What is Entity?

Entity
An entity, in search and AI terms, is a distinct thing an engine can identify and store facts about, such as a company, a person or a product, as opposed to a page that merely mentions it. Establishing a business as an entity means giving engines a stable identifier, consistent naming, and verifiable links to the same business elsewhere, so answers about it can be assembled with confidence.

01 In practice

The practical failure this prevents is conflation. Two businesses sharing a name, or one business described inconsistently across its own pages, give an engine no basis to keep them apart, and being merged with another company is materially worse than being unknown.

In markup, this is an Organization node with a stable @id that other nodes reference, plus sameAs links to profiles that independently confirm the same business. Those links are the evidence; the schema without them is an assertion.
