sameAs
sameAs is a schema.org property that links your entity to its authoritative profiles elsewhere, telling AI systems that all those pages refer to the same person or organization.
sameAs connects the dots between your profiles. It's a schema.org property that points from your page to your other authoritative presences — LinkedIn, Wikipedia, Wikidata, Crunchbase, official social accounts — explicitly asserting that they all describe the same entity.
For AEO it's a direct aid to entity recognition and the authority pillar. By stating that "this brand here" is "this brand on Wikidata" and "this profile on LinkedIn," sameAs helps engines unify your scattered presence into a single, trusted node — supporting how you appear in the knowledge graph. It's most powerful when it points to already-authoritative, corroborating sources rather than thin or self-controlled pages.
Example. A founder's bio uses sameAs to link their Wikidata entry, university faculty page, and verified social profiles. An engine reads those links and confidently treats all of them — and the work attributed across them — as one recognized person.
