AI traffic from GA4
Measure the real sessions and conversions that AI assistants drive to your site.
What it does
AI visibility tells you whether ChatGPT, Gemini and Perplexity mention a brand. AI traffic closes the loop: it shows how many people those assistants actually send to the website, and what they do once they arrive. Once a Google Analytics 4 property is connected, CrunchJunky can isolate the sessions, engaged sessions, key events and revenue that originate from AI assistants — turning "we're visible in AI" into a number you can put in front of a client.
How AI traffic is identified
GA4 records the referring source of every session. CrunchJunky matches that source against the hosts AI assistants use — chatgpt.com, chat.openai.com, perplexity.ai, gemini.google.com, copilot.microsoft.com, claude.ai, you.com, poe.com and a few others — and groups them as "AI Source". Because the match happens on GA4's own first-party data, it's accurate and needs no tags, scripts or extra tracking. As new assistants gain referral traffic, the source list is kept up to date.
Adding it to a report
The fastest route is the "GA4 — AI Assistant Traffic" template: in the report builder, choose Google Analytics as the source and pick that template. It comes pre-built with a per-assistant breakdown table and two donut charts (sessions and key events by assistant), plus an AI-written summary.
To add it to an existing report, drop in a Table or Breakdown (donut) widget on a GA4 data source and set its dimension to "AI Source". You can pair any GA4 metrics with it — Sessions, Users, Engaged Sessions, Engagement Rate, Key Events or Revenue — to show both the volume and the quality of AI-driven traffic.
Reading the numbers
Look at three things together. Volume (Sessions, Users) shows how much traffic AI is sending. Engagement (Engaged Sessions, Engagement Rate) shows whether that traffic is genuinely interested — AI-referred visitors often engage more deeply because the assistant has already qualified their intent. Outcomes (Key Events, Revenue) show whether it converts. Comparing the same report period-over-period reveals whether improving a brand's AI visibility is translating into real, growing traffic and conversions.
