Named Entities: The Foundation of Semantic SEO
8 min
Google and LLMs reason through entities — people, places, organizations, concepts, products — rather than isolated keywords. Integrating relevant named entities into your content and structured data reinforces topical authority and semantic readability. It is the foundation of modern SEO and GEO.
SEO in the 2010s meant repeating keywords. SEO in 2026 means talking about the right entities, in the right context, with the right relationships. Google and LLMs now understand meaning, not just terms. Here is how to take advantage of it.
What is an entity in Google's sense?
An entity is a real-world object — or a concept — that can be clearly identified and distinguished from other similar objects. For Google, an entity has a name, attributes, relationships with other entities, and often a listing in the Knowledge Graph.
The main entity categories relevant to SEO are: people (founders, experts, authors), organizations (companies, institutions), places (cities, countries), products and services, and concepts (disciplines, techniques, theories).
How Google uses entities to understand your content
When Google analyzes your page, it identifies the mentioned entities and connects them. This analysis allows it to understand the topic covered beyond keywords, assess relevance to a query, and associate your domain with thematic entities.
Content that mentions the right entities — recognized industry tools, domain experts, reference organizations — sends topical relevance signals that keywords alone cannot convey.
Pages mentioning entities recognized in the Google Knowledge Graph achieve on average 25 to 40% more positions on semantically related queries, compared to pages without identifiable entities.

Integrating named entities into your content
Start by identifying the central entities of your topic. For an SEO agency, these are Google algorithms (Panda, Penguin, Helpful Content Update), tools (Semrush, Ahrefs, Google Search Console), concepts (E-E-A-T, Core Web Vitals), and recognized experts.
Mention these entities naturally in your content, using their exact names. Avoid approximate paraphrases: if you are talking about Google Search Console, do not call it 'Google's tool' — name it.
- Use official and exact names of cited tools, platforms, and organizations.
- Cite domain experts by name, with their title or affiliation.
- Mention dates and versions when they qualify an entity (Helpful Content update, Core Web Vitals 2025).
- Link your main entities to their reference pages (Wikipedia, official site) to help Google disambiguate.
Entities and structured data: the Knowledge Graph connection
Organization, Person, and Product structured data allow you to explicitly declare the entities associated with your site and its authors. This is the most direct way to establish a connection between your domain and Google Knowledge Graph entities.
An author with a complete Person schema, linked to their Wikipedia or Wikidata profile, is a recognized entity. A site with an Organization schema including its Wikidata identifier is an entity anchored in the Knowledge Graph. This recognition increases LLMs' trust in your content.
FAQ
Should synonyms be avoided to optimize entities?
Not necessarily. Synonyms and natural variations are understood by modern LLMs. What matters is that the exact entity name appears at least once in an unambiguous context, and that the variations used afterward are consistent.
Do local entities matter for local SEO?
Yes, and significantly. Mentioning places, neighborhoods, local events, or regional organizations reinforces the local anchoring of your content. It is a lever often underused to improve local visibility on geo-targeted queries.
How do you find relevant entities for your sector?
Analyze the best-ranked pages on your target queries and identify the common entities they mention. The Google NLP API (publicly available) allows automatic entity extraction from a page. It is an effective starting point for a semantic audit.
