AI Referral Traffic
Definition
AI referral traffic is website visits whose referrer is an AI product such as ChatGPT, Perplexity, or Gemini.
Full definition
Analytics tools attribute sessions when the HTTP referrer or equivalent points to an AI domain. Volumes are often small versus Google organic but can grow quickly and sometimes convert differently.
Industry studies report AI chatbots as a fraction of a percent of traffic on average panels, with ChatGPT usually the largest referrer. See Citation and AI Visibility.
