What is AI Referral Traffic?
AI referral traffic is the visits your site gets from AI assistants: someone asks ChatGPT or Perplexity a question, the answer cites your page, and they click through. It shows up in analytics with referrers like chatgpt.com, perplexity.ai, and gemini.google.com.
How to measure it
Create a referrer segment in your analytics matching the AI domains (chatgpt.com, perplexity.ai, gemini.google.com, copilot.microsoft.com, claude.ai). Track it as its own channel. The absolute numbers start small; the trend line and the conversion rate are the story.
Why it undercounts AI influence
Most people who act on an AI recommendation never click a citation. They read the answer, then search your brand name or type your URL directly, which lands in organic or direct traffic. AI referral traffic is the visible tip; branded search lift and direct traffic carry the rest of the effect. That is why measuring mentions inside answers matters more than counting referral sessions.
