sameAs vs knowsAbout: you're using the wrong entity property
Teams stuff every Wikipedia and LinkedIn URL into sameAs and wonder why disambiguation still fails. The two properties answer different questions. sameAs says 'this IS the same entity, here are its other identities' — Wikidata, official social, Wikipedia. knowsAbout says 'this entity has expertise in these topics.'
— sameAs: only canonical identity references, ideally anchored to Wikidata and Google's Knowledge Graph
— knowsAbout: topics, subjects, areas of authority — the E-E-A-T signal
— Never mix: a topic URL in sameAs corrupts the identity claim
What it means for you: a tight sameAs of 3-5 authoritative identity links beats 15 random social profiles for getting an entity recognized. knowsAbout is where you signal expertise. Watch this: as AI search leans on entity graphs to decide who to cite, the precision of sameAs is becoming a ranking input, not decoration.
