Named entity

A named entity is a uniquely identifiable real-world object — a person, brand, place, organization, product, or concept — that search engines and large language models recognize, disambiguate, and connect to a knowledge graph. Unlike a simple keyword, an entity has a stable identity, attributes, and relationships with other entities. In SEO and GEO, entity-based optimization means helping Google and generative AI understand who or what your content describes, rather than just the character strings it contains. This named entity recognition (NER) powers Google's Knowledge Graph, AI Overviews, and answers from ChatGPT, Perplexity, or Gemini. A brand properly established as an entity — consistent in naming, attributes, and citations — becomes easier for LLMs to cite and builds stronger topical authority. Entity optimization is now foundational to any modern visibility strategy.

A named entity is the fundamental unit through which search engines and generative AI understand the world. Rather than manipulating isolated words, Google and LLMs reason in terms of identifiable objects: a person, an organization, a place, a product, or an abstract concept.

How it works

Named Entity Recognition (NER) is a natural language processing task that detects these objects in a text and then disambiguates them. When you write "Apple," the system has to decide whether it means the technology brand or the fruit. To do so, it relies on context, on associated attributes, and on known relationships within the Knowledge Graph. Once the entity is identified and tied to a unique identifier, the engine can attach facts, citations, and neighboring entities to it.

Why it matters in GEO

In 2026, generative engines do not cite keywords: they cite entities they trust. A brand clearly established as an entity — consistent naming, explicit attributes, presence on reference graphs — becomes a natural candidate for AI Overviews and answers from ChatGPT or Perplexity.

A retenir

Optimizing for entities means helping machines understand who you are, not just which words you use.

A concrete example

An agency that wants to be cited as an expert must consolidate its entity: a unique, distinctive name, consistent structured data, a Wikidata record, and uniform mentions across the web. The denser and more disambiguated the entity, the more it gains in AI citability and topical authority. At LUWIZ, this is the foundation of every generative-search visibility strategy.

FAQ

Frequently asked questions

A keyword is a character string, whereas a named entity is a real object with a stable identity and attributes. Google can recognize the same entity behind several phrasings, which makes entity-based optimization more robust than targeting isolated keywords.

You need consistent naming everywhere, structured data (Organization, Person schema), a presence on Wikidata and reference directories, plus coherent citations. The more your brand is disambiguated and linked to known entities, the more confidently AI engines cite it.
