What is entity SEO? How search and AI understand brands
Entity SEO in plain English: what entities are, how search engines and AI connect them to facts, and how to make your brand a clear, consistent entity.
From keywords to things
Early search engines matched words. Modern search systems also try to understand entities — the real-world things that words refer to. “Apple” in a query about iPhones and “apple” in a query about pie recipes are different entities. Google introduced its Knowledge Graph in 2012 with the phrase “things, not strings” to describe this shift.
Large language models build similar associations. When an AI answer describes a company, it is drawing on what it has retrieved and learned about that entity: what category it belongs to, what it offers, where it operates, who leads it, how others describe it.
What counts as an entity
- Organisations — your company, competitors, partners
- People — founders, authors, experts
- Products and services — what you sell
- Places — offices, service areas
- Concepts — the topics you’re associated with (e.g. “payroll compliance”)
Entity SEO is mostly about the first three, and about the relationships between them and concepts: “Prisol” → is a search visibility company → based in Hyderabad → offers SEO, AEO, GEO → founded by Prithvi Somavarapu.
Why it matters
- Correct categorisation. If search and AI systems can’t tell what kind of company you are, they can’t recommend you for the right questions.
- Accurate descriptions. Clear, consistent facts reduce the chance of outdated or wrong statements in AI answers.
- Disambiguation. Clear entity signals help separate you from similarly named companies.
- Trust signals. Facts corroborated by independent sources are more credible than claims made only on your own site.
The four parts of entity SEO
1. A precise description
One sentence that says what you are, who you serve and what makes you different — in plain category language buyers use.
2. Consistency everywhere you control
The same name, description, address, contact details, leadership and offerings on your website, Google Business Profile, LinkedIn, directories and marketplaces. (For local businesses this is often called NAP consistency.)
3. Accurate structured data
Organization markup with legal name, logo, contact points and sameAs links to your official profiles; Person markup for real authors; Product or Service markup where relevant — always matching visible content.
4. Corroboration by others
Independent sources — press, associations, partners, review platforms — describing you the same way. This is where brand mention building and digital PR support entity work.
How to check your entity today
- Search your brand name in Google and Bing. Is there a knowledge panel? Is it accurate? Are other companies mixed in?
- Ask ChatGPT, Gemini and Perplexity “What is [brand]?” and “What does [brand] do?”. Note the category and facts used.
- Compare your descriptions across your top ten profiles. How many different versions exist?
