**An Organization or Person entity with sameAs links is how you tell engines who you are and connect your site to your verified profiles across the web.** This check looks for entity schema that names your organisation or person and links out (via sameAs) to your authoritative profiles — Wikipedia, LinkedIn, social accounts — so engines can confidently build a knowledge graph around you.
It checks whether your page defines who you are as an entity and connects that identity to the wider web. Specifically:
- Entity schema — an Organization or Person type that names and describes you.
- sameAs links — sameAs properties pointing to your verified profiles (Wikipedia, LinkedIn, X, official directories).
- Consistency — whether the entity details are complete and match your identity across those profiles.
An entity schema with verified sameAs profile links passes; an entity present but with no sameAs is a warning; no entity schema at all is a fail.
GEObubbly checks for Organization or Person schema and whether it includes sameAs links to authoritative profiles. It's a core, scored Structured Data check that runs directly against the page's markup.
Modern search and AI engines think in terms of entities — distinct things like your company or an author — not just keywords. Declaring an Organization or Person schema names your entity explicitly and describes it (name, logo, URL, founding details, contact points). The sameAs property then links that entity to its authoritative presence elsewhere: your Wikipedia page, LinkedIn, X/Twitter, Crunchbase, official directories. This matters because it lets engines disambiguate and verify you — confirming that the company on your site is the same one with these recognised profiles — which is how a knowledge graph (and a Google knowledge panel) gets built with confidence. For GEO this is especially powerful: when an AI engine needs to attribute information to a trustworthy entity, a clearly-defined organisation or person with verified sameAs links is far easier to cite accurately than an anonymous site.
Organization and Person schema are schema.org types that explicitly declare who an entity is in machine-readable form. Organization markup names a company and can include its logo, URL, contact points, founding date and more; Person markup does the same for an individual, such as an author. Adding this schema tells engines that a specific entity exists and gives them structured facts about it, rather than leaving them to infer your identity from page text. It's the foundation of entity SEO and a prerequisite for engines building a confident knowledge graph or knowledge panel about you.
The sameAs property links your declared entity to its authoritative profiles elsewhere on the web — your Wikipedia page, LinkedIn, X/Twitter, Crunchbase, official directories and similar. It tells engines that the organisation or person described in your schema is the same entity represented by those external profiles, which lets them disambiguate and verify your identity with confidence. This cross-referencing is central to how knowledge graphs are built: the more your entity is consistently linked to recognised sources, the more confidently engines can attribute and surface information about you.
A Google knowledge panel is built from the entity information engines can confidently associate with you, and Organization or Person schema with sameAs links gives them exactly that: a clear declaration of who you are plus verified connections to authoritative profiles. While schema alone doesn't guarantee a panel — Google also draws on external signals — providing accurate, consistent entity markup makes it far easier for it to recognise and represent your entity correctly. It's one of the most direct on-site steps toward being treated as a distinct, verified entity in search.
Yes, significantly. AI answer engines attribute information to entities, so a clearly-defined organisation or person — named in schema and verified through sameAs links to recognised profiles — is much easier for them to identify and cite accurately than an anonymous site. The structured identity reduces ambiguity about who is responsible for the content, which supports trustworthy attribution. As AI search grows, having a well-defined, verifiable entity is becoming an important GEO advantage, reinforcing the expertise and authority signals engines look for.
Link to the authoritative, verified profiles that genuinely represent your entity: your Wikipedia or Wikidata entry if you have one, official social accounts (LinkedIn, X/Twitter, Facebook, YouTube), industry directories like Crunchbase, and any other recognised pages clearly associated with you. The goal is quality and accuracy, not quantity — link only to profiles you actually control or that authoritatively describe you, and keep the details consistent across them. Reliable, consistent connections are what let engines verify your identity; spurious or mismatched links undermine that trust.
