Entity SEO and the Knowledge Graph

Entity SEO is the work of making sure search engines and AI systems understand your business as one specific, well-defined thing — a named organisation, in a place, offering particular services, run by particular people — rather than as a collection of words on pages. Google has worked this way since it introduced its Knowledge Graph in 2012 with the phrase "things, not strings". AI answer systems make it more important, because when they describe your business they need to be confident which business they are describing.

For the wider context, see the AI search optimisation guide. This article covers what an entity is, how Google builds its picture of yours, and what a small business can practically do.

What an entity is in SEO

An entity is a distinct thing that can be identified: a person, a business, a place, a product, a concept. "Apple" is a string; Apple the company and apple the fruit are different entities. Google's Knowledge Graph stores entities and the relationships between them — this company is located here, founded by this person, offers these services.

For a small business the problem is usually not famous ambiguity but quiet inconsistency. Your business might appear as "Smith Plumbing", "Smith & Sons Plumbing Ltd" and "Smiths Heating" across your site, Google Business Profile, Companies House, Facebook and three directories, with two different phone numbers. A human works out these are the same business. A machine is less sure, and uncertainty is a reason to cite someone else.

Why entities matter for AI answers

When someone asks an AI tool to recommend an accountant in Rochester, or what a specific firm charges, the system has to connect information from several sources to one business. Clear, consistent entity information makes that straightforward. It is a reasonable inference — not a documented rule from any AI company — that a business described consistently across reputable sources is easier to describe and recommend than one with conflicting details.

Google is explicit about one part of this: its Organization structured data documentation says the markup can help Google understand your organisation's details and disambiguate it in search results. Its AI optimisation guide also points businesses to Google Business Profile and Merchant Center for local and product visibility.

How to strengthen your entity: the practical steps

1. Settle one canonical version of your details. Exact business name, address format, phone number, website URL. Write it down and use it everywhere. Local citations and NAP consistency covers the audit in detail.
2. Complete your Google Business Profile. For local businesses this is the most important entity record you control. Categories, services, hours, service areas and photos. Google Business Profile optimisation goes through it.
3. Write a real About page. Who runs the business, since when, where, what you do and do not do, relevant qualifications or memberships. This is the page Google suggests for Organization markup if it is not on the home page.
4. Add Organization or LocalBusiness structured data. Name, URL, logo, address, telephone, and sameAs links to your official profiles — LinkedIn, Facebook, Companies House listing, industry directories. Make sure everything in it matches the visible page. The schema markup guide covers implementation.
5. Make sure official profiles link back. Your LinkedIn company page, social profiles and directory listings should point to your website, closing the loop.
6. Attach people to the business. If you are the expert, an author page with your background, linked from articles, helps connect your expertise to your business entity.
7. Earn genuine mentions. Local press, trade bodies, supplier partner pages and real reviews describe your business independently. Google's AI guide is clear that manufactured mentions are not effective, so this has to be real.

Knowledge panels: what you can and cannot control

A knowledge panel is the information box Google shows for some entities. Two things are often confused:

Google's help documentation notes that not all knowledge panels can be claimed yet, and points local businesses to Business Profile instead. For most small businesses, the Business Profile is the entity record that matters.

A worked example

Say a sole-trader electrician trades as "Bright Spark Electrical" but registered the domain brightsparkkent.co.uk, lists "BSE Electrical Services" on one directory, and has an old mobile number on Facebook.

The fix, in order:

1. Choose "Bright Spark Electrical" as the canonical name and one phone number.
2. Update the Business Profile, Facebook, directories and the site footer to match exactly.
3. Add LocalBusiness markup on the home page with sameAs links to Facebook, the Business Profile and the trade body listing.
4. Add an About page naming the electrician, their registration with a competent-person scheme, and the towns covered.
5. Ask the trade body and main supplier to use the same name and link to the site.

None of this is clever. It removes doubt, which is the whole job.

How to see what Google thinks your entity is

You cannot view Google's Knowledge Graph record for your business directly, but you can check the signals around it.

1. Search your exact business name. Does a Business Profile or knowledge panel appear? Is it the right business, with the right details?
2. Search your name plus your town, and your name plus your main service. Do your own site and profiles dominate, or do directories with old details appear first?
3. Search your phone number. Every listing that shows it should show the same name and address.
4. Check Companies House if you are a limited company. The registered name and address are part of your public record, and other sources copy them.
5. **Run your home page through the Schema Markup Validator** to confirm your Organization or LocalBusiness markup is read without errors and matches what the page says.
6. Ask an AI search tool to describe your business with web search on, and note where any wrong details came from. The cited sources usually point straight at the listing that needs fixing.

Developers can also query Google's public Knowledge Graph Search API to see whether an entity is returned for a name, though small businesses often are not in it, and absence there is not a problem in itself.

What is known and what is inferred

What entity SEO will not do

It will not create a knowledge panel on demand, will not make up for a weak website, and will not guarantee mentions in AI answers. It makes your business easier to identify correctly, which helps every other piece of SEO and AEO work land. The same technical access checks covered in how to get cited by ChatGPT and Perplexity and the eligibility rules in how to appear in Google AI Overviews still apply.

Next step

Search your business name in Google and list every profile and directory on the first two pages. Check each for name, address and phone consistency. If you would like the entity audit and structured data handled, it is part of the SEO service.
