"The industry must now move to rectify the
issues and restore the productivity of billions
of dollars of marketing investments,“ said
Bob Liodice, CEO of the ANA

What the ANA RFP asked for …
The new study will add detail to prior studies, and separate “cost efficiency” from “ad effectiveness”
“Cost Efficiency” “Ad Effectiveness”

But …
• The numerous forms of hidden arbitrage, waste, and fraud cannot be depicted in a
simple waterfall chart (“if the definition of transparency is how much of my budget
makes it into the publishers’ hands, that's a very flawed baseline.”)
• Attempts to depict the losses and waste assumes you can see all of those problems
and requires you to make assumptions about what average is “most representative”
when in most cases “the extent is not known”
• The reality of “productive portion of an ad dollar” is too scary for a trade association
to publish truthfully; it is likely they will do what they have done before: position the
result with PR, which masks the truth, is misleading, and therefore is useless
• The recommendation “buy less programmatic” will not be tenable

Executive Summary
OBJECTIVE OF THIS STUDY
• Educate marketers on the inefficiencies, costs, hidden arbitrage, and risks associated
with buying through programmatic channels and how these outweigh the alleged
benefits of reach, targeting, and performance
• Enable marketers to take immediate action on these new insights, without re-
tooling, to optimize their digital ad spending, reduce waste and risk, and improve
actual business outcomes
All of the data compiled in this study come from 1) first-hand campaigns
where all variables are known, 2) documented cases published by others
publicly, and 3) data crowdsourced from practitioners anonymously

Prior Transparency Studies
Supply chain studies since 2014 corroborate that only 40 – 61% of dollar makes it to pubs for showing ads
ISBA 2020: 51%
“publishers received half of advertiser spend.
15% of advertiser spend – the unknown
delta, representing around 1/3 of supply
chain costs – could not be attributed.”
Source: ISBA, May 2020
“went missing”
Source: WFA, Sep 2014 Source: ANA, May 2017
WFA 2014: 40%
“We have little or no clear understanding of what
percentage (of digital spend) is being delivered to
the media owner and what is being taken in fees
from either the agency or middlemen. ”
ANA 2017: 60%
“Programmatic remains complex and often
non-transparent. Our study revealed that
this lack of transparency makes it difficult for
advertisers to manage, measure and audit
programmatic media investments.”

Directly Measured Ad Blocking
Direct measurement is necessary, measurement done on-site
• Ad blocking must be measured on-site. In-ad measurements are invalid
• Desktop and mobile must be separated because ad blocking in mobile is
very low (no plugins for mobile browsers, and most consumers don’t
regularly use ad blocking browsers, they use built-in browsers)
• Bots and “not measurable” must be excluded because bots don’t block
ads (their job is to cause them to load)
Business sites desktop mobile
ad block rate 8 - 17% 0.6 – 0.8%
Consumer sites desktop mobile
ad block rate 11 - 12% 0.9 - 1%

Malicious code to alter measurements
Common practice to manipulate/alter measurements to trick fraud detection
“the [malicious] code used by NMG is
designed to interfere with the ability of
third-party measurement systems to
determine how much of a digital ad
was viewable during a browsing
session.
This 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.”

• If fraud detection hasn’t seen a device
before, the default action is to let the ad
serve
• Frequency caps based on deviceIDs are
defeated, each device appears as new
• Valid deviceIDs are harvested from real
devices and sent to fake devices or apps to
replay
• Replayed deviceIDs are used by fraudulent
apps to defeat fraud detection

Industry Associations’ View
Trade associations look at invalid traffic (IVT) by fraud detection; severely underestimates
“The 11 percent decline in
two years is particularly
noteworthy” – ANA (2019)
“IVT is between
1 – 3%”
– GroupM (2019)
“IVT is 1.05%”
– TAG (2020)

Measure for Humans, not just for fraud
Optimizing for low CPMs may increase risk of ad fraud; optimize for humans instead
Lower quality paid
sources mean higher
cost per human – like
11X higher cost.
Sources of different
quality send widely
different amounts of
humans to landing pages.
“showing ads to humans is
the single most important
factor for better digital.”

Recommendations
• Previous supply chain studies showed that 50% of a marketer’s dollar goes to supply
chain costs, leaving 50 cents for “working media” in ideal conditions
• This study provides additional examples of “measurable issues” that further eat
away at the “working media” leaving far less money for showing ads.
• Many other issues are not depicted in the waterfall chart; but they remain sources
of cost and risk for marketers buying ads through programmatic channels
• Marketers should run their own “turn-off” experiments; also experiment with using
fewer targeting parameters; business outcomes and ROI should go up
• Marketers should shift dollars to buying direct from good publishers, to reduce and
eliminate most of the supply chain costs and associated risks and waste
