Entity SEO

Google's search engine doesn't just match keywords to documents. It maps the world. People, organisations, places, concepts, products - all of these are entities in a knowledge graph. Each entity has attributes, relationships to other entities, and a confidence score measuring how well Google understands what it is.

When Google confidently knows what your brand is - its category, its founders, its relationship to other known entities - it treats your content differently. Entity recognition is the difference between "a domain that produces SEO content" and "the site that runs that SEO curriculum people search for." The second one ranks better, gets cited by AI, and earns Knowledge Panels. Entity SEO is how you get there.

Why entity recognition changes everything#

• Knowledge Panels appear in search results for recognised entities - a prominent trust signal that competitors without entity status can't replicate
• Author attribution - recognised authors get their body of work linked together across publications; their expertise signals carry across sites
• AI citations - LLMs are substantially more likely to cite sources they have strong entity associations for; the model "knows" who you are
• Disambiguation - when Google clearly understands your entity, content about you gets correctly attributed to you, not to a similarly-named competitor

How Google builds entity understanding#

The Knowledge Graph assembles its picture of each entity from multiple sources:

1. Structured data on your site - schema.org markup that asserts entity facts directly
2. Wikipedia and Wikidata - the highest-authority source for entity facts in the entire graph
3. Authoritative third-party mentions - consistent mentions of your entity in trusted publications
4. Semantic co-occurrence - entities that consistently appear alongside known entities absorb some of their associations
5. Your Google properties - Google Business Profile, YouTube channel, Google Scholar - these connect directly to the Knowledge Graph

Step 1: Assert your identity with schema.org#

Add Organization or Person schema to your site with complete, consistent attributes. The sameAs property is the key:

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "SEO101",
  "url": "https://seo101.dev",
  "logo": "https://seo101.dev/icon.svg",
  "description": "A free, in-depth curriculum for learning SEO, AEO, and GEO.",
  "sameAs": [
    "https://twitter.com/seo101",
    "https://www.linkedin.com/company/seo101",
    "https://www.wikidata.org/wiki/Q12345678",
    "https://github.com/seo101"
  ]
}

The sameAs array tells Google: "this entity is the same thing as these profiles across the web." Google merges signals from all of those profiles into a single entity node - building a richer, more confident picture of what you are.

Step 2: Get on Wikidata#

Wikidata is the structured data layer beneath Wikipedia - and unlike Wikipedia, it has no notability threshold for most entity types. Any organisation can have a Wikidata entry.

How to create one:

1. Log in at wikidata.org (or create a free account)
2. Create a new item for your organisation
3. Add statements: instance of → organisation; official website → your URL; official logo image → uploaded file; country → your location
4. If you have a Wikipedia article, link it here (described by source → the Wikipedia article)

A Wikidata entry with your URL listed as official website is one of the strongest entity signals you can create - it's a direct assertion in the same structured database that feeds Google's Knowledge Graph.

Step 3: Wikipedia (if eligible)#

Wikipedia requires notability: independent, reliable secondary sources that cover the subject in significant depth. If your organisation or the people behind it meet that bar, a Wikipedia article is the highest-authority entity signal available.

For individuals: academic publications, substantial press coverage in major outlets, or recognised industry awards typically qualify. For organisations: coverage in multiple major publications, industry significance, or historical importance.

Building author entity signals#

If your site publishes content under named authors, their entity status transfers to your site's E-E-A-T:

• Consistent name across all publications - "Jane Smith" everywhere, not "J. Smith" in some places and "Jane S." in others
• rel="author" on guest posts pointing back to the author's profile page on your primary domain
• schema.org/Person on author profile pages with sameAs links to LinkedIn, Google Scholar, ORCID, industry organisation profiles
• Guest bylines in recognised publications in your niche - each one adds an authoritative mention in Google's entity graph

An author who's cited by name in authoritative sources becomes a recognised person entity - and recognised people's content is weighted differently than anonymous content.

Claiming and managing your Knowledge Panel#

If your entity is recognised, Google may surface a Knowledge Panel in search results for your brand name. To claim it:

1. Search for your brand in Google
2. If a Knowledge Panel appears, scroll to the bottom and click "Claim this Knowledge Panel"
3. Verify ownership through a linked profile - typically GSC or a connected social profile

Once claimed, you can suggest corrections to incorrect facts and request updates. Google reviews and approves them - the underlying data comes from Wikipedia, Wikidata, structured data, and web signals, not from what you claim directly.

Entity SEO and LLM training data#

Here's where it connects to GEO: large language models (ChatGPT, Gemini, Claude) are trained on web content. Entities that appear frequently and consistently across authoritative sources are better represented in model weights.

This means entity recognition directly affects:

• Whether a model "knows" your brand when asked about it
• Whether a model cites you when answering questions in your topic area
• Whether AI Overviews mention your brand in relevant results

The overlap with entity SEO is significant: Wikipedia, Wikidata, and authoritative press coverage all contribute to LLM entity representation. Building entity presence for traditional search also builds it for AI.

Measuring entity recognition#

Entity SEO is slow work. But once Google has confident entity recognition for your brand or authors, it compounds across everything they produce - and it's the kind of signal that's very hard for competitors to copy.
