# Entity Authority

> 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.

*Core concept* · *Entity & Knowledge Graph*

## Definition

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.

## Why It Matters for AI Search

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.
