sameAs
A schema.org property used to declare authoritative external profiles for an entity.
Full definition
sameAs is a schema.org property that links an entity (Organization, Person, Product) to its canonical representations on other sites — Wikipedia, Wikidata, Crunchbase, LinkedIn, Twitter, etc. It's how you connect on-page schema to the broader knowledge graph.
sameAs links are the single most effective signal for entity disambiguation. They turn a generic Organization JSON-LD block into a confidently identified knowledge-graph node — which makes AI engines far more willing to cite you by name.
Example
"sameAs": ["https://en.wikipedia.org/wiki/Acme", "https://www.wikidata.org/wiki/Q12345", "https://www.linkedin.com/company/acme"]

Is sameAs the same as SEO?
No. sameAs is one piece of the broader GEO (Generative Engine Optimization) program that sits on top of classical SEO. The two work together — classical SEO gets you crawled and indexed; sameAs is part of what gets you cited by AI engines.
Do I need a tool to implement sameAs?
For most teams, a free scanner like OptimAIze is enough to identify what's missing. Implementation is usually a copy-paste of generated markup or a small code change — no specialist tool required.
