On May 16, 2012, Amit Singhal, then Google's senior vice president of engineering, described a change in four words: "things, not strings." Search would stop matching letters and start recognizing the people, places, and businesses behind them. Fourteen years later, that idea decides whether Google, and the AI tools built on it, can describe your business correctly. Entity SEO is the work of making sure they can.
Quick answer
Entity SEO means helping search engines and AI tools recognize your business as one clear "thing" with consistent facts: name, location, services, people, and profiles. Google's Knowledge Graph has worked on "things, not strings" since 2012. Build a strong About page, Organization schema with sameAs links, consistent listings and mentions, and test whether Google and AI assistants recognize you.
Most entity advice is written for publishers and global brands. This guide is for businesses with a name, a few locations, and a reputation to protect: what an entity is, how Google and AI assistants use them, five steps to make your business unmistakable, and how to check whether it's working.
What is an entity in SEO?
An entity is a single, clearly defined thing that a search engine can recognize and describe: a business, a person, a place, a product, or an idea. Entity SEO is about making your business one of those well-defined things, with facts search engines can trust.
Take a dental practice. The practice is an entity. So is the dentist who owns it, the town it's in, the services it offers (implants, whitening), and the professional association it belongs to. Google doesn't just see the words "dentist in Mesa." It sees a practice, connected to a person, located in a place, offering specific services, with reviews and links that confirm all of it.
In simple words: an entity is a "thing" Google knows about, and its facts are what Google knows about that thing.
Google built this into search with the Knowledge Graph, announced on May 16, 2012. Singhal described it as a model that "understands real-world entities and their relationships to one another: things, not strings." At launch, it held "more than 500 million objects, as well as more than 3.5 billion facts about and relationships between these different objects," drawn from sources such as Wikipedia and Freebase and "tuned based on what people search for, and what we find out on the web."
The last part is what makes entity SEO possible for a small business. Google learns about entities from the web, which means your website, profiles, and mentions are part of what it learns.
- 1OwnerWho runs it: named on the About page
- 2Town or service areaWhere it operates: matches the Business Profile
- 3ServicesWhat it does: one page per service
- 4Business Profile and websiteThe core facts: name, address, phone
- 5Directory and social profilesConfirmation: the same facts, listed in sameAs
- 6Reviews and press mentionsReputation: independent sources
Google has organized search around “things, not strings” since 2012.
Entities vs keywords
Keywords are the words people type; entities are the things those words refer to. Keyword SEO matches pages to phrases. Entity SEO helps Google understand who you are, so it can connect you to any phrase that describes you.
| Keyword approach | Entity approach | |
|---|---|---|
| Focus | The exact words in a query | The business, people and places behind the words |
| Question it answers | "Does this page contain these words?" | "Is this the business the searcher means?" |
| Handles synonyms | Only if you list them | Naturally, because the thing is the same |
| Handles ambiguity | Poorly ("Mercury": planet, car, element?) | By context and connected facts |
| Where it shows | Rankings for specific phrases | Knowledge panels, brand searches, AI answers |
You need both. Keyword research still tells you how customers describe what you do; our keyword research guide covers it, and search intent types show what each query is really asking. Entity work makes sure that when those searches happen, Google knows exactly which business to connect them to.
How Google and AI assistants use entities
Google uses entities to connect facts from many sources into one picture of a business, then uses that picture in knowledge panels, local results, and AI answers. The more consistent your facts, the easier that picture is to build.
Knowledge panels. When Google is confident about an entity, it may show a knowledge panel: the box beside search results with a name, description, logo, key facts, and profile links. For local businesses, the Google Business Profile plays a similar role.
AI Overviews and AI Mode. Here's where much entity advice overreaches. Google's page on AI features and your website, last revised December 10, 2025, says there are "no additional requirements to appear in AI Overviews or AI Mode." It goes further: "There's also no special schema.org structured data that you need to add." Behind the scenes, AI features fire off several related searches at once (Google's name for this is query fan-out) and cite the pages that answer those sub-questions best.
So entity work isn't a key to AI Overviews. What it does is make your business easier to identify correctly when Google's systems, and other AI assistants, gather facts about you. A business whose name, address, services, and people match everywhere is easy to describe. One with three names, two addresses, and conflicting hours is easy to get wrong.
Other AI assistants, such as ChatGPT, build answers from their own search tools and the web pages they can read. Consistent, well-sourced facts help there too. Our guides on getting cited in AI Overviews and ranking in ChatGPT cover each in detail.
Step 1: Build your entity home
Your entity home is one page on your own site that states, clearly and completely, who your business is. For most businesses, it's the About page, and every other profile should point back to it.
Entity home checklist:
- Legal and trading name, exactly as you want it known, with any former names noted
- What you do, in one plain sentence near the top
- Founded date and a short history
- Address or service area, matching your Google Business Profile
- Phone number and email, matching every listing
- Key people: owners and senior staff, with names, roles, and short bios
- Services or products, with links to each service page
- Service areas or locations, with links to each location page
- Credentials: licenses, certifications, memberships and awards you can document
- Official profiles: links to your Business Profile, LinkedIn, Facebook, industry directories and any association listings
A quick test: could a stranger read only this page and correctly answer who owns the business, where it operates, what it does, and how to contact it? If any answer needs a second page, add it here. Many About pages tell a founding story but leave out the address, the owner's name, or the service area, which are exactly the facts machines look for.
Write it for a person first. A clear About page helps customers decide to trust you, and the same clarity helps machines. If you have several locations, keep the About page focused on the business as a whole and give each location its own page.
Step 2: Add Organization and LocalBusiness schema
Schema markup states your key facts in a format machines read directly. Google's documentation on Organization markup, last revised September 8, 2026, says adding it "can help Google better understand your organization's administrative details and disambiguate your organization in search results." For local businesses, Google recommends the most specific LocalBusiness subtype, such as Dentist or Plumber.
Three properties do most of the entity work:
- @id gives your business a permanent identifier, usually your homepage URL plus "#organization," so every page can refer to the same entity.
- sameAs lists your official profiles. Schema.org defines it as the "URL of a reference Web page that unambiguously indicates the item's identity."
- logo gives Google the image to associate with your brand.
Here's a short example for a fictional practice:
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Dentist",
"@id": "https://www.brightsidedental.example/#organization",
"name": "Brightside Dental",
"url": "https://www.brightsidedental.example/",
"logo": "https://www.brightsidedental.example/logo.png",
"telephone": "+1-480-555-0142",
"address": {
"@type": "PostalAddress",
"streetAddress": "120 W Main St",
"addressLocality": "Mesa",
"addressRegion": "AZ",
"postalCode": "85201"
},
"sameAs": [
"https://www.facebook.com/brightsidedentalmesa",
"https://www.linkedin.com/company/brightside-dental"
]
}
</script>Keep sameAs to profiles you control or that clearly describe your business. Every link should point to the same entity.
A note on expectations: schema helps Google understand your business, but it isn't a ranking switch, and Google says no special markup is needed for AI features. Treat it as making your facts explicit, not as a shortcut.
Step 3: Make your facts consistent everywhere
Consistency is the core of entity SEO. Google confirms an entity by seeing the same facts across many independent sources, so every mismatch weakens the picture.
Check these sources, in this order:
- Google Business Profile: name, address, phone, hours, primary category, description and website link
- Your own website: footer, contact page, About page and schema
- Major directories: Apple Business Connect, Bing Places, Yelp and the leading directories in your trade
- Social profiles: Facebook, LinkedIn, Instagram and any others you use
- Industry associations and licensing bodies: member listings and license lookups
- Press and partner pages: articles and supplier listings that describe you
What to match: the exact business name, address formatting, phone number, website URL, categories and a short description. Small differences add up. "Brightside Dental," "Brightside Dental Care LLC" and "Bright Side Dentistry" might look like three businesses to a machine.
When you find old addresses or former names, update them where you can, and mention former names on your About page so the history is clear. Work through the profile itself with our Business Profile checklist, and if it won't show up at all, see why a profile goes missing from Maps.
Step 4: Earn mentions that connect your brand to your topics
Mentions on other sites tell Google what your business is known for. The most useful ones pair your name with your services and your location, on sites people trust.
Good sources of entity-building mentions:
- Local press: a feature on your new location, a community project or expert comments on a local issue
- Partners and suppliers: manufacturer "certified installer" pages, distributor listings, referral partners
- Associations: member directories and award listings in your trade
- Reviews: customers describing the service they received, in their own words
- Expert quotes: commentary for trade publications or local outlets, with your name and title
Earn them; don't buy them. Google's spam policies treat paid or exchanged links meant to manipulate rankings as link spam. Genuine mentions also carry more weight with customers.
A note on Wikidata. Some entity guides recommend creating a Wikidata item for your business. Only do this if your business genuinely qualifies. Wikidata's notability policy accepts items that describe "a clearly identifiable conceptual or material entity that can be described using serious and publicly available references," among other criteria. Self-promotional items without independent references are likely to be deleted, and a deleted item helps no one.
Step 5: Test whether Google and AI recognize you
You can check entity recognition in a few minutes. Run these tests now, then repeat them monthly.
Search your brand name. Search your exact business name and see what appears. A Business Profile or knowledge panel showing correct facts is a strong sign. If the panel is a knowledge panel rather than a Business Profile, look for a "Claim this knowledge panel" option. Google's knowledge panel help notes that "Not all knowledge panels are claimable as of now," so check back periodically.
Look yourself up in the Knowledge Graph. Google's Knowledge Graph Search API lets you search for an entity by name and see whether Google returns a match. It's a quick diagnostic for technical users. Google itself warns that the API "is not suitable for use as a production-critical service," so treat results as a hint, not a verdict.
Ask AI assistants. Try prompts such as:
- "What is [business name] and where is it based?"
- "What services does [business name] offer?"
- "Who owns [business name]?"
Record each answer, note any wrong facts, then trace them to their likely source: an outdated directory, an old address or a confusing name.
Entity SEO myths
Several popular claims about entity SEO don't hold up against what Google actually says.
Myths to ignore:
"Entity SEO is just schema." Schema states your facts; consistency across independent sources and real mentions confirm them. Markup alone can't make a business well known.
"You need special markup for AI Overviews." Google says, "There's also no special schema.org structured data that you need to add."
"More sameAs links are always better." Schema.org defines sameAs as a page that "unambiguously indicates the item's identity." Links to weak or unrelated profiles add confusion, not strength.
"A knowledge panel can be bought." Knowledge panels are generated automatically from information Google finds. You can claim and suggest edits to some panels, but not purchase one.
How long entity work takes and how to measure it
There's no fixed timeline. Profile and schema fixes can be picked up as soon as Google recrawls them, while reputation built through mentions grows over months.
Track three things:
- Brand search results: whether a correct Business Profile or knowledge panel appears for your name
- Branded search impressions in Search Console, filtered to queries containing your business name
- AI assistant answers to the same set of prompts each month, with errors noted

Entity SEO FAQs
What is an entity in SEO?
An entity is a single, clearly defined thing a search engine can recognize, such as a business, person, place or product. Google has organized information around entities since launching its Knowledge Graph in 2012. Entity SEO helps Google and AI tools recognize your business and connect the right facts to it.
What is an example of an entity in SEO?
A local dental practice is an entity. So are its owner, its town, and its services. Google connects them: this practice, owned by this dentist, located in this town, offering implants and whitening. Consistent facts on the website, Business Profile, and directories confirm those connections.
Is entity SEO the same as semantic SEO?
They overlap but aren't the same. Semantic SEO is about covering a topic's meaning and related concepts in your content. Entity SEO focuses on making specific things, especially your business, clearly identifiable with consistent facts. Good content usually does both.
Do I need schema markup to appear in AI Overviews?
No. Google's AI features documentation says, "There's also no special schema.org structured data that you need to add." Indexing and snippet eligibility are what count. Organization schema still helps Google understand your business details, so it's useful, but it isn't required for AI features.
How do I get a Google knowledge panel for my business?
You can't request or buy one; Google generates panels when it's confident about an entity. Local businesses usually get a Business Profile instead, which you can claim and manage. Build a clear About page, consistent listings, and genuine mentions, then check whether a panel appears and is claimable.
