• Year-over-year, ad fraud has not improved overall; but
individual companies see improvements with greater effort
• Bots remain the key ingredient for all forms of ad fraud and
their actions are polluting analytics, making them unreliable
• Viewability standards are widespread now, but ad blocking
has emerged as the new “crisis du jour”
• Cybercriminals continue to easily avoid or defeat detection
technologies because they cheat and don’t play by any rules
• The proliferation of connected devices and IoT will increase
the capabilities of bots and opportunity for ad fraud
• 4D cybersecurity approaches are needed to fight ad fraud

Ad Fraud Background Update
April 2016 / Page 3marketing.scienceconsulting group, inc.
Year-over-year fraud estimates continue to vary widely
WhiteOps/DCN (Oct 2015)WhiteOps/ANA (Dec 2015)
Average Bots 3%
Range: 2% - 7%
Average Bots 11%
Range: 3% - 37%
“there are industry average bot% and very wide ranges;
but what really matters is the bot activity on YOUR site.”
April 2016 / Page 4marketing.scienceconsulting group, inc.
Bad guys continue to focus on where the money is
• rich media
not at risk
(86% of digital spend - 2014)
April 2016 / Page 5marketing.scienceconsulting group, inc.
Two main types of fraud have the same 2 key ingredients
(includes mobile display, video ads)
1. Put up fake websites and
load tons of ads on the pages
(includes mobile search ads)
2. Use bots to repeatedly load
pages to generate fake ad
impressions (hide the true
origins to avoid detection)
1. Put up fake websites and
participate in search networks
2. Use bots to type keywords
to cause search ads to load
and then to click on the ad
to generate the CPC revenue
April 2016 / Page 6marketing.scienceconsulting group, inc.
Bots are the cause of ALL automated ad fraud
Bots are made from 1) malware
compromised PCs or 2) headless
browsers (no screen) in datacenters.

“Ad fraud and ad blocking are
now related because of bots”

Bots of all kinds do all kinds of fraud

Advanced bots need to be detected differently
• found page via search
• observed events (mouse click
“Honest” (declared) bots
• search engine crawlers
• declare user agent honestly
• observed to be 1 – 5% of
• come from data centers
• malware compromised PCs
• deliberately disguised user

Fraud Activities Mess Up Measurement

Bad guys hide fraud by passing fake parameters

Bad guys fake KPIs, trick measurement systems
Bad guys have higher CTR Bad guys have higher viewability
Bad guys stack
ads above the
fold to fake
Good guys have to
array ads on the
page – e.g. lower

Turn off 1 ad network to cut out 90% bot traffic (red)
• Bot volumes are flat across (red line at top; green volume bars at
• Human traffic patterns are messy and irregular (blue line at top)
• Dark red area decreased after we turned off a single bad ad network
• Share blacklists through central data repository to increase impact

Google analytics view of traffic from single fraud domain
Despite losing all of the traffic from these fake/fraud sites, there was no
change to the number of pledges, during the same period of time.
goal events – no change
“ … because bots don’t make donations!”

AppNexus example – cleaned up 92% of impressions
Increased CPM prices

“AppNexus aggressively detected and discarded fraudulent
inventory; good for them and good for those who buy from
them. This should be an example for publishers.”

What normal (human) traffic patterns look like (5 + 2)
• Notice the normal 5+2 pattern of weekday versus weekend traffic
• Human traffic is lowest between 2a – 5a , because humans sleep
• Bot volumes are now seen to be roughly tuned to human pattern
5 weekdays 5 weekdays

Connection with Ad Blocking
April 2016 / Page 25marketing.scienceconsulting group, inc.
Ad blocking impacts both CPM and CPC ads
Ad blocking ONNo ad blocking
April 2016 / Page 26marketing.scienceconsulting group, inc.
Humans use adblock, fraud bots don’t block ads
“We have long used ad block detection as a signal
for human users because humans use adblock.”
“Fraud bots that want the ads to load don’t block ads.”
Note that we focus on the % of ads that successfully loaded, not blocked.
80 – 85% loaded is a good rule of thumb

Debunk ALL assumptions and discard all averages
• Ad Fraud / Bots
• Ad Blocking
• Bots are low; list-based detection catches very little
• Bots are malware on PCs; more and more from data centers
• Bots are simple (cant fake clicks, mouse, scrolling); they do
• Ad blocking is lower in mobile; mobile is less measurable
• Ad blocking is higher among younger users; not necessarily
• Ad blocking is still in the single digits; look at “ads served”
• Higher CTRs are better; not if the clicks are fake
• Higher viewability is better; not if the sites fake viewability
• Data is reliable; not so if you don’t know bot/blocking levels

Harvard Business Review – October 2015
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
Fou’s 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 “bad-guy bots.” A bot is computer
code that runs automated tasks.
