Entity Authority
The degree to which a website or content creator is recognised by Google\'s Knowledge Graph and AI systems as an authoritative source on a specific topic entity — a key component of topical authority and E-E-A-T signals.
Definition
Entity authority is the extent to which a named entity (a person, organisation, or brand) is associated with expertise on a specific subject in Google\'s entity understanding systems. Unlike domain authority (a link-based proxy metric), entity authority is about how well Google\'s Knowledge Graph and AI systems recognise an entity as a reliable, expert source on a topic. Signals that build entity authority: (1) **Knowledge Panel presence** — Google surfacing a Knowledge Panel for a person or brand on queries about them signals strong entity recognition. (2) **sameAs markup** — Person and Organisation JSON-LD with `sameAs` properties pointing to authoritative entity profiles (Wikipedia, Wikidata, LinkedIn, Crunchbase, official social profiles) helps Google connect the entity across sources. (3) **Citation in authoritative sources** — being cited in Wikipedia, news publications, academic papers, and authoritative industry sites reinforces entity recognition. (4) **Author entities** — named authors with consistent bylines, author pages with Person JSON-LD, and author profiles on external platforms (LinkedIn, Twitter/X) contribute to author entity authority for medical, legal, financial, and other YMYL content. (5) **Consistent entity mention** — the entity name being consistently used across the web (not variations, abbreviations, or different names) strengthens entity disambiguation.
Why it matters for SEO
Google\'s E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) evaluation uses entity authority signals to assess whether content creators and publishers are genuine experts on the topics they cover. In competitive niches, entity authority can be as important as backlink-based domain authority for ranking in positions where Google prioritises trusted sources.
How DeepSEOAnalysis checks this
DeepSEOAnalysis checks for entity signals on audited pages: Person and Organisation JSON-LD with sameAs properties, author markup on Article schema, and the presence of entity-linking signals that help Google connect the page to known entities in the Knowledge Graph.
