What is citation rate in AI search?

What citation rate measures

A citation rate counts how many answers linked to a chosen source, then divides by a stated total. The chosen source is often your own website. It could also be one page, a directory listing or a competitor's website.

Because the word citation can mean several things, the figure is only useful with its rule beside it. A different rule gives a different rate from exactly the same answers. The rate covers the answers you collected for your prompts, which are the questions sent to AI assistants. It does not describe all the answers an assistant gives to all the people who ask it. The rate tells you how often answers pointed to that source as evidence. It does not tell you whether the answer named you, described you correctly or sent anyone to your website.

Choosing the total you divide by

The most direct total is readable answers. That gives the share of answers that linked to your source, whether or not they carried any links at all.

Another total is answers with at least one source link. That figure leaves out answers that gave no sources, so it reads higher from the same answers. Neither is wrong, but they answer different questions. Whichever you choose, leave out attempts that produced no readable answer. A failed attempt shows nothing about links. Report it separately, so readers know how complete the sample was. When no answer was readable at all, the rate is unavailable. Show it that way rather than as a measured zero.

What counts as a citation

An attached source link is the clearest case. The assistant presented it as evidence for its answer. OpenAI's guide to its web search tool describes these as inline links carrying the address and title of each source.

A web address typed into the answer text is different. The assistant wrote it but did not attach it as a source. Count it apart, or your rate will mix two kinds of evidence.

Reading a change in citation rate

Report each assistant on its own first. Google's guidance for site owners says AI Overviews may use different models and techniques. It adds that the responses and links they show will vary.

A rise or fall does not show its cause. An assistant may change how it searches, other websites may change and answers vary between attempts. A before and after sequence alone cannot separate these. Small totals move sharply. Show the counts beside the rate, so a reader can see when a single answer has moved it a long way.

How Carqo relates to citation rate

In Carqo, the AI visibility dashboard counts the answers that gave your own website as a source. Only an attached source link to your website counts, and a web address typed into the answer text does not.

Your own website counts only once you have proved you own it. Until then, the figure reads as not known rather than nought, so a blank is never mistaken for a measured zero.

In practice

1. Choose the total Pick readable answers or answers with any source link, and write the choice beside the figure.
2. Count attached links only Count answers with an attached source link to your chosen source, and keep typed addresses apart.
3. Show the workings Report the count, the total, the dates and the assistants alongside the rate.
