Ad Tech's Server-Side Shift: Can It Counter Apple and Google?

In a recent Digiday Podcast episode, editors discussed the ad tech industry's response to Apple's Safari blocking of identity resolution domains and Google's ad tech antitrust remedies. Ad tech firms, including The Trade Desk and ID5, are moving ad calls server-side, with IAB Tech Lab's Trusted Server technology as a potential solution. However, experts question the durability of this approach, as Apple may find new ways to restrict tracking. Meanwhile, Google's remedies ruling could allow Prebid to alter the programmatic auction dynamics. The podcast highlights the ongoing power struggle between ad tech and browser/platform owners.

AI Slop Sites Rise: Ad Tech Faces New MFA Challenge

AdExchanger podcast discusses Apple's latest move to block identity resolution companies from tracking users on Safari, continuing its crackdowns on cookies and CNAME cloaking. Cybersecurity researcher Zach Edwards, founder of DecryptAds, notes Apple's dominance and advises ad tech to focus on consent and safer identity schemes. The episode also covers DecryptAds' report on over 2,100 AI-generated recipe sites, which mimic made-for-advertising (MFA) sites with fabricated author profiles and AI-generated avatars. These sites are monetized through programmatic supply chains involving SSPs like HBAgency, Ezoic, and MonetizeMore, with connections to risky geos such as Russia, China, Turkey, and UAE, raising brand safety and cybersecurity concerns. Google's new policies label fabricated creator profiles as deceptive, potentially affecting monetization.

UK Marketing Budgets Rise Across All Categories in Q3

The IPA Bellwether Report for Q3 2026 indicates a broad recovery in UK marketing budgets, with a net balance of +14.3% of marketers increasing spend—the highest in nine quarters and the third consecutive quarterly growth. All main media subcategories saw upward revisions for the first time, including main media (+9.8%) and 'other online' (+17.2%). PR (+15.3%) and events (+15.1%) led growth, followed by sales promotions (+13.1%). Despite this, industry and company-level financial confidence remain negative, though improved from Q2. S&P Global raised UK GDP growth forecasts for 2026 to 1.2%, supported by events like the FIFA World Cup, but risks from geopolitical tensions and high fuel prices persist. Ad spend forecasts were revised up for 2026 to 2.8% but down for 2027 to 1.3%. Industry experts offer mixed reactions, highlighting opportunities in creator marketing, out-of-home, audio, and video, while cautioning about walled gardens and the need for data quality and attention measurement as AI becomes more prevalent.

Prebid Proposes Ad Server Bid into Platform, Unbundling GAM

At the Prebid Summit in New York City on October 13, industry leaders discussed programmatic advertising's future, including challenges from Apple's iOS 27 and critiques of universal buying platforms. Alan Chapell predicted Google would 'claw back' antitrust remedies, Terry Kawaja likened UMPs to ad networks, and Ian Meyers highlighted transparency issues. Prebid proposed a new auction model to eliminate Google's alleged advantage: publisher ad servers would join the Prebid Server auction, bringing AdX into the same bidding process as other SSPs earlier, rather than competing later within GAM. This aims to reduce publisher reliance on Google Ad Manager and halve auction response time. The proposal, in public comment, targets formalization by Q1 2027, but implementation depends on whether Google uses Prebid.js or Prebid Server. Separately, Treasure AI transitioned from a CDP to an Agentic Experience Platform, though marketers' 'honeymoon phase' with AI agents is fading. Additionally, Google launched optional channel prioritization controls for advertisers on October 14.
