sameAs
How to fill sameAs in structured data to link an entity with official social profiles and strengthen the Knowledge Graph.
In brief
sameAs is a Schema.org property (array of URLs) that points to pages representing the same entity (organization, person) on other platforms such as Facebook, Twitter, or Wikipedia. It helps Google unambiguously identify the entity.
What is sameAs
sameAs is an array of URLs in Schema.org markup that links an organization or person to their official pages on external sites. Google uses these links to build the Knowledge Graph and improve the Knowledge Panel.
Example for an organization:
JSON
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Example Corp",
"sameAs": [
"https://facebook.com/example",
"https://twitter.com/example",
"https://linkedin.com/company/example",
"https://instagram.com/example",
"https://youtube.com/@example"
]
}For a person:
JSON
{
"@type": "Person",
"name": "Ivan Ivanov",
"sameAs": [
"https://twitter.com/ivanov",
"https://linkedin.com/in/ivanov",
"https://github.com/ivanov"
]
}Requirements for URLs
- Only official, active profiles (no fan pages or fakes).
- Full URLs (not shortened links).
- Pages must belong to the same real-world entity.
- More authoritative profiles increase Google's confidence in linking the data.
Do not add URLs that point to a different entity (e.g., a partner). This will confuse the Knowledge Graph.

Common questions
No, but it strengthens identity signals. It is highly recommended for brands and public figures.
All official profiles: Facebook, Twitter, LinkedIn, Instagram, YouTube, Wikipedia, GitHub, etc.
Technically yes, but products normally use other properties. sameAs is better suited for Organisation and Person.
Check the structured data report in Search Console or use the Rich Results Test. There may be no direct visual, but the Knowledge Graph improves.
