Glossary
Citation Share
The percentage of AI-cited sources that come from your domain across a tracked set of queries.
Definition
Citation share is to AI search what backlink share or organic traffic share was to traditional SEO — a measure of how much of the AI ecosystem's answer-supporting evidence comes from your site. A high citation share means AI engines trust your content as a source of truth in your category. A low or zero share means even if your brand is mentioned, the supporting links go to competitors or third parties.
Example
Across 100 tracked queries about email marketing, your domain appears as a cited source in 12 of them, your top competitor in 27. Your citation share is 12%.
