The document discusses optimizing the time to first byte (TTFB) of a website. It defines TTFB as the time it takes for the first byte of information to be sent in response to a request. It then provides tips for measuring TTFB and describes factors that contribute to TTFB like DNS lookup, SSL negotiation, and server response time. Various techniques are presented for improving TTFB, such as using a CDN, HTTP/2, browser caching, and content delivery optimization.

The .htaccess file is famous for helping us set redirects but it can also help improve our website’s loading times as well as help with some crawling and indexing issues that I will cover in a bit. Learn where the file can be found, how it compares to https.conf, how it can be used for redirects, deal with duplicate content, what performance issues it can encounter, how it can help you create custom 404 pages, how it helps you leverage browser caching, gzip, disable image hotlinking, add canonical tags and robots directives in the HTTP headers and what tools and resources can help you learn even more.

Log files: The Overlooked Source of SEO Opportunities

Robin Rozhon

HTTP/2 and Service Works are becoming more established, yet the SEO community lacks awareness of what they are what they may mean for us. A lot of us know we need to know about them but we manage to keep putting it off. However, for both of these technologies, the next 12 months are going to be the turning point where we really can't avoid learning more about them. Tom will provide and accessible introduction to both, with a focus on what they are, how they work and what SEOs need to know. If you have been scared of jumping in to them until now, this session will help get you up to speed.

HTTP cookie hijacking in the wild: security and privacy implications

Priyanka Aash

The widespread demand for online privacy, also fueled by widely-publicized demonstrations of session hijacking attacks against popular websites (see Firesheep), has spearheaded the increasing deployment of HTTPS. However, many websites still avoid ubiquitous encryption due to performance or compatibility issues. The prevailing approach in these cases is to force critical functionality and sensitive data access over encrypted connections, while allowing more innocuous functionality to be accessed over HTTP. In practice, this approach is prone to flaws that can expose sensitive information or functionality to third parties. In this work, we conduct an in-depth assessment of a diverse set of major websites and explore what functionality and information is exposed to attackers that have hijacked a user's HTTP cookies. We identify a recurring pattern across websites with partially deployed HTTPS; service personalization inadvertently results in the exposure of private information. The separation of functionality across multiple cookies with different scopes and inter-dependencies further complicates matters, as imprecise access control renders restricted account functionality accessible to non-session cookies. Our cookie hijacking study reveals a number of severe flaws; attackers can obtain the user's home and work address and visited websites from Google, Bing and Baidu expose the user's complete search history, and Yahoo allows attackers to extract the contact list and send emails from the user's account. Furthermore, e-commerce vendors such as Amazon and Ebay expose the user's purchase history (partial and full respectively), and almost every website exposes the user's name and email address. Ad networks like Doubleclick can also reveal pages the user has visited. To fully evaluate the practicality and extent of cookie hijacking, we explore multiple aspects of the online ecosystem, including mobile apps, browser security mechanisms, extensions and search bars. To estimate the extent of the threat, we run IRB-approved measurements on a subset of our university's public wireless network for 30 days, and detect over 282K accounts exposing the cookies required for our hijacking attacks. We also explore how users can protect themselves and find that, while mechanisms such as the EFF's HTTPS Everywhere extension can reduce the attack surface, HTTP cookies are still regularly exposed. The privacy implications of these attacks become even more alarming when considering how they can be used to deanonymize Tor users. Our measurements suggest that a significant portion of Tor users may currently be vulnerable to cookie hijacking. (Source: Black Hat USA 2016, Las Vegas)

How Apartments.com Automated Contextual Linking - Next10X Boston 2019

Jordan Silton

Contextual links placed inside content are one of the best ways to drive traffic gains for large marketplaces. At Apartments.com, we publish thousands of local guides across the country and found a better way to place and update contextual links both helping renters and search engines. In this spotlight session from Next10X Boston 2019, we dove into how we identified known entities in existing content, connected them to the right related content, and developed a refresh cycle to ensure links always stay up to date on our site. We explored a variety of techniques including natural language processing (NLP), an application of AI and machine learning, to hone our internal linking strategy, and we learned a few tricks along the way to scale internal linking that can help your organization too.

Towards Real-Time banking API's: Introducing Coral, a web api for realtime st...

Natalino Busa

Banks are innovating. The purpose of this innovation is to transform bank services into meaningful and frictionless customer experiences. A key element in order to achieve that ambitious goal is by providing well tailored and reactive APIs and provide them as the building blocks for greater and smoother customer journeys and experiences. For these API’s to work, internal processes have to evolve as well from batch processing to real time event processing. In this talk, after providing a brief introduction of the streaming computing landscape, we describe a RESTful API called “Coral” meant to design and deploy customized and flexible data flows. The user can compose data flow for a number of data streaming goals such as on-the-fly data clustering and classifiers, streaming analytics, per-event predictive analysis , real time recommenders. Once the events are processed, Coral passes the resulting analysis as auctionable events for alerting, messaging or further processing to other systems. Coral is a flexible and generic event processing platform to transform streaming data into actionable events via a RESTful API. Those data flows are defined via the Web API by connecting together basic streaming processing elements named “coral actors”. The Coral framework manages those coral actors on a distributed and scalable architecture. Streaming and real time data processing and analytics are the key elements to an improved customer experience. In this way, you can get the most targeted processing for your domain (marketing customization, personalized recommenders, fraud detection, real time security alerting, etc.). This streaming “data flow” model implies processing customers’ events as soon as they enter via web APIs. This approach borrows a lot from distributed “data flow” concepts developed for processor architectures back in the 80’s. The “Coral” streaming processing engine is generic and built on top of world class libraries such as Akka and Spark, and fully exposed via a RESTful web API.
