Introducing AI Ads: See Who’s Advertising Inside ChatGPT, Google AI Mode, and AI Overviews

For the first time, marketers can see inside the ad surfaces that AI search created. Until today, that view simply didn’t exist.

Today, Similarweb has launched AI Ads, the newest channel inside Ad Intelligence. It gives you visibility into ads running inside ChatGPT, Google AI Mode, and Google AI Overviews so that you can see the actual creative, the actual landing pages, and who’s behind them.

Why this matters

Ads are already live inside ChatGPT, Google AI Mode, and Google AI Overviews. And right now, it’s a total black box. Nobody can see who’s advertising there, what their ads say, or when they started running. That’s a huge blind spot for a channel that isn’t playing by the old rules. 

And ChatGPT ads don’t work like search. There’s no keyword to bid on. Delivery is driven by the context of the conversation and the strength of the ad’s own copy and landing page, the same signals that Similarweb already captures.

That’s exactly the kind of signal Similarweb has always been built to capture. Because our data comes from real users in live, personalized conversations, we see the ads these platforms actually surface in genuine context, not the stripped, one-line synthetic prompts other approaches rely on, which can’t reproduce that context to begin with.

This is a rare, wide-open moment in advertising. The channel is new, most competitors haven’t figured it out yet, and the businesses that move first will have the clearest runway.

“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, Similarweb Ad Intelligence.

What you can do with AI Ads

At launch, AI Ads gives you:

• Ad creative libraries: The actual ads running in ChatGPT, not modeled or estimated metrics
• Landing pages: See exactly where that traffic is being sent
• Filters by Domain, Platform, Time range, and Country, so you can zero in on your category or a specific competitor

And because AI Ads lives natively inside Ad Intelligence, it connects directly to the search, display, and social ad data you’re already tracking. It’s one dataset, one login, and one place to see the full competitive picture, not a separate, bolted-on tool for this one channel.

Built for how AI search actually works

1. ChatGPT

Already running ads in there? Filter by domain to see exactly what your competitors’ creative and landing pages look like right now, and how your own messaging stacks up. Just getting started? See what’s already running in your category before you build your first campaign, instead of launching blind.

2. Google AI Mode & Google AI Overviews 

Google decides when and where these ads appear, so most advertisers have had zero visibility into their own presence here, let alone their competitors’. AI Ads shows you who’s actually showing up, including you.

Because our view comes from real usage rather than a fixed, pre-set list of prompts or categories, it surfaces advertisers and creatives you might not have thought to go looking for in the first place.

Getting started

AI Ads is available inside Similarweb’s Ad Intelligence module. At launch, ChatGPT coverage includes the top 10,000 US advertisers, and we’re expanding continuously from there.
