Entity.
An entity means a distinct thing that search and answer engines recognise — a person, an organisation, a place, a product or a concept.
Search engines moved from words to entities long ago. A query is now answered not by matching text alone but by working out which entity it is about. Answer engines take that logic further: when producing an answer they infer from entity links which source is authoritative on which subject.
The practical consequence is this: a site comes to be regarded as expert on a subject not by using that word often but by being recognised as an entity related to it.
Recognising an entity depends on three questions being answered: who, what do they know, what are they related to. All three can be declared with structured data, and all three are missing on most sites.
- Identity — name, type, contact, logo, founder.
- Expertise — which subjects it claims authority on.
- Relations — which content, services, projects and external profiles it is tied to.
The most common mistake is making separate, unlinked identity declarations on every page; machines then cannot tell whether these are ten organisations or ten declarations of one. The correct pattern is to define the identity once and refer to it from everywhere.
And a rule of honesty: a claim of expertise with nothing behind it works against you, because it contradicts the rest of the site.
An entity existing only on its own site means there is a single source about that entity — and models treat single-source information cautiously. The same identity appearing in the same form elsewhere provides independent corroboration.
That is why the final layer of entity architecture lives off-site: profiles, directory records, third-party mentions. It is the hardest layer to build and the most impossible to hurry.
- Identity — name, type, contact, logo, founder. Defined once, referred to from everywhere.
- Expertise — which subjects it claims authority on. A claim with nothing behind it is not written.
- Content links — articles, services, projects; all tied to the identity.
- External profiles — a verifiable presence on other platforms.
- Reciprocity — the profile must point back to the site; a one-way link cannot be verified.
The last item is critical: a declaration is a claim, and a verifiable one. The machine opens the link and looks there for a pointer back to you — without reciprocity the claim is not verified.
