How to see ChatGPT and AI traffic in GA4 (10-minute check)

Everyone is talking about AI search. Very few businesses have looked at the one place that tells them whether it already matters for them: their own analytics.

Here is a check you can do in about ten minutes, and how to read what you find.

How to check ChatGPT traffic in GA4: find AI assistants in your traffic sources

In Google Analytics 4:

• Go to Reports, then Acquisition, then Traffic acquisition.
• Change the main dimension to Session source / medium.
• In the search box above the table, type chatgpt. You will usually see a source like chatgpt.com / referral.
• Repeat with perplexity, gemini and copilot.

Write down the number of sessions for the last 90 days. That is your baseline.

Why this works: OpenAI's publisher FAQ says ChatGPT automatically adds utm_source=chatgpt.com to the links it sends from its search results, so those visits are labelled clearly in analytics.

Step 2: See which pages AI sends people to

This is the more useful part.

• Go to Reports, then Engagement, then Pages and screens.
• Add a filter or comparison where Session source contains chatgpt.
• Look at the list of pages.

These are pages an AI assistant found useful enough to link to. They tell you what the AI thinks you are an expert in.

Step 3: Check Google's AI features in Search Console

Google's AI Overviews and AI Mode do not show up as a separate source in GA4. Google says traffic from these features is included in Search Console, in the Performance report under the "Web" search type, together with normal search results.

So the check here is different: look at which pages earn impressions for longer, question-style searches. Those are the searches where AI answers appear most.

Does Google Analytics track bot traffic?

No, and that matters here. GA4 automatically excludes traffic from known bots and spiders. AI crawlers also mostly fetch pages without running scripts, so they rarely trigger analytics at all. What you see in GA4 is the AI referral traffic that counts: people who clicked a link in an AI answer. To see the crawlers themselves, you need your server logs.

How to read what you find

You found AI visits, on a few pages. Good news. Those pages work. Look at what they have in common: usually a clear answer, specific facts and a page that loads fast. Do more of that.

You found AI visits on pages you did not expect. Also useful. Sometimes an old blog post answers a question better than your service page. Link that post to the service, and update it so the visitor has a next step.

You found nothing. Do not panic. Many small sites see little or no AI traffic yet, and some AI clicks may arrive without a source and show up as direct traffic. Treat this as your starting point, not a verdict.

What makes a page worth citing

When we look at pages that AI assistants link to, the same qualities keep coming back. They are the same qualities that help people:

• A direct answer early. The question in the heading, the answer in the first lines.
• Specific facts. Hours, locations, numbers, names. "From 3 to 6 weeks" beats "fast".
• Text, not images. Facts inside images or PDFs are hard for machines to read.
• Consistency. Your opening hours, services and address should match on your website, Google Business Profile and social profiles.
• One topic per page. A page that tries to answer everything answers nothing well.

Google is clear that there is no special trick: no extra markup or AI file is needed for its AI features. A page must be indexed and eligible for a snippet. The rest is good, helpful content.

Why this is worth ten minutes now

Google keeps adding links inside its AI answers. On 15 October 2026 it announced more inline links in AI Mode and AI Overviews, and a test of a dedicated section that highlights official websites. In other words, being the clear, official source for your own topic is becoming more visible, not less.

The businesses that will benefit are the ones that know which pages already work, and improve them on purpose.

Your checklist

• GA4: note sessions from chatgpt, perplexity, gemini and copilot for the last 90 days.
• GA4: list the pages those visitors land on.
• Search Console: note pages with impressions for question-style searches.
• Improve the top three pages: direct answer first, specific facts, a clear next step.
• Check again in 30 days.
