Named entity · Knowledge Graph entity
An entity is a uniquely identifiable object, such as a person, a brand, a place or a concept, distinct from the character string that names it. LLMs reason in entities and relationships rather than keywords, which makes a consistent, verifiable brand identity essential.
Standalone definition · 43 words
How do engines recognize an entity?
They link mentions of a name to a unique identifier, relying on knowledge graphs and reference sources such as Wikipedia or Wikidata. Organization or Person markup with sameAs, a clear About page and consistent mentions on third-party sources help remove ambiguity.
Why does the entity matter for GEO?
An LLM that cannot tell your brand from a namesake can neither cite nor recommend it correctly. Consistent information (name, description, executives, official links) between the site and third-party sources reduces this risk.
How do you strengthen your entity?
Declare Organization with sameAs pointing to official profiles, identify authors with a dedicated page, harmonize the brand description everywhere and earn mentions in reference sources. Then check what AI engines answer to “what is [brand]?”.
Frequently asked questions
Do I need a Wikipedia page?
It is not required. Wikipedia and Wikidata are common reference sources for knowledge graphs; failing that, reliable third-party sources count.
What is the difference between an entity and a keyword?
A keyword is a character string. An entity is the object it designates: several keywords can point to the same entity.
How do you measure the strength of an entity?
Query several AI engines about the brand, check the Knowledge Panel and answer consistency, and track third-party mentions. There is no official score.
