AI Citation

An AI citation is a reference to a specific source — typically a URL or domain name — that an AI search engine includes in its generated response. When ChatGPT references a website or Perplexity attaches numbered source links, those are AI citations. They represent the primary mechanism through which AI search drives referral traffic to websites.

Citation Behavior by Platform

Citation behavior varies by platform. Perplexity uses numbered inline citations that link directly to sources. ChatGPT includes citations as footnote-style links when web search is activated. Google AI Overviews may include expandable source cards. Each format affects how users interact with the cited sources.

Value of AI Citations

AI citations are valuable because they provide both visibility and traffic. Research indicates that AI referral traffic converts at 4.4–6x the rate of traditional organic search, likely because users who click through from an AI recommendation have high intent.

Mentions vs. Citations

Not all mentions are citations. A brand can be mentioned by name without a corresponding source link. Both are valuable — mentions build awareness, citations drive traffic — but tracking them separately provides clearer optimization insights.
