AdTech Week in Review: May 13–19, 2019

A curated digest of the week's most relevant AdTech stories — maximum signal, minimum reading time.

The Next Big Source of Ad Fraud: Attribution [MediaPost]

Airbnb and its verification partner Impact USA surfaced some striking fraud figures at the I-COM Global Summit, pointing to attribution manipulation as an emerging vector for affiliate fraud.

Key points:

• Conventional advertising fraud already accounts for one out of every three dollars spent by digital advertisers
• Fraudulent activity has been traced to both the supply and demand sides of Airbnb's partnership models
• Fraudsters have cost Airbnb millions in affiliate commissions through manipulated attribution

The Walled Gardens Are Eating Open Programmatic [AdExchanger]

Google, Facebook, and Amazon pose a growing structural threat to independent AdTech — not just through their own inventory, but through aggressive participation in open programmatic markets.

Key points:

• Google, Facebook, and Amazon generate substantial revenue from their own inventory while simultaneously bidding into nearly every programmatic auction across the open internet
• Programmatic is still growing, but the growth is concentrated inside walled gardens while independent AdTech firms continue to struggle
• Programmatic ad spend is estimated to hit $49.8 billion in 2019, of which independent AdTech accounts for only $16 billion — and that share is shrinking

Data Consistency: The Real Challenge for Marketers in a Post-ITP World [AdExchanger]

The core problem isn't simply that Safari breaks certain tracking mechanisms — it's that the data a marketer sees from Safari may look wrong relative to Chrome, and it's not always obvious which dataset to trust when the discrepancy spans up to half the user population.

Key points:

• Chrome has introduced new privacy controls letting developers define whether their cookies can be used in a third-party context; users can block third-party cookies on an opt-in basis
• ITP 2.2 in Safari automatically blocks third-party cookies — breaking ad frequency capping, retargeting, and view-through attribution — while also capping first-party tracking cookies to either one or seven days
• On Safari, where view-through attribution is effectively impossible and clickstream data expires after one or seven days, the same user journey would be reported as: Display: one impression, no assisted visit or assisted conversion; Direct: one new visit, no last-click or assisted conversion; Paid search: one new visit, one last-click conversion
• On Chrome, where only opt-in users block third-party cookies and web analytics cookies are unaffected, that same journey looks considerably different: Display: one impression, one assisted conversion; Direct: one new visit, no last-click conversion, one assisted conversion; Paid search: one returning visit, one last-click conversion
• The result is two materially different attribution reports for the same user journey, depending solely on the browser

IAB Identifies Audience Mindsets as a Key Signal for Digital Video Targeting [Adtech Daily]

Released during the 2019 IAB Digital Content NewFronts, the IAB's A Day in the Life of Video Viewers study examines how consumer motivations and mindset at the moment of viewing shape receptivity to advertising — and what that means for targeting strategy.

Key points:

• IAB defines six mindset categories relevant to video consumption: Relaxation, Appointment, Spontaneous, Escapist, Educational, and Informative
• Viewers are significantly more attentive to both content and advertising when watching for educational or instructional purposes
• Mindset-based findings shift depending on which device the consumer is using, adding a device-layer dimension to any targeting strategy built around these signals
