How to find AI traffic in Google Analytics 4
In GA4, start with the Traffic acquisition report and inspect session source or source/medium values for AI assistant domains. Google’s report is designed to show where sessions come from; the exact values depend on what the referring browser passes to your site.
What the query can—and cannot—measure
Use session-scoped dimensions when asking where a session began. Add a landing-page dimension to see destinations, then compare engaged sessions or key events only if your event setup is correct. Save your filter logic and keep raw values available so that a channel grouping can be reviewed later.
A practical way to do it
Review source values in the selected date window before writing a regex. Include only observed domains, test the filter against known rows, and update it when the source list changes.
A useful checklist
- Open Traffic acquisition and use a session source dimension.
- Filter for observed AI assistant source values.
- Break down by landing page and a verified key event.
Limits to keep in mind
This is a report of trackable sessions, not every answer impression, citation or AI-influenced visit. Google-origin AI surfaces can blend into organic traffic.
Questions
Which GA4 report should I use?
