Entity SEO is the practice of making the people, businesses, products, and topics on a website unambiguous to search engines and AI systems. An entity is a distinct thing with a stable identity, such as a company, a person, a product, or a location.
The goal is not to repeat a name everywhere. It is to give machines consistent, corroborated facts: what the business does, who it serves, who is accountable for the advice, and how its products or services relate to a category.
What helps establish an entity?
Clear about pages, named authors, consistent company details, relevant structured data, and factual descriptions that agree across a site all help reduce ambiguity. The visible page remains the source of truth. Schema markup can reinforce those visible facts in machine-readable form.
Why does entity SEO matter for AI search?
AI systems need to connect a claim to a real source. When a business, person, and subject area are clear, it is easier for a system to describe and cite the source accurately.
