What is a citation in an AI answer?

A citation is the engine putting a link to your page among the sources of its answer, inside the text beside the sentence it took from you or in the list of sources under it, so the reader can open your page and check.

Some say "reference" or "source". At Tasadr (تصدَّر) we say citation and nothing else, because a quote can be text with no link, while a citation, for us, is always a link. It is one of the terms in the Tasadr glossary.

Each engine shows its sources its own way. This is what the engines' owners document about it, as we read their pages on 11 October 2026, and nothing they did not say.

• ChatGPT: OpenAI says answers that search the web may include citations in the text, each opening its source, and that the Sources button shows the cited sources and other related links.
• Gemini: Google says the Sources button sits at the bottom of the response or inline in it and opens a side panel with the links, and that if there is no button, Gemini gave no links for that response.
• Perplexity: Perplexity says every answer carries numbered citations linking to the original sources, so readers can check them.
• Google AI Overviews and AI Mode: Google says both show links to supporting websites, and that a page must be indexed and eligible to be shown with a snippet, and its site must not be excluded from them in Google Search Console's settings.
• Copilot: Microsoft says the AI Performance report counts the citations displayed as sources in Copilot answers and Bing's AI summaries, so for Microsoft the citation is a published unit of measurement.

A citation is a link inside an answer, a mention is your name in the answer with no route to you, and a rank is your page's place in a list of search results. One site can have all three, or be missing some.

For every answer we record one of four outcomes, and use the same names for them on every Tasadr page:

• Cited: your site's link is among the answer's sources, whether or not the engine named you.
• Mentioned: your name is in the answer, with no link to your site.
• Absent: an answer that neither cites your site nor names you.
• No answer: the engine wrote no answer to the question that time, and it is never counted against you.

Real report · names hidden · 7 October 2026. We measured 8 questions that patients of a clinic group in Riyadh and Jeddah ask, on 8 engines, and the group's site was cited among an answer's sources on only 3 of the questions.

That was 8 answers out of the 61 the engines wrote. On the other five questions no engine relied on it, and the sites most often cited instead were an appointment-booking platform, a doctors' directory and a private hospital.

The full report, with its eight questions and who took the group's place on each, is the sample report.

You see some of them in Google's and Bing's reports for site owners, and some only by asking the engine yourself: we found no comparable report for site owners from the chat engines.

• Google Search Console: the Search generative AI performance report, since June 2026, counts impressions of your site's links in AI Overviews and AI Mode; it does not mention the Gemini app.
• Bing Webmaster Tools: the AI Performance report counts the citations themselves, how many of your pages are cited, and the phrases the AI searched with when it retrieved them, across Copilot and Bing's AI summaries.
• ChatGPT, Gemini and Perplexity: ask them your customers' questions and read the sources yourself. The method for Gemini, step by step, is in how can I tell if I'm being cited in Gemini?

It makes the sentence, not the page, the unit of work: an engine cites your page for a sentence it needs. So write sentences worth citing: the direct answer, the number with its date, the condition with the city's name.

Watch which page the engine cites, not your site as a whole. If it cites an old article instead of your service page, start there. What pages ChatGPT cites have in common is in cited compared with mentioned in ChatGPT.
