What Is sameAs in Schema?

In one sentence

sameAs is a schema.org property that links your entity to its verified profiles elsewhere, telling systems these all refer to the same organisation.

What sameAs means

In practice it's an array of URLs inside your Organization schema — your LinkedIn page, Crunchbase profile, Wikipedia entry, review platform listings, and other verified presences.

It converts scattered mentions into a connected graph. Without it, each profile looks like a potentially separate entity.

Why it matters for AI search

It's one of the highest-return, lowest-effort pieces of entity work available. Ten minutes of markup can materially improve how confidently a model resolves your brand.

It also feeds knowledge panel eligibility, which affects grounding inside Google's ecosystem.

An hour of markup, measurable entity improvement.

This is among the cheapest wins in AI SEO and one of the most commonly skipped, because it's invisible to everyone except the systems that matter.

How to get it right

Building a sameAs graph

  • Inventory every legitimate profile your organisation controls or is listed on
  • Verify each one is actually yours and describes you accurately before linking it
  • Add them as a sameAs array inside your Organization schema
  • Prioritise platforms that get retrieved for your category — review sites for SaaS, directories for services
  • Keep descriptions consistent across every linked profile; contradictions undo the benefit

Common questions

Which profiles should we include?

Verified, active profiles that describe you accurately — LinkedIn, Crunchbase, review platforms, industry directories, Wikipedia if you have an entry.

Quality over quantity. Linking to abandoned or inaccurate profiles works against you.

Does sameAs guarantee a knowledge panel?

No, but it's one of the stronger contributing signals. Panels depend on overall entity confidence across many inputs.

It's necessary rather than sufficient.

Can we link to social profiles?

Yes, and they're commonly included. Just make sure the profile is active and the description matches your canonical one.

An abandoned account with outdated positioning is a liability rather than corroboration.

These come up alongside sameAs constantly.
