Entity SEO builds your brand as a verified, recognisable entity AI search engines can cross-reference. It requires Organisation schema, Wikidata entries, Crunchbase profiles, LinkedIn company pages, and consistent brand descriptions with sameAs links. Entity-optimised businesses see a 24% increase in AI mentions.
Why entities matter for AI
Traditional SEO focuses on keywords. Entity SEO focuses on what your brand is. AI search engines do not just match keywords to queries. They build knowledge graphs of entities (businesses, people, concepts) and verify claims by cross-referencing sources.
When someone asks ChatGPT "Who are the best accountants in Manchester?", AI does not search for pages with those keywords. It looks for accounting entities it can verify. These are businesses that appear consistently across trusted sources with matching descriptions and credentials.
The components of entity SEO
| Component | Purpose | Priority |
|---|---|---|
| Organisation schema | Declares your entity to search engines in structured format | Essential |
| Wikidata entry | Feeds Knowledge Graph across Google, Bing, and AI engines | High |
| Crunchbase profile | Business verification source for AI models | High |
| LinkedIn company page | Professional entity verification + employee signals | High |
| sameAs links | Connects all profiles into one verified entity | Essential |
| Consistent descriptions | Same brand positioning across every platform | Essential |
How AI engines cross-reference entities
AI models check whether the same information appears across independent sources. If your website says "digital marketing agency in London", LinkedIn says "marketing consultancy in the UK", and Crunchbase says "tech company", AI cannot categorise you. Conflicting signals reduce trust.
Consistency is the key. Use the same description, founding date, service categories, and location across every platform. This is why building AI brand trust starts with entity alignment.
The 24% visibility boost
Businesses that complete entity optimisation see a 24% increase in AI mentions compared to those with fragmented signals. This is one of the highest-ROI activities in AI search optimisation. It is a one-time setup that compounds over time.
The work is manual but not technically complex. Create profiles. Align descriptions. Add schema markup with sameAs properties pointing to every verified profile. Once done, AI engines can confidently recommend your business.
