What Is Entity Based SEO? Best Free Guide for Local Business
What is entity based SEO and how does it work?
Entity SEO is a search optimization strategy that focuses on distinct, well-defined things (people, places, organizations, products or concepts) and the relationships between them, rather than relying only on isolated keywords. In practice, entity based SEO means building your pages around the things Google can identify, not only around the words people type. An entity is a real thing with its own identity: a business, a service, a city, a brand, a person or a certification. Google connects these things in its Knowledge Graph and uses them to understand what a page is really about.
For a local business this is very practical. An HVAC page that clearly names the services, the equipment, the problems it fixes, the cities it serves and the licenses it holds gives Google far more to work with than a page that repeats "AC repair near me" ten times.
This guide explains what entities are, how entity based SEO differs from keyword SEO, how to find the entities your competitors cover and you miss, and how to add them the right way with the free SEO entities checker.
Key takeaways
- An entity is a uniquely identifiable thing: a business, service, place, brand, person or credential.
- Entity based SEO makes those things clear in your copy, headings, internal links and schema.
- Keywords bring the match. Entities prove the page understands the topic.
- The fastest way to find gaps is to compare your pages with competitor pages of the same type.
- An entity SEO tool crawls your site and up to 5 competitors and lists the entities you are missing.
What Is Entity SEO? The Simple Definition
Entity SEO is a search optimization strategy that focuses on distinct, well-defined things (people, places, organizations, products or concepts) and the relationships between them, rather than relying only on isolated keywords. In other words, it makes the real things your page is about easy for search engines to identify and connect. Instead of only asking "which keyword does this page target?", you also ask "which things does this page talk about, and are they clear?"
Google moved in this direction years ago. Its Knowledge Graph stores billions of facts about entities and how they relate. Google described the shift as moving from strings to things: understanding what a word refers to, not only matching the letters.
What Is an Entity in SEO? Fast Examples
An entity in SEO is anything that is singular, unique, well defined and distinguishable. A word can be ambiguous. An entity is not. "Mercury" is a word. Mercury the planet, Mercury the element and Freddie Mercury are three different entities.
| Entity type | Local business example |
|---|---|
| Organization | Your business, its brand name |
| Service | AC repair, drain cleaning, teeth whitening |
| Place | Henderson, NV, a neighbourhood, a landmark |
| Product or brand | Carrier, Trane, Invisalign, GAF shingles |
| Credential | NATE certified, licensed plumber, BBB accredited |
| Person | The owner, a named technician, a doctor |
| Thing or concept | Condenser, SEER2, refrigerant leak, slab leak |
How Does Entity Based SEO Work?
Google reads your page, recognizes the entities it mentions, checks how they relate, and compares that with what it knows about the topic. A page that covers the entities searchers and experts expect looks complete. A page that misses them looks thin, even if the keyword is in every heading.
Three things send the strongest entity signals:
- Your page copy. Entities named in real sentences, with context.
- Structured data. JSON-LD that states your business type, services, areas served and profiles. Our schema markup guide covers the local types.
- Links and mentions. Internal links between related pages, plus consistent mentions on other sites like your Business Profile and citations.
How Does Entity Optimisation Differ From Traditional SEO?
Traditional SEO starts with a keyword and fits it into the page. Entity optimisation starts with the topic and makes sure every important thing about it is covered and connected. You still need keywords. Entities are what make the page deserve them.
| Keyword SEO | Entity based SEO | |
|---|---|---|
| Starting point | A search term | The topic and its things |
| Main question | Is the keyword on the page? | Are the right entities on the page? |
| Typical mistake | Keyword stuffing | Name dropping without context |
| Best for | Matching the query | Proving topical depth and trust |
How to Find Entities and the Entity Keyword Gap Free
Compare your pages with the pages that already rank and list the entities they share that you do not. If 3 of your top 5 competitors mention capacitor replacement, a maintenance plan and NATE certification on their AC repair page and you mention none of them, that is your entity gap.
Doing this by hand means reading every competitor page and keeping a spreadsheet. The Local SEO Flow SEO Entities Checker does it in one check: it crawls your site and up to 5 competitors, 30 pages each, sorts pages by type, and shows which services, equipment, problems, places, brands, credentials and semantic words you are missing.

What Is Entity Mapping and Entity Linking in SEO?
Entity mapping is planning which entities belong on which page. Entity linking is connecting them, with internal links between pages and sameAs links in schema to profiles that confirm who you are.
- Home page: business name, main services, service areas, credentials, profiles.
- Service page: the service, its equipment, the problems it solves, brands, warranty.
- City page: the city, neighbourhoods, landmarks and local jobs. Our city pages guide shows the structure.
- About page: owner, team, years in business, licenses and awards.
Entity Based SEO Examples for Local Businesses
Here is how one sentence changes when you write with entities in mind. For example, a plumber's page might say: "We fix leaks fast in your area." An entity rich version says: "Our licensed plumbers find slab leaks with acoustic leak detection and repair them in Henderson and Summerlin, usually the same day."
The second sentence names a credential, a problem, a method and two places. Nothing is stuffed. It simply tells Google and the customer exactly what you do and where.
How to Add Missing Entities the Right Way
- Only add entities that are true for your business.
- Give important services their own section or page.
- Use each entity in the body copy, not only in a menu or heading.
- Add matching schema and check it with the local schema checker.
- Link related pages so the entities connect across your site.
