What Is sameAs? Definition and Example

sameAs is a schema.org property that lists URLs which unambiguously identify the same entity, for example a company's official social profiles or its Wikidata item. Schema.org defines it as the "URL of a reference Web page that unambiguously indicates the item's identity" (schema.org). Google's Organization structured data documentation shows sameAs in its examples (Google).

What should and shouldn't go in it?

Example

Illustrative. A company with a common name has three different "X Labs" profiles appearing in AI answers. Adding sameAs links to its official LinkedIn, X and YouTube accounts gives systems an explicit, machine-readable statement of which profiles belong to it.

How do you check your sameAs?

1. View your homepage source or test it in Google's Rich Results Test.
2. Confirm every URL resolves and is still active.
3. Make sure the name and description match across profiles.

Why it matters for GEO

AI systems describe entities using whatever sources they can connect. sameAs is a small, explicit signal that ties your scattered profiles to one identity, reducing the risk of confusion with similarly named brands.

Common mistakes

• Listing every page that mentions you, which dilutes the signal.
• Leaving links to deleted or renamed profiles.
• Adding sameAs on every page with different lists; keep one consistent block.
