StackAdapt is now a technology partner for ads in ChatGPT, giving advertisers access to the pilot program through its AI advertising platform.

Snapchat launched conversational brand agents, PayPal dropped a deterministic identity graph on 400M accounts, Google AI Max hit 7% conversion uplift, and a free tool ports your Google Ads to ChatGPT in five minutes.

Four marketing signals worth tracking this week: ChatGPT pivots to cost-per-click at $3–$5 per click, Meta faces a class action over alleged scam ad revenue, Microsoft structures product data for AI agents, and the IAB puts a $26B number on broken measurement.
