## Definition

A citation gap is a relevant query or topic area in which a brand is not being cited despite having legitimate authority and relevant content — a gap between the brand's actual expertise and its AI citation footprint.

## Why It Matters for AI Search

Citation gaps are the most actionable output of an AI citation audit. They identify specific query types and topic areas where the brand should be cited but is not — pointing directly to where content, entity, or technical optimization work is needed. A citation gap in a high-value query category is a concrete business opportunity: closing it means capturing AI-driven discovery for queries that represent real buyer intent.
