sameAs
A schema.org property that connects an entity (Organization or Person) to its profiles on other authoritative sites.
sameAs takes an array of URLs pointing to the entity's profiles elsewhere: official social profiles, Wikipedia, Crunchbase, LinkedIn, professional directories. The property tells engines that the same entity exists across multiple confirmable sources.
A strong sameAs array is one of the cheapest entity-disambiguation signals available. AI engines weight it heavily when deciding which "John Smith Plumbing" you are.
