sameAs (schema.org property)

Definition

sameAs is a schema.org property that links an entity to authoritative external URLs describing the same thing, such as Wikipedia, Wikidata, or verified social profiles. It disambiguates entities for search engines and knowledge graphs, strengthening entity recognition and knowledge panel eligibility.

When you mark up an Organization or Person with structured data, adding sameAs pointers to canonical references tells engines that your entity matches an established record. This resolves ambiguity, joining separate signals about the same brand into one confident node inside a knowledge graph rather than several uncertain fragments.

For AI-visibility work, Acromatico wires sameAs across a client's Wikidata entry, official profiles, and industry directories so generative systems inherit a verified identity. Well-formed sameAs values reduce the chance a model confuses your brand with a similarly named entity, improving the accuracy of any answer that references you.

Questions people ask

What URLs should go in a sameAs array?

Use authoritative, entity-defining pages: Wikipedia, Wikidata, official social profiles, Crunchbase, and reputable industry listings. Avoid low-quality directories or pages you do not control the accuracy of. Every URL should genuinely describe the same entity you are marking up.

Does sameAs guarantee a knowledge panel?

No. sameAs strengthens entity disambiguation and eligibility, but panels also depend on notability, corroborating sources, and engine confidence. It is a meaningful contributing signal, not a switch that forces a knowledge panel to appear on its own.
