EU Cookie Consent Test Finds Widespread Non-Compliance

Executive Signal Summary

Ebiquity and Usercentrics conducted an EU-wide cookie consent test on the 1,000 largest publishers in Europe (from a European IP address). The study found a large share of cookies are non-compliant, with more than half of third-party cookies originating from about 2,074 adtech companies. Alarmingly, one-third of these marketing cookies fire on publisher sites before user consent is provided. The analysis also revealed that 70% of cookie-based adtech players transfer data outside the EU, highlighting GDPR-related privacy risks. The piece discusses the implications for consent, data transfers, and measurement biases in audience targeting, using concepts like the Find-Back ratio to illustrate scaling challenges. It references GroupM’s global media spending forecasts and argues that demand for first-/third-party data persists despite tighter privacy rules.

Ad Awareness Regains Place in Effectiveness Planning

A new study by Thinkbox, Ebiquity, WPP Media, and Gain Theory, presented at the IPA Effectiveness Conference, analyzes 1,478 brands and 328,000 observations to argue that ad awareness is a valuable lead indicator in advertising effectiveness, not just an obsolete metric. The research finds that ad awareness accounts for 17% of brand consideration, of which only 6% is direct, while 11% works indirectly by improving brand perceptions. It also reports category-specific impacts, such as 69% in QSR delivery and 62% in lotteries. The author, Andrew Tindall, recommends that marketers reinstate ad awareness as a KPI, balancing it with attention and emotion in effectiveness planning.

Sony Proactively Shared WPP Rebate Probe Details

New court filings in the wrongful termination suit against WPP suggest that Sony voluntarily provided information to the defense regarding its own investigation into the holding company's business practices. The filings were made in the case brought by Richard Foster, former CEO of GroupM's Motion Entertainment, who alleges WPP retaliated against him for exposing an illegal rebate scheme. The amended complaint includes documents from Sony's investigation that corroborate Foster's whistleblower reports. The claim could upend WPP's previous motion to seal the documents and toss the case.
