Entities and structured data
sameAs (schema.org)
Also called: sameAs
sameAs is a schema.org property that lists web pages which clearly show the identity of the thing described, such as its Wikipedia page, its Wikidata entry or its official profiles.
In plain words
Schema.org defines it as the URL of a reference web page that unambiguously indicates the item’s identity.
In practice you add it to your Organization or Person markup and list your official profiles.
Example
A small bakery adds its LinkedIn and Instagram pages to sameAs. Machines can then connect the website and those profiles to one and the same business.
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Example Bakery",
"url": "https://example.com",
"sameAs": [
"https://www.linkedin.com/company/example-bakery",
"https://www.instagram.com/examplebakery"
]
}Why it matters for AI search
It ties your website to your other profiles, so systems can tell that they all describe the same organization.
Schema.org names a Wikipedia page, a Wikidata entry or an official website as typical values.
