Google has never announced a general launch of ads in AI Mode. Every step so far is a test, a sighting or a confirmed experiment.
This page labels each one as such.
The test began at Google Marketing Live on 21st May 2025. Google said Search and Shopping ads "may appear below and integrated into AI Mode responses", from existing campaigns.
On 28th Aug 2026 a Shopping ads carousel was sighted inline within a response for the first time. On 4th Sep Google's Ads Liaison confirmed a "small experiment" serving exact and phrase match text ads.
Each step below links to its entry and primary source on our AI Mode tracker.
