AI tools like ChatGPT, Google Gemini and Perplexity are quickly becoming part of how people discover websites. Instead of searching Google directly, users are asking AI tools questions – and sometimes, those tools recommend your site.
But here’s the catch: GA4 doesn’t yet have a neat “AI traffic” channel – at least not yet anyway. If you don’t filter it out (or isolate it), AI referrals will get lumped into referrals or organic search, making it difficult to measure the impact.
But, you can create a custom segment in GA4 to track traffic coming from AI tools. Let’s show you how.
Step 1: Open GA4 Explorations
-
Log in to your GA4 property.
-
In the left-hand menu, click Explore.
-
Click + Create new exploration.
Step 2: Build a Segment for AI Tools
-
In your new exploration, click Add segment.
-
Choose Session segment.
-
Under Condition, select Session source/medium.
-
Change the match type to matches regex.
-
Paste in the following regex and click save:
(chatgpt|openai|anthropic|deepseek|grok).com|(gemini|bard).google.com|(perplexity|claude).ai|(copilot.microsoft|edgeservices.bing).com|edge\scopilot
This regex captures traffic from:
-
ChatGPT (when it links to your site)
-
Google Gemini
-
Perplexity search
-
Claude’s browsing
-
Bing Copilot
-
You.com AI search
-
Anthropic
Step 3: Create Two Segments
To get the most out of this analysis, you can create both:
-
AI Tool Traffic: Shows only visits from AI tools (what we’ve created above)
-
Exclude AI Tools: Filters them out so your “traditional” traffic analysis isn’t skewed
Step 4: Analyse the Behaviour
Once applied, you can compare how AI-referred users behave versus your other channels.
Why is this important?
It’s a whole new channel of discovery that didn’t exist two years ago.
Your attribution models don’t yet account for AI referrals. But with this setup, you can start measuring it and get ahead of the curve.
