*Measurement* · *Citation & Visibility Measurement*

## 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.

## Why It Matters for AI Search

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](https://www.platelunchcollective.com/services/ai-seo) systems. Low retrieval frequency on content that should be performing well points to indexability, entity, or structural optimization gaps.
