Entity SEO is the work of making your business easy for search engines to identify as one distinct thing, with clear facts attached, rather than a string of keywords. Google calls these things entities: people, places, organizations and things. This explainer is part of our AI search optimization guide.

Google stores what it knows about entities in its Knowledge Graph and shows a summary in a knowledge panel. For AI search, the payoff is simple. When a tool knows exactly which business you are, it's less likely to mix you up with another.

Key takeaways

  • An entity is a distinct thing search engines can identify: a person, place, organization or thing.
  • Google's knowledge panels are generated automatically from sources across the web.
  • Consistent names, facts and profiles make your business easier to identify.
  • Google hasn't published how its AI features use the Knowledge Graph.

A keyword is a string of text. An entity is the thing the text refers to. "Mercury" could mean a planet, an element or a car brand. Search engines try to work out which one a page or query is about, using context and the facts they already hold.

Your business is an entity too. So are your founders, your products and your location. Each has attributes, such as a name, a website, a logo and a description, and relationships to other entities, such as who founded it or where it operates.

People matter as much as the company. Named authors with real bios, a team page that lists roles and a founder story that matches what other sites say all help connect your business to the people behind it. Anonymous content gives search engines less to connect.

Entity SEO asks one question of every signal you send: does this make it easier, or harder, to tell exactly who we are?

Google's Knowledge Graph and knowledge panels

Google's help pages describe knowledge panels as information boxes that appear when you search for entities in the Knowledge Graph. They give a quick snapshot "based on Google's understanding of available content on the web."

Three details from Google's documentation matter for businesses:

  • Panels are automatic. Google says they are generated automatically, from various sources across the web, sometimes combined with data from partners.
  • Panels update as the web changes. Google also considers feedback from the entity itself and from users.
  • Panels can sometimes be claimed. The subject or an official representative can verify and suggest changes, though not every panel is claimable yet.

A knowledge panel is not the same as a Google Business Profile. Google says Business Profiles are for businesses serving customers at a location or in a service area, and you claim or create those yourself.

Why entities matter for AI answers

Google hasn't published how AI Overviews or AI Mode use the Knowledge Graph, and ChatGPT and Perplexity don't describe any entity system at all. So be wary of anyone who claims to know the exact mechanics.

What is documented points in one direction. Google says its generative AI features are rooted in its core ranking and quality systems, and that they can show what's being said about products and services across the web. Its Organization markup documentation says some properties are used behind the scenes to tell your organization apart from others.

Put plainly: AI tools build answers from what the web says about you. If your name, services and details are consistent everywhere, there's one clear picture to draw from. If they conflict, the answer may blend you with someone else, or repeat an outdated fact.

The entity signals you control

You can't edit the Knowledge Graph directly, but you control most of the sources it learns from. The table below lists the signals worth getting right first.

Entity signals a business controls and where they live
SignalWhere it livesWhat to check
Official nameSite header, footer, About pageOne exact form, used everywhere
DescriptionAbout page, profile biosSame plain summary of what you do
Organization markupHome or About page JSON-LDName, URL, logo, official profiles
Official profilesSocial and professional networksSame name, description and link
Contact detailsContact page, listingsIdentical everywhere they appear
PeopleTeam and author pagesReal names, roles and bios

Start with your own site, because it's the source you fully control. Then work outward to profiles and listings. Markup comes last, because it should describe facts already visible on the page, as covered in structured data for AI search.

What builds entity authority beyond your site

Your own pages say who you are. Other sites confirm it. Coverage in independent publications, mentions in industry directories and references in trusted databases all add to the picture, and they're harder to fake than anything on your own domain.

That's why the next two topics in this guide matter. Brand mentions and citations for AI covers how mentions on other sites shape what AI tools say about you. Wikipedia and Wikidata for brands covers two databases many systems draw on, and the strict rules for businesses that want to appear there.

Avoid shortcuts. Fake profiles, invented reviews and copy-paste directory blasts create conflicting signals, and Google's guidelines warn against misrepresenting who you are in markup. Slow, accurate and consistent wins here.

Common questions

How do I get a knowledge panel for my business?

You can't request one. Google says knowledge panels are generated automatically for entities in its Knowledge Graph, from sources across the web. What you can do is make your business easy to identify: consistent facts on your site and profiles, clear Organization markup and genuine coverage elsewhere. If a panel appears, you may be able to claim it.

Is a knowledge panel the same as a Google Business Profile?

No. Google says they look similar but serve different purposes. A Business Profile is for businesses that serve customers at a location or within a service area, and you claim or create it yourself. A knowledge panel is generated automatically for entities in Google's Knowledge Graph, and you can only claim one that already exists.

Can I edit my business's knowledge panel?

Partly. Google lets the subject or an official representative claim a panel after verifying, then suggest changes. Not every panel is claimable yet. Anyone can also send feedback through the panel itself. Google says panels update automatically as information on the web changes, so fixing the facts at their sources matters as much as the request.
