âDigital ad fraud is at all time highs
â both in dollar and rate.
Most of the fraud is missed by fraud
detection tech, because bad guys have
better tech and easily trick or block them.â

Detection Tag Blockingââanalytics
tags/fraud detection tags are accidentally
blocked or maliciously stripped out
âmalicious code manipulated data to
ensure that otherwise unviewable ads
showed up in measurement systems
as valid impressions, which resulted in
payment being made for the ad.â

Executive Summary
Marketers can take control and fight fraud with analytics/insights
1. Marketers should not assume that fraud verification
vendors can detect fraud and stop it. There are
technical limitations to what can be measured, how
much is measured, and if it is measured.
2. Marketers should look at their own analytics to see
if there are still tell-tale signs of fraud.
3. Marketers should ask hard and detailed questions
of their verification vendors to assess whether they
are even doing what they claim they can do.

Questions to ask your
fraud detection vendor
7. November 2018 / Page 6marketing.scienceconsulting group, inc.
linkedin.com/in/augustinefou
Do they have in-ad vs on-site tags?
Tags tuned for in-ad versus on-site measurement are needed
In-Ad
(rides with marketersâ ad)
On-Site
(installed on-site by publisher)
0% humans
60% bots
60% humans
3% bots
âfraud measurements could be entirely wrong, depending on
where the tag is placed and where the measurement is done.â

Do they measure for humans?
Measuring for humans is crucial; as is reporting not-measurable
volume bars (green)
Stacked percent
Blue (human)
White (not measurable)
Red (bots)
red v blue trendlines
âFraud detection that only reports NHT/IVT is not correctâ
10% bots does NOT mean 90% humans

Do they check for other fraud? How?
Fraud detection looks for IVT(bots); may miss other forms of fraud
% bot + % site + % mobile fraud
% overall fraud = 23%, not 5%
5% 11% 7%

Do they sample the data?
Sampling can lead to large discrepancies and bad measurements
WRONG IVT Measurement

Incorrect, due to sampling

Can they explain their measurement?
If something is marked as fraud, why?... or not fraud, why?
âdetailed supporting data to show client why something was
marked as fraudulent, or marked as clean â not black box.â

1. fakesite123.com has to pretend
to be esquire.com to get bids;
2. fraud measurement shows high
IVT b/c it is measuring the fake
site with fake traffic
3. Fake esquire.com gets mixed with
real so average fraud rates
appear high.
4. Real esquire.com gets backlisted;
bad guy moves on to another
domain.

Why is obvious fraud getting through
After fraud filters, obvious fraud is still impacting campaigns
Repeatedly loading slideshow pagesâ
log file data easily shows strange
behavior, like slideshow pages loaded
sequentially, or not sequentially

Harvard Business Review
Excerpt:
Hunting the Bots
Fou, a prodigy who earned a Ph.D. from MIT at
23, belongs to the generation that witnessed
the rise of digital marketers, having crafted his
trade at American Express, one of the most
successful American consumer brands, and at
Omnicom, one of the largest global advertising
agencies. Eventually stepping away from
corporate life, Fou started his own practice,
focusing on digital marketing fraud
investigation.
Fouâs experiment proved that fake traffic is
unproductive traffic. The fake visitors inflated
the traffic statistics but contributed nothing to
conversions, which stayed steady even after the
traffic plummeted (bottom chart). Fake traffic is
generated by âbad-guy bots.â A bot is computer
code that runs automated tasks.
