What is sameAs (Schema Property)?

sameAs is a property in schema.org structured data that tells search engines and AI systems: 'This entity is the same as the one at these other URLs.' For a Person or Organization schema, sameAs links typically point to LinkedIn, GitHub, Twitter/X, Crunchbase, Wikipedia, and other authoritative profiles where the entity has an established presence.

Search engines use sameAs to resolve entity ambiguity. If your website says you are 'Aryan Rawther' and your schema includes sameAs links to your LinkedIn, GitHub, and Crunchbase profiles, Google's Knowledge Graph can confirm you are a specific individual with a verifiable professional history — not one of potentially many people with a similar name. This entity confirmation is what powers Knowledge Panels and rich author cards.

For AI search engines, sameAs is equally important. When Perplexity or ChatGPT needs to decide whether to cite your content, it evaluates your credibility. A consultant with sameAs links to an active LinkedIn profile, published GitHub repositories, and mentions on industry sites has stronger entity signals than one with only a personal website and no cross-platform confirmation.
