"sameAs" schema property

sameAs is a property (not a schema type itself) that can be applied to many schema types, most commonly Organization, Person, LocalBusiness, or Place. It's one of the most underused but valuable pieces of structured data, because it directly supports entity disambiguation in Google's Knowledge Graph.

What "sameAs" does

sameAs provides a list of URLs that point to authoritative references for the same entity — the same business, person, brand, or place described in other places on the web. It tells search engines: "the entity I'm describing here is the same one referenced at these other URLs."

What to link to

Any profile for the same entity on a 3rd party platform, e.g.

• Government or official registries – ASIC, professional bodies, etc.
• Authoritative third-party platforms – LinkedIn company/profile pages
• Social media profiles – Facebook, X/Twitter, Instagram, etc.
• Industry-specific directories – established speciality directories

Why "sameAs" matters

Search engines build entity understanding by connecting references across the web. Without sameAs, Google has to infer those connections through unstructured signals. With sameAs, you're explicitly drawing the lines connecting the different profiles:

• "This Organization is the same one as this LinkedIn page, this Wikipedia article, this Facebook profile."
• "This Person is the same individual published on this academic profile and this Facebook page."

Strong sameAs signals contribute to Knowledge Graph inclusion and panel accuracy, and reinforce E-E-A-T for authors and brands.

Example: Organization

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Company Name",
  "url": "https://companyname.com.au",
  "sameAs": [
    "https://en.wikipedia.org/wiki/Example_Agency",
    "https://www.wikidata.org/wiki/Q12345",
    "https://www.linkedin.com/company/companyname",
    "https://twitter.com/companyname",
    "https://www.facebook.com/companyname"
  ]
}

Example: Person

{
  "@context": "https://schema.org",
  "@type": "Person",
  "name": "Jane Author",
  "sameAs": [
    "https://www.linkedin.com/in/janeauthor",
    "https://twitter.com/janeauthor"
  ]
}

SEO value

• Major contributor to Knowledge Graph inclusion and entity confidence
• Strengthens branded search and knowledge panel accuracy
• Reinforces an author's authority for E-E-A-T
• Helps disambiguate entities with similar names (e.g., multiple businesses or people sharing a common name)

Best practices

• Only list profiles that are genuinely yours and actively maintained
• Use the canonical, public URL for each profile (not redirect URLs)
• Keep the list reciprocal where possible — your LinkedIn should link back to your site, etc.
• You don't need sameAs on every page; declaring it once on a primary entity node (home or about) is sufficient.
