How to See AI Referral Traffic in Google Analytics and Search Console

Can you see traffic from ChatGPT and other AI assistants?

Most traffic from AI assistants is visible, as referrals. When someone clicks a cited link in ChatGPT, Perplexity, Gemini, Copilot, or Claude, the visit usually arrives as a referral from that product's domain, and your analytics records the source. Some visits arrive without a referrer, particularly from apps, and those land in Direct, where nothing identifies them.

Google's own AI features are the exception. Clicks from AI Overviews and AI Mode come through Google Search, and Google reports them together with ordinary search traffic.

Which referrers identify AI assistants?

Five domains cover the major assistants. Look for them as the session source in Google Analytics, or as the referrer in any other analytics tool.

You may also see a campaign tag on some links, such as utm_source=chatgpt.com. If it appears in your reports, it identifies the same source, and the channel rule below catches it either way.

How do you set up an AI channel in Google Analytics 4?

Create a custom channel group with a channel for AI assistants. Google documents the steps, and even uses AI assistants as its example channel.

• In GA4, go to Admin, then Data display, then Channel groups.
• Click "Create new channel group". GA4 starts you with a copy of the default group.
• Add a channel named "AI assistants" with the condition: Source matches regex.
• Enter a pattern listing the assistants, for example: .*(chatgpt|perplexity|gemini\.google|copilot\.microsoft|claude\.ai).*
• Move the new channel above Referral, then click "Save group".

The order step is the one people miss. Google's documentation says "traffic is included in the first channel whose definition it matches given the current order of channels in the group." Left below Referral, the AI channel stays empty, because Referral claims those visits first. Google also says "custom channel groups can be applied to your reports retroactively," so the new channel shows past traffic too, not just visits from the day you create it.

The leading and trailing .* make the pattern work whether the condition matches the whole source value or only part of it, and Google's own example wraps every name the same way. Google's example is longer and also covers retired names such as Bard; an explicit list like the one above is easier to read and to update when a new assistant starts sending visits.

Where do AI Overviews and AI Mode clicks show up?

In Search Console, mixed in with everything else. Google says "sites appearing in AI features (such as AI Overviews and AI Mode) are included in the overall search traffic in Search Console," reported "within the 'Web' search type." There is no filter that separates them, so a tool that claims to report AI Overviews clicks precisely is estimating.

Google also claims those clicks are "higher quality (meaning, users are more likely to spend more time on the site)." That is Google's description of its own product, so compare it with engagement in your own analytics before relying on it.

What can analytics not tell you?

Analytics sees clicks, and in AI search most exposure never becomes a click. Pew Research Center found that people clicked a link inside a Google AI summary in just 1 percent of visits in March 2025. Being named in an answer can still matter, as awareness that turns into a branded search or a direct visit later, but no report will attribute it.

So measure two things. Track AI referral traffic in analytics, as above. And once a month, ask ChatGPT, Perplexity, Gemini, and Claude the questions your customers ask, and note which sources they cite. Search Console can turn up something analytics never shows, too. This site's own data includes search queries plainly written by AI assistants searching on a user's behalf, instructions included.
