Similarweb launches AI Ads tool to track ChatGPT and Google AI ad placements
Google AI Mode shows ads in almost 30% of queries where placements are available, and more than 40% of Google searches now trigger an AI Overview that can carry ads, Similarweb says. The company launched AI Ads, a data set for tracking advertising inside ChatGPT, Google AI Overviews and Google AI Mode, along with AI Ads Gallery, a database of those placements broken out by country and market and built from real conversations between users and AI services. Similarweb plans to add share-of-voice metrics and ad category breakdowns. Harel Amir, general director and head of Ad Intelligence at Similarweb, said AI advertising is 'a rare moment when a major ad channel is still practically open.'
Competitor ad creative, ad copy and landing pages inside ChatGPT and Google's AI surfaces become visible for the first time, at a stage when few advertisers are running structured campaigns there. Google's Ads Transparency Center and TikTok's Creative Center already offer this kind of visibility on their own platforms; Similarweb extends it to AI chat and AI search, giving early movers a chance to benchmark placements and messaging before the channel gets crowded.
