Citation Frequency
Citation frequency is the proportion of measured AI answers that link to a brand or its content as a source. The denominator must be stated clearly, such as all prompt runs or only answers containing citations, because different definitions produce different percentages.
In plain terms
It counts how often your pages are used as linked evidence in a defined test.
Why it matters
Citation frequency shows retrieval success, but it should not be confused with recommendation or commercial preference.
How to apply it
- Define the denominator before reporting the metric.
- Track citations by URL, prompt cluster and engine.
- Separate owned-site citations from third-party citations about the brand.
Example
If 40 prompt runs produce eight links to a vendor’s domain, its domain citation frequency is 20% for that test.

Ranking is no longer enough
You need to be cited, mentioned, and recommended.
Being cited, mentioned, and recommended are three different outcomes, and most brands only ever achieve the first one. Ranking is no longer enough because AI engines answer buyers directly and name only a short list of vendors as the recommendation — everyone else is cited in passing, if at all. Get a free AI Visibility Report to see exactly where your brand appears today across ChatGPT, Google AI Overviews, Gemini, Perplexity, and Copilot, where competitors are winning the recommendation instead, and what's keeping you from moving up the shortlist.
