Similarweb has announced its newest Ad Intelligence data set, AI Ads, that fills an important gap for advertisers trying to understand the changing competitive landscape for ads in ChatGPT and Google's AI Mode and AI Overviews. The AI Ads Gallery shows what ads are running and in what context.
Similarweb launches AI Ads data set for ChatGPT and Google AI placements.
26% of ChatGPT responses already carry sponsored ads.
Nearly 30% of ad-eligible Google AI Mode queries show ads.
Over 40% of Google searches trigger AI Overviews with ads.
Insights drawn from real user panel conversations, not synthetic prompts.
Upcoming releases will add share of voice, ad categories, and conversational intent.
Most major ad channels have a public transparency layer: Meta has the Ad Library, Google has its Ads Transparency Center, and TikTok has the Creative Center. ChatGPT, AI Mode, and AI Overview, however, have none of that – not for competitors, and often not even for the advertiser's own team. Adding AI Ads to Similarweb's Ad Intelligence fills that gap with an Ads Gallery that shows what ads are running and in what context.
For AI Mode and AI Overview, advertisers participating in Google's broader digital advertising programs are blind to ad placements in Google AI answers. Most advertisers don't know whether their own ads are running in that context, let alone how they stack up against competitors. For ChatGPT, ads only show up when intent exists and is clarified from the conversation, and the decision comes down to the combination of ad creative, copy, and landing page. Similarweb's AI Ads provides a direct look at what's winning placement.
"This is the rare moment when a major ad channel is still wide open. The advertisers who can see what's happening with AI ads now will have a real head start. Until today, nobody could see it at all," said Harel Amir, General Manager & Head of Product for Similarweb Ad Intelligence.
"When we started advertising on ChatGPT, we were flying blind, no visibility into who else was in the auction or what was working," says Jonathan Bar Vardi, Head of Strategy at Natural Intelligence. "Similarweb changed that. It shows what other advertisers don't know: who's spending, where they're appearing, and what's driving performance."
