Citation

A citation is a link to a source page that an AI answer shows to back up what it says. Google shows them as supporting links in AI Overviews and AI Mode, Microsoft Copilot cites pages in its answers, and Claude's web search help page says that with web search on, "every response includes citations, so you can easily verify sources yourself."

Citations and mentions

A citation and a brand mention are different things. An answer can cite your page and name a competitor in its text, or name you while citing someone else's review. Track both: mentions show whether buyers hear your name, and citations show which pages the engine relies on.

Why they matter

Citations show where an engine gets its view of your category, and they carry the clicks an answer sends. The cited pages are often not the ones that rank. In a 2025 Ahrefs study of 15,000 long-tail queries, only 12% of links cited by ChatGPT, Gemini and Copilot appeared in Google's top 10 for the same prompt. Perplexity's citations overlapped more, at 28.6%.

How they're measured

• Google Search Console counts a click on a link in an AI Overview or AI Mode as a click, and gives every link in an AI Overview the same position: the position of the overview.
• Bing Webmaster Tools has an AI Performance report that counts citations of your pages in Microsoft Copilot and Bing's AI summaries, page by page.
• Other engines: log the cited URLs in each run and count how many runs cite each domain and page.

Cited pages that name your competitors but not you are your citation gaps, and they make a good first work list.
