.00
Second highest bid €1.00
Winning bid
First price auction:
€5.00 – the highest
big among all buyers
Second price
auction:
€1.51 – the fourth
highest bid
34. Header Bidding and Auction Dynamics White Paper
34
Not only does second-price auction result in lower yield for the publisher but
it also makes the auction logic unpredictable for buyers.
Auction dynamic consistency
The beauty of header bidding is that the publishers can integrate additional
demand sources and still follow the standard rules of programmatic where
the highest bidding buyer wins. To do so, publishers must ensure that
auction dynamics are consistent across all demand sources but also that the
setup in the ad server puts header bidding demand on the same
hierarchy. This will benefit the publisher in terms of maximising revenues
but also the buy-side as they will not be forced into certain sales channels
due to demand hierarchy reasons.
Yield optimisation
Consolidating demand across both banner, native and video formats is
something that can enable publishers to achieve true holistic yield. Unifying
demand across all ad formats is something that many SSPs master already
but the potential with header bidding in terms of inventory optimisation is
that niche video ad platforms and native ad platforms can compete along
with the publishers’ other demand sources for every single impression. The
publisher gains full control and can offer all impressions to all partners at the
same time, and let the header bidding auction decide the winner, and pass it
to the ad server to be served on the site.
35. Header Bidding and Auction Dynamics White Paper
35
To optimise the setup and perform yield management there is a need to
have full insight into the auction dynamic, this can be done by adding third
party reporting into the header bidding solution, to gain insight in the
partners and their performance. By looking into bid rates, responses,
timeouts, price and win rates, the publisher will be able to adjust the setup
based on valid statistics.
Choosing a solution
When deciding on a solution, it’s important to make sure, that all needs in
the solution design are covered. The ad server still makes the final decision
on the delivery, and there needs to be a smooth connection between the
header bidding solution and the ad server.
An analysis of the required resources for the implementation must be
undertaken, for example should it be a standard solution or is there a need
for custom solution to fulfil the needs.
There are some key questions that publishers can ask to help with deciding
which solution to choose, these are listed on the following page.
36. Header Bidding and Auction Dynamics White Paper
36
Key questions for publishers
▶ Improving monetisation: Does the wrapper offer access to a broad set of
exchange partners, SSPs, unique demand, and support for PMP? A sound
wrapper solution must provide access to the right kind of demand for the
publisher’s needs. This includes access by inventory type (desktop, tablet,
mobile), content type and audience composition.
▶ Accommodating hybrid models: Can the wrapper manage both client-
side and server-side header bidding in one solution? Publishers need the
flexibility to have both options to maximise the number of partners they
can work with and easily manage performance issues. Otherwise, they
may be creating new complications by running multiple wrapper solutions
simultaneously, just as they have been doing with multiple header
bidders.
▶ Simplifying operations: Is there an intuitive user interface for easily
configuring and optimising demand partners without development work
and code pushes? Does the wrapper offer dedicated account and technical
support teams? Managing a wrapper must enable agile action. Publishers
don’t want to have to send a job ticket or an email to schedule work, when
they can do it more effectively and efficiently.
37. Header Bidding and Auction Dynamics White Paper
37
Key questions for publishers
▶ Robust reporting and analytics: Is there built-in, centralised reporting
functionality for all demand partners with actionable insights such as
latency, bid activity and revenue reports? Publishers should look for
solutions with the ability to provide timely, unified and robust reporting
and analytics. They must be able to easily understand what is happening
with the business and use that information to make smart optimisation
choices. It’s especially vital that all the data live in one place, with simple
access. Publisher’s don’t want to have to wait for a report with a two-day
lag when their buyers are working in real-time.
▶ Transparency: Does the wrapper offer an open infrastructure to increase
transparency, independence, scalability and the critical ability to run a fair
auction based on publishers’ defined rules? Is it based on a standardised
and open source technology like prebid? In order to drive the most
revenue and have a clear understanding of their header bidder, publishers
need to select a wrapper partner that can prove their transparency. This
transparency should be evident in all aspects of their business – including
clear fee structures disclosed in contracts, auditable logs, clear auction
dynamics and handling of multiple header bidders.
▶ Fees: Are the fees clearly outlined? When choosing a header bidding
partner, publishers should make sure that there are no hidden fees. There
should be no surprise costs as the technology develops and they bring new
support features to market, such as reporting or identity.
38. Header Bidding and Auction Dynamics White Paper
38
Key questions for publishers
▶ Fairness: Does the wrapper evaluate each bid based on equal criteria?
There are many factors to consider when a header bidder evaluates a bid,
including:
o Are all bidders competing based on net, not gross, prices?
o Is everyone leveraging a similar auction strategy? (for instance, first
price or second price auctions.) If not, is fair competition being
enabled?
o Is everyone on the same time out? This is a significant factor in
balancing revenue and user experience.
o Are there any header bidders directly on the page? If so, they may
have a huge advantage in escaping timeouts, a competitive edge in
pricing and potentially allowing less time for other bidders.
o Are all bidders competing on an equal level in the ad server?
▶ Future-looking: A header bidding provider should be working to evolve
and integrate new technologies that will increase the value of
programmatic impressions, such as a robust identity strategy for
increasing user matching.
39. Header Bidding and Auction Dynamics White Paper
39
Publishers should insist on an open and transparent marketplace to ensure
they and their SSPs can have confidence in the fairness of the auction. There
are also meaningful operational and technical benefits to a solution that is
open source. Open source wrappers make it easier for publishers and
monetisation partners to proactively identify and correct issues. They also
allow for shared best practices for set up and troubleshooting, providing for
rapid resolutions when issues do arise.

6. SUMMARY AND THE FUTURE OF
PROGRAMMATIC AUCTION
DYNAMICS
While server-side header bidding development has moved forward, the
adoption is still slow. It is, however, seen as a unified way for header bidding
across different formats and screens, thus publishers will soon find it easier
to apply similar techniques across all of their assets including mobile in-app,
native advertising, accelerated mobile pages and digital outdoor screens.
It is still expected, that every vendor participating in header bidding auctions
will adopt transactions IDs as well as identification of whether the SSP is
able to make the final decision or if it is laying in the upstream source.
Having this information, the DSPs could better optimise the trading and
implement suitable supply path optimisations without sacrificing the quality
and leaving more advertising money for the publishers.
41. Header Bidding and Auction Dynamics White Paper
41
All of the above will lead to full first-price auction adoption and
enhance transparency in the programmatic advertising ecosystem. Further
guidance on enhancing transparency in the digital advertising supply chain
can be found in the IAB Europe Transparency Guide. The guide provides
questions for each stakeholder category to be asked at different stages of
the supply chain.
