Entity SEO

Google's search engine does not just match keywords to documents. It maps the world. People, organisations, places, concepts and products are all entities in a knowledge graph, each with attributes and relationships to other entities.

When Google confidently knows what your brand is (its category, its founders, its relationship to other known entities) it can connect content, reviews and mentions about you to the right thing. Entity recognition is the difference between "a domain that publishes SEO content" and "the site that runs that SEO curriculum people search for." Entity SEO is how you help search engines and AI assistants make that connection.

Why entity recognition matters#

• Knowledge panels can appear for recognised entities, with your logo, description and official profiles. Google generates them automatically; you cannot buy or force one.
• Author attribution. When authors are clearly identified across publications, their body of work can be connected, which supports the experience and expertise that E-E-A-T is about.
• AI answers. AI assistants describe and recommend brands based on what is written about them across the web. A brand with a clear, consistent identity is easier to describe accurately. (No AI vendor publishes how entity strength affects citation, so treat this as reasoned opinion rather than a measured effect.)
• Disambiguation. When Google clearly understands your entity, content about you is attributed to you, not to a similarly named company.

How Google builds entity understanding#

Google does not publish a full list of Knowledge Graph inputs. Its knowledge panel help says the information comes from various sources across the web, and its structured data docs say some Organization properties are used "behind the scenes to disambiguate your organization". In practice the signals that matter are:

1. Structured data on your site: schema.org markup that states entity facts directly
2. Public knowledge bases such as Wikipedia and Wikidata
3. Authoritative third-party mentions: consistent coverage in trusted publications
4. Co-occurrence: your name appearing alongside related, known entities
5. Official profiles and Google properties: Business Profile for local businesses, YouTube, verified social accounts

Step 1: Assert your identity with schema.org#

Add Organization (or Person, for an individual) markup to your homepage or about page. Google says there are no required properties and recommends adding as many relevant ones as apply. The sameAs property is the key for entity work:

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "@id": "https://example.com/#organization",
  "name": "Example Co",
  "legalName": "Example Co Ltd",
  "url": "https://example.com",
  "logo": "https://example.com/logo.png",
  "description": "Example Co makes open-source analytics tools for small online stores.",
  "foundingDate": "2024-03-01",
  "sameAs": [
    "https://www.linkedin.com/company/example-co",
    "https://www.youtube.com/@exampleco",
    "https://github.com/example-co",
    "https://www.wikidata.org/wiki/Q00000000"
  ]
}

The sameAs array says "this entity is the same thing as these profiles". The stable @id lets other markup on your site (articles, products, people) point back to the same node. Only list profiles you actually control, and keep the name, logo and description consistent everywhere. Organization markup can also influence which logo Google shows in Search results and in your knowledge panel.

Step 2: Wikidata, if you qualify#

Wikidata is the structured database behind Wikipedia. Its bar is lower than Wikipedia's but it is not zero: under Wikidata's notability policy an item needs a valid Wikimedia sitelink, or must be "a clearly identifiable conceptual or material entity that can be described using serious and publicly available references", or must meet a structural need. Self-promotional items with no references get deleted.

If you qualify:

1. Log in at wikidata.org.
2. Create an item for your organisation.
3. Add statements with references: instance of (for example business), official website, inception, country, and identifiers for your official profiles.
4. Link the Wikipedia article if one exists.

Wikidata is a public, widely reused source of entity facts, which is why it is worth getting right. Google has not documented how much weight it gives Wikidata, so do not expect an item alone to produce a knowledge panel.

Step 3: Wikipedia (only if eligible)#

Wikipedia requires notability: significant coverage in independent, reliable secondary sources. If your organisation or the people behind it meet that bar, an article written by independent editors is a strong entity source.

Building author entity signals#

If your site publishes under named authors, make each one an unambiguous entity:

• Consistent name across all publications: "Jane Smith" everywhere, not "J. Smith" in some places.
• An author page on your site with a bio, credentials, photo and links to their other work and profiles.
• Person markup on author pages with sameAs links to LinkedIn, ORCID, Google Scholar or industry profiles, and author on articles pointing to that person's @id or URL.
• Guest bylines in recognised publications in your niche, linking back to the author page.

rel="author" links are not the mechanism here: Google stopped using authorship markup in 2014. Clear bylines, author pages and Person markup are what you control today.

Knowledge panels and Search profiles#

Claiming a knowledge panel. If a panel already shows for your entity:

1. Search for your entity on Google and find the panel.
2. Click "Claim this knowledge panel" at the bottom.
3. Verify by signing in to one of the official profiles Google lists, such as YouTube, Search Console, X (Twitter) or Facebook.

Verified owners can suggest changes and add other representatives. Google reviews suggestions; it does not simply accept what you claim. Not every panel is claimable, and local businesses should manage their information through a Google Business Profile instead.

Search profiles (new in June 2026). On 2026-06-04 Google launched Search profiles for publishers and creators: a shareable profile in Search with an avatar, bio, website, social and video accounts and recent posts. Eligibility is limited to publishers and creators with "a sizable following on at least one major social or video platform", and it launched in the US first. Google says claiming a profile "may trigger the creation of a knowledge panel for eligible publishers and creators", and an existing panel gets the updated avatar, latest content and a profile link. If you are a publisher or creator who qualifies, claim it.

Entities and AI answers#

This is where entity SEO connects to GEO. AI assistants answer questions about brands from two places: what their models learned in training, and what they retrieve from the web at answer time (AI Overviews and AI Mode use Google's index; ChatGPT, Claude and Perplexity run their own search crawlers alongside other search partners). Both reward the same thing: a consistent, well-documented identity across independent sources.

Two cautions from Google's May 2026 AI optimization guide:

• No special markup is needed for AI Overviews or AI Mode. Organization markup helps disambiguation; it is not an AI ranking switch.
• Inauthentic mentions do not help. Google lists "seeking inauthentic 'mentions' across the web" among tactics to ignore, and its spam policies have explicitly covered attempts to manipulate generative AI responses since 2026-05-15.

Real coverage, reviews, community discussion (Reddit, Forums & Communities) and digital PR build entity understanding. Bought or fabricated mentions are policy risk.

Measuring entity recognition#

Entity SEO is slow work. But once Google and AI assistants confidently understand your brand and authors, that understanding carries across everything you publish, and it is hard for competitors to copy.
