Where it appears
Source and medium, with values such as chatgpt.com / referral.
AI assistant traffic
The visits that come from AI answers.
Traffic from ChatGPT and other AI assistants shows up in Google Analytics 4 as referral traffic, with sources such as chatgpt.com or perplexity.ai. Reading it properly takes a dedicated channel group: find out how to create it and what stays invisible.
In brief
Where to find traffic from AI assistants.
When someone clicks a link in an assistant’s answer, the visit usually arrives with the assistant as its source. In GA4 it ends up among referrals, mixed with every other site: it needs separating.
What is needed
A custom channel group with a channel for assistants.
What is missing
Visits without a referrer and AI summaries within Google Search.
The sources
How assistants appear in GA4.
Each assistant leaves a different trace. Knowing the most common sources lets you write a rule that captures them all and notice when a new one appears.
The sources under which visits from AI assistants usually appear in Google Analytics 4, and a note on what to check for each.
| Assistant | Typical source | To be verified |
|---|---|---|
| ChatGPT | chatgpt.com, often with utm_source=chatgpt.com. | Also older sources with the previous domain. |
| Perplexity | perplexity.ai. | Links opened from the app may lose the source. |
| Gemini | gemini.google.com. | Don’t confuse it with organic Google Search. |
| Copilot | copilot.microsoft.com. | Visits from Bing remain a separate channel. |
| Claude | claude.ai. | Often low volumes: look at the trend, not the single day. |
The dedicated channel
Creating an “AI assistants” channel in GA4.
GA4 lets you create custom channel groups. You copy the default group, add a channel with a rule on the source and place it above the Referral channel, because the rules apply in order.
An example configuration of a custom channel in Google Analytics 4 that gathers visits from AI assistants, with the condition and the position.
Admin › Data display › Channel groups
- Channel name
- AI assistants, in a group copied from the default one.
- Condition
- Source matches regex chatgpt|openai|perplexity|gemini\.google|copilot|claude\.ai
- Position
- Above the Referral channel, otherwise the visits stay there.
- Verification
- Exploration by source: no assistant left in Referral.
What you cannot see
Three reasons why the count is partial.
Measured assistant traffic is a minimum, not the total. Saying so avoids underestimating the effect of AI answers or attributing it to the wrong channel.
Three situations in which a visit influenced by an AI assistant does not appear as such in GA4, where it ends up and how to spot it at least in part.
| Situation | Where it ends up | How to spot it |
|---|---|---|
| Apps that do not pass the referrer | In direct traffic. | Spikes of direct visits on the pages cited by answers. |
| AI summaries within Google | In Google organic search. | Search Console includes them in Web performance. |
| Answers read without clicking | Nowhere: there is no visit. | Searches for the brand name growing over time. |
Reading the numbers
What to say, and what not, to decision makers.
Visits from assistants are often few but qualified. They are read by landing page and over time, alongside what the answers say about the brand.
Three common statements about AI assistant traffic set against a more accurate reading, to use when presenting data to decision makers.
| Hasty reading | Correct interpretation | |
|---|---|---|
| Volume | They are few visits, so AI doesn’t matter. | They are the measurable visits: many answers generate no clicks. |
| Pages | AI traffic lands on the home page. | What matters is which pages it lands on: those the answers cite. |
| Trend | A jump in one day is a success. | Look at the trend over weeks, with the same channel group. |
Frequently asked questions
Frequently asked questions about ChatGPT traffic in GA4.
Where to see ChatGPT traffic, how to treat AI Overviews, why the data is incomplete and whether the channel group also works on past data.
Where do I see ChatGPT traffic in Google Analytics?
In Traffic acquisition, by source or medium: it appears as chatgpt.com. With a custom channel group you see it gathered in a channel of your own.
Is traffic from Google AI Overviews shown separately?
No. According to Google it falls under organic search and Search Console’s Web performance, with no separate line.
Why do the numbers look low?
Because many answers produce no click and some apps do not pass the source. The measured figure is a minimum, to be read over time.
Do changes to the channel group also apply to past data?
Custom channel groups in GA4 also apply to historical data in reports, because they classify visits when you display them.
