Entity SEO

Entity SEO emerged in 2017-2020 as Google's Knowledge Graph became more central to ranking. The shift in worldview: instead of "this page targets this keyword," the framing is "this organisation is the recognised authority on this topic, and this page is part of its topical coverage."

The tactics that distinguish entity SEO from page-level SEO:

• A canonical entity foundation. A stable Schema.org Person and Organization graph with @id references, resolved on a dedicated page, used consistently across the site. The schema guide covers the priority order.
• sameAs verification across platforms. LinkedIn, X, GitHub, ORCID, Wikipedia, Wikidata, conference speaker pages: the sameAs list is what lets engines resolve your entity confidently.
• Topical depth signalling. Comprehensive coverage of a topic across multiple linked pages (the topical authority play) signals "this entity is the go-to source for this topic" to entity-aware ranking.
• Brand mentions over backlinks. Mentions of your organisation on authoritative third-party sites, even unlinked, feed entity disambiguation. The classical link-graph still matters but is no longer the only off-page signal.

For AEO and GEO, entity SEO is the foundation. AI engines weight Person-attributed, Organization-anchored content meaningfully higher than anonymous or weakly-attributed content. A clean entity graph is the single highest-leverage piece of structural work in 2026.

The entity authority guide on GEO Compass is the operational programme.
