Entity SEO.
The Complete
Guide.

Entities are the grammar of modern search. Without strong entity representation, your brand is a string of characters the engine doesn't know what to do with. Here's how to fix that.

TL;DR

Entities are the things — brands, people, places, products, concepts — that search engines and LLMs track in their knowledge graphs. Entity SEO is the work of making sure your brand, your people and your products are clearly represented as distinct, disambiguated entities that engines can confidently cite.

What an entity actually is

In search and LLM systems, an entity is a thing that has been identified and assigned a stable identifier in a knowledge graph. Google has its Knowledge Graph. Wikidata has Q-numbers. LLM training pipelines build their own internal entity representations by clustering references across their corpus. The common point: entities are how these systems reason about the world. "Apple" is not a word — it's (at least) three entities: the fruit, the tech company, and the record label. Which entity the system thinks the user means is what determines the answer.

Your brand is an entity too. The question is: is it a strong, disambiguated entity that the engines confidently know about — or is it an ambiguous string that gets confused with similar names, missed in citations, and occasionally hallucinated into something you never claimed?

Why this matters for GEO

Every generative engine filters citation candidates through entity recognition. If the engine isn't confident which entity a page is about, it won't cite the page — because citing the wrong entity is worse than not citing at all. Brands with weak entity presence effectively self-disqualify from citations. The fix is entity reinforcement: across the open web, across your own site, and across the knowledge graphs the engines rely on.

Step 1 — Wikidata

Wikidata is the most important single entity source for every LLM we've measured. It's the structured data layer Wikipedia sits on top of. Every mainstream AI engine's training pipeline ingests it. If your brand doesn't have a Wikidata item, that's the single highest-leverage fix you can make. Creating one is free and takes an editor about an hour. The Wikidata community has rules about notability — brands need to demonstrate coverage in reliable third-party sources before an item sticks. If your brand doesn't yet meet notability, that's a PR problem to solve before the entity problem.

Step 2 — Wikipedia

If your brand is notable enough for Wikipedia, get a Wikipedia article. Notability here is strict: multiple, independent, reliable sources must have covered your brand substantively. A Wikipedia article massively reinforces entity strength across every engine — it's the single biggest lever available after Wikidata.

Step 3 — Your own site: entity coherence

Every mention of your brand on your own site should use the same phrasing, the same capitalization, the same disambiguating context. Schema Organization blocks should include sameAs links to your Wikidata item, LinkedIn, Crunchbase, GitHub, and other stable external profiles. Every service page should reference the Organization by @id. This is the boring, high-compounding work that most teams never finish.

Step 4 — External entity reinforcement

Industry directories, major publication profiles, conference speaker pages, podcast guest archives — every external mention of your brand that uses consistent phrasing strengthens the entity. Inconsistent phrasing (sometimes "Acme Corp", sometimes "Acme", sometimes "Acme Agency") dilutes it. The fix is editorial discipline — train every team that publishes on your brand's behalf to use the canonical form.

How to know if entity work is paying off

Two signals. First, entity disambiguation in search: try "brand name" + ambiguous context in Google and see whether the knowledge panel shows the right entity. Second, LLM citations: run your prompt panel and see whether the brand is named confidently and consistently across engines. Strong entities get cited cleanly. Weak entities get missed, or worse, confused with something else.

FAQ

Common questions.

Do I need a Wikipedia article to do GEO?+

No, but it helps enormously if you can get one legitimately. A Wikidata item is more achievable and still provides substantial entity reinforcement.

How long does entity work take to show up in LLM citations?+

Wikidata changes can affect live-browse engines like Perplexity within weeks. Training-cycle engines (ChatGPT, Claude, Gemini) show effects only after the next model update, which can be months.

Can I just create my own Wikipedia article?+

Technically yes, but the community aggressively removes articles that look like self-promotion. It's far better to earn coverage in independent reliable sources first, then let editors create the article naturally.
