ChatGPT Ads scale to 89 countries and 100,000+ advertisers and Google switches on ads in AI Mode — yet fresh data shows AI still sends a sliver of Google's referral traffic, even as Google Search traffic to publishers falls 40% in a year.
The through-line this week is attention shifting onto AI surfaces and away from classic blue links. Ads are now live inside both AI Mode and ChatGPT, Google referral traffic to publishers is down ~40% year-on-year, and the much-reported "ChatGPT traffic collapse" turned out to be a GPT-6 tracking bug — so measure carefully before reacting. In parallel, Google kept shipping commerce (Universal Cart) and trust features (Business Profile ID verification).
