Measuring AI referrals to your site
Short answer
AI engines already send measurable click-through. A single GA4 channel group with the right source filters exposes the traffic — and the conversions — you've been missing.
Key Takeaways
- perplexity.ai, chat.openai.com, copilot.microsoft.com and gemini.google.com are the four core AI sources.
- Engaged sessions from AI referrals convert higher than typical organic for buyer-intent queries.
- AI-referred revenue is usually small but measurable once you set up attribution; track your own baseline.

Frequently asked questions

Direct clicks are only one of three effects. Brand recall and follow-up branded searches can matter as much as direct clicks but are harder to measure.
