## Definition

Entity coverage is the completeness of an entity's representation across authoritative data sources — including Wikipedia, Wikidata, schema.org markup, Google Business Profile, industry databases, and third-party publications. High entity coverage means the entity is well-documented across multiple independent sources.

## Why It Matters for AI Search

Entity coverage is the breadth dimension of entity optimization. A brand can have accurate entity data in one source but low coverage if most authoritative data sources lack entries for it. Improving entity coverage — adding Wikidata entries, pursuing Wikipedia notability, populating industry directories, earning press mentions — expands the corroboration surface that AI systems draw from when building entity representations.
