## Definition

Share of retrieval is the proportion of retrieval events for a defined topic or query category that return a specific brand's content — measuring how much of the total retrieval activity in a topic area a brand captures relative to all sources being retrieved.

## Why It Matters for AI Search

Share of retrieval measures how often a brand's specific content is retrieved by AI systems across a defined set of topic queries — tracking which content assets are doing the most work in AI search and identifying which competitors are capturing retrieval events the brand should be winning. Tracking share of retrieval helps identify which competitors are capturing retrieval events that the brand should be winning — and which content gaps or structural improvements would shift that balance.
