What an "entity" is in the context of search
In search and AI, an entity is a distinct, real-world thing that can be uniquely identified, a person, a place, an organisation, a product. Google's Knowledge Graph contains hundreds of billions of entities and the relationships between them. When Google has your business as an entity in its Knowledge Graph, it knows who you are, what you do, and where you operate, independently of any specific page you've published.
For AI tools, entity recognition is even more critical. When ChatGPT, Perplexity, or Google AI Overviews generate an answer, they're drawing on their understanding of entities. A business that exists as a clear entity in that understanding gets cited. A business that's just a website doesn't.
The three pillars of entity SEO
Entity disambiguation
Making sure AI systems and Google can uniquely identify your business, distinguishing "Smith Plumbing Leeds" from every other plumbing company named Smith. Consistent name, location, and category across all sources.
Entity association
Building the connections between your entity and relevant topics, locations, and categories. Publishing content that puts your entity name in the same context as the subjects you want to be associated with.
Entity authority
Earning mentions from sources that Google and AI tools already recognise as credible. Each mention from a trusted source reinforces your entity's credibility and topic associations.
How to build entity signals: step by step
-
Define your entity clearly on your website
Your homepage and About page should state unambiguously: what type of business you are (using schema markup to confirm this), where you're based, and what you specialise in. Use your exact business name consistently, not abbreviations, trading names, or variations.
-
Add Organisation or LocalBusiness schema
Schema markup is the most direct way to declare your entity to AI systems. At minimum: @type, name, url, address, telephone, description, and sameAs properties. The sameAs property links to your profiles on Google, LinkedIn, and relevant directories, confirming they're all the same entity.
-
Claim and fully complete your Google Business Profile
Google Business Profile is the primary anchor for your local entity in Google's systems. Complete every section: name (exactly matching your website and legal name), primary and secondary categories, services, description, opening hours, and photos. Add posts regularly to signal an active entity.
-
Ensure NAP consistency across all sources
Name, Address, Phone number, identical across your website, Google Business Profile, Bing Places, Apple Maps, Yell, Companies House, and any other directories. Even minor variations (Ltd vs Limited, St vs Street) can create disambiguation confusion for AI systems.
-
Build external entity mentions
Get your business named on authoritative external sites, not just linked to, but named. Trade directories, industry publications, partner pages, and review platforms all contribute. Each mention from a trusted source reinforces your entity's existence and topic associations in AI training data and retrieval indexes.
-
Create topically associated content
Publish content that consistently puts your entity name in the context of your specialism. A cluster of content about AI search visibility for UK small businesses, all authored by or attributed to your business, builds the association that gets you cited when a related query is asked.
Why entity SEO is the foundation of AI visibility
Every aspect of AI visibility, citations, mentions, AI Overview inclusion, AI Mode sourcing, depends on entity recognition. An AI tool that doesn't recognise your business as a known entity can't cite it, recommend it, or accurately describe it. Entity SEO isn't a separate discipline from AI visibility work; it's the foundation that makes everything else possible.
The good news for UK small businesses: entity signals are buildable from scratch, and many of the highest-impact actions (GBP completion, NAP consistency, schema markup) require effort rather than budget.
