sameAs linking is the use of the Schema.org sameAs property to connect an entity to its authoritative references across the web — an explicit declaration that all of them describe the same entity.
A sameAs array on a brand's entity home points outward to its other authoritative records: its Wikidata entry, its verified social profiles, its official destinations. Each link is a stated fact — this page and that record are the same thing. Where entity resolution otherwise depends on the engine inferring the connection, sameAs simply asserts it.
It is one of the strongest resolution signals a brand controls directly — no third party, no editorial gatekeeper. It stitches scattered references into one coherent identity and names exactly which external records the engine should trust as the same entity. For communications teams, sameAs linking is the practical mechanism that connects a brand's owned site to the third-party profiles AI engines already trust — closing the loop between earned presence and structured identity.
