Ad industry tallies early losses from Apple Safari tracking block

Apple's latest Safari update has blocked tracking technologies used by major ad tech vendors, causing early revenue losses for publishers. Aditude reported a 10.5% drop in eCPMs among updated users, with Safari accounting for 11.7% of ad impressions and 11.4% of ad revenue for its clients. The impact is currently limited as only 8% of users have updated, but fears grow ahead of Q4. Some publishers with subscription models are less affected, while others worry about dependencies on blocked vendors. Apple's lack of communication and perceived favoritism towards its own ad network have drawn criticism. Index Exchange remains unaffected but calls the move an overreach. The Trade Desk's ad server was blocked but temporarily restored in a test version after a bug report.

• Apple's Safari update blocked tracking technologies used by major ad tech companies.
• Aditude reported eCPMs fell 10.5% among users with the update, impacting publishers' revenue.
• Safari accounts for 11.7% of ad impressions and 11.4% of ad revenue for Aditude's clients.

Index Exchange CEO: Sell-Side Innovation, CTV Transparency, AI Agents

In an interview with ADZINE, Andrew Casale, CEO of Index Exchange, discusses the evolution of programmatic advertising. He argues that sell-side innovation, including modeling and containerization, is increasing complexity but also value. Buyers can now run their own models on the sell-side, democratizing decision-making. Casale addresses the black box concern, noting that while the internal logic of buyer models is opaque, the platform observes their actions. He highlights the shift towards modular infrastructure, with Index enabling data providers and DSPs to run modules on its cloud. Regarding CTV, Casale emphasizes the need for more transparency, noting that while genre data is increasingly available, show and episode data remain limited due to legal and distribution issues. He discusses the evolution of pod serving and the role of agentic advertising, distinguishing between workflow automation and impression-level decisioning, which remains the domain of mathematical models. Casale sees AI agents as useful for automating manual tasks but not as a revolution that will shift power from walled gardens.

• Index Exchange processes around 20 million requests per second.
