Definition

Retrieval frequency is how often a specific piece of content or source is retrieved by AI systems across a defined set of relevant queries — measured by the rate at which the content appears in AI-generated responses as a cited or referenced source. Retrieval frequency is the content-level equivalent of brand citation rate. Where citation rate measures how often a brand appears, retrieval frequency measures how often a specific piece of content is retrieved — identifying which assets are doing the most work in AI search. High retrieval frequency on a specific page indicates it is well-structured, semantically relevant, and trusted by AI retrieval systems. Low retrieval frequency on content that should be performing well points to indexability, entity, or structural optimization gaps.
