Citation rate is the share of relevant AI answers in which your content is cited as a source. If an engine answers 100 queries in your category and links your pages in 18 of them, your citation rate for that set is 18%.
Why it matters
Citation rate goes a step beyond mention rate. Being mentioned means the answer named your brand; being cited means your page was credited as the source the answer drew from. For citation-first engines like Perplexity and Google AI Overviews, citations are visible and directly attributable — making citation rate one of the most concrete, observable AEO metrics.
How to use it
- Track it per engine and per query cluster, not just overall, to see where you’re winning.
- Pair it with position — a citation high in the source list carries more weight.
- Tie it to content changes — rising citation rate after publishing or updating a page is strong evidence your AEO work is paying off.
