Track ChatGPT and AI assistant visits in GA4 and Shopify
Goal
Most ChatGPT traffic arrives with no referrer and lands in 'Direct'. A 1,000+ store study found 81.8% of it did. Set up a view that catches what can be caught, so you can see whether AI visibility work is paying off.

Prompt to copy
I use GA4 and Shopify analytics for a Shopify store. Help me measure visits and sales from AI assistants. Give me: 1) A GA4 custom channel group rule (exact conditions) for an 'AI assistants' channel, matching session source or referrer containing: chatgpt.com, chat.openai.com, perplexity.ai, gemini.google.com, copilot.microsoft.com, claude.ai, and utm_source=chatgpt.com. Put it above 'Referral' in the order. 2) An Exploration report that shows sessions, conversions and revenue for that channel by landing page. 3) How to see the same thing in Shopify (Analytics › Reports › sessions by referrer) and its limits. 4) A proxy for the untracked 'dark' share: direct sessions that land deep on product pages (not the home page) from new users. Explain clearly that this is an estimate, not proof. Keep it to setup steps I can follow in the current GA4 interface.
Steps
- Open GA4 › Admin › Data display › Channel groups and create a new group (copy the default first).
- Add the AI assistants channel using the AI's conditions.
- Build the Exploration and save it.
- Note the baseline this month, then check monthly alongside the AI prompt visibility test.
What to check
- The new channel sits above Referral, or the visits will be swallowed by it.
- You report AI-assisted numbers as a minimum, because most AI traffic shows as direct.
- No personal data is added to URLs or events.
