How much traffic is AI actually sending you?
Most AI referral traffic lands in GA4 as direct or buried inside referral, so you never see it. This builds the GA4 channel group and UTM setup that pulls ChatGPT, Perplexity, Claude, and Gemini into their own bucket.

Install it
- In GA4, open Admin, then Data display, then Channel groups.
- Create a new channel group and call it something like AI assistants.
- Add a new channel at the very top of the list, named AI assistants.
- Set its condition to: Source matches regex, and paste the regex above.
- Save. New sessions get bucketed right away; existing reports stay as they were.
One honest caveat: roughly two thirds of AI traffic arrives with no referrer and still lands in Direct, so this captures the click-throughs you can see, not every buyer the model sent. It is the measurable floor, and it is a lot more than zero.
Tag the links you control
For links you place yourself (directories, profiles, syndicated posts), add UTMs so the click is unmistakable in GA4.
Why AI traffic is hiding in your analytics
AI referrals are slippery to measure. A large share of clicks from AI tools arrive with no referrer at all, so GA4 files them under Direct alongside your bookmark traffic. Google AI Overviews get counted as Organic. And the clicks that do carry a referrer get scattered across Referral with everything else.
The result is that the channel quietly growing fastest is the one you cannot see in a standard report. A dedicated channel group fixes the visible part: it gathers the referred AI clicks into one line you can actually watch climb.

Questions
Why does AI traffic show up as direct?
Many AI tools strip or omit the referrer when they link out, so the browser arrives with no source attached. GA4 has nothing to attribute it to, so it falls into Direct. The channel group here catches the AI clicks that do carry a referrer, which is the measurable floor.
Will this change my historical data?
No. A new channel group reclassifies sessions going forward and in any report that supports it, but it does not rewrite what already happened. You can apply the same regex as a filter in an Exploration to look back at past data.
Do I need GA4 specifically?
The channel group steps are written for GA4, but the regex works anywhere you can filter by source: Looker Studio, an Exploration, or another analytics tool that exposes the referrer. The sources are the same regardless of platform.
Is the source list complete?
It covers the major assistants people actually click through from. New tools appear often, so treat it as a strong starting point and add sources as you spot them in your own referral report.
