sameAs (Schema Property)

sameAs is a schema. org property that connects an entity on your site to its canonical representation elsewhere on the web — typically Wikidata, Wikipedia, official social profiles, Crunchbase, and authoritative directories. A single Organization JSON-LD block with a well-curated sameAs array is one of the highest-leverage entity-signal moves available. Why it matters: sameAs is how AI engines and search engines confirm that the "Smart Money Media" mentioned on this site is the same Smart Money Media in the Knowledge Graph, Wikidata, and across the social web. Strong sameAs arrays directly increase entity confidence, knowledge-panel eligibility, and AI citation likelihood.
