Entity authority is the degree to which an AI system or knowledge graph trusts a specific entity as a reliable source or subject within its domain. It is built from the quality and quantity of structured signals about the entity across verified, authoritative sources.
Entity authority is the entity-level version of site authority. A brand with high entity authority — verified across Wikidata, Wikipedia, schema markup, and widely-cited third-party coverage — is more likely to be retrieved, cited, and accurately represented than a brand whose entity signals are thin or inconsistent. Entity authority compounds over time and cannot be manufactured quickly — it is the result of consistent, accurate, structured presence across the web.
