AI referral traffic

AI referral traffic is the visitor stream originating from AI surfaces: users clicking citations in ChatGPT or Perplexity, links in Gemini answers, or AI agents fetching your pages on a user's behalf. It is typically small in volume but exceptionally high-intent — the assistant has already qualified the visitor's question before sending them.

Measure it by segmenting known AI referrers and user agents in your analytics, and watch it as a leading indicator: growing AI referrals usually confirm that your citations and mentions are climbing before any survey or brand study would show it.
