Entity SEO
又称: entity optimization, entity-based SEO, entities in search
一句话解释
Entity SEO is the practice of making search and AI systems recognise your brand as a distinct, well-defined thing rather than a string of characters. It covers consistent naming, unambiguous descriptions, and corroboration across independent sources so a system can confidently identify who you are.
Strings versus things
Early search matched strings. If your page contained the phrase, you were a candidate. Entity-based systems work differently: they resolve the query to a thing in the world, then look for what is known about that thing.
The practical consequence is that being mentioned is not enough. The system has to be confident the mention refers to you. A brand with a generic name, inconsistent descriptions and no corroborating sources is hard to resolve, and hard-to-resolve entities get left out of answers that require confidence.
What makes an entity legible
- One name, used consistently. Every variant you use in the wild is another string a system has to connect back to you.
- One category. If your own materials describe you three different ways, the engine picks one — possibly the wrong one.
- Independent corroboration. Facts repeated across sources you do not control are what turn a claim into a known property.
- A stable anchor. A complete profile on a widely-read platform gives systems something to attach facts to.
Where this bites in practice
Two failure modes recur. The first is the shared name: another company in another industry has better entity signals, so questions about "your" name resolve to them. The second is the description drift — your website, your LinkedIn and your review-site profile each describe a slightly different company, and the engine has no basis for choosing.
Neither is fixed by publishing more content. Both are fixed by making the same facts appear the same way in enough places that the ambiguity disappears.
常见问题
- What is an entity in SEO?
- A distinct thing a system can identify and hold facts about — a company, person, product, place or concept. The key property is that an entity is language-independent: the entity behind 'Apple the company' is the same object however it is written, and separate from the fruit.
- How do you build entity clarity for a brand?
- Use one consistent name, category and description everywhere you appear; make sure independent sources corroborate the same facts; and give systems something unambiguous to anchor to, such as a complete profile on a widely-read platform. Consistency across sources matters more than any single page.
- Does entity SEO matter for AI answers?
- More than for classic search. An answer engine has to decide which brand a question is about before it can recommend one. Ambiguity — a generic name, conflicting descriptions, two companies sharing a name — is resolved by picking the clearer entity, which may not be you.
相关术语
- Brand authority
Brand authority is the credibility a brand has earned in its category, and the signals that communicate that credibility to people and to search systems. It is built through independent corroboration — what others say about you — far more than through anything you publish about yourself.
- Brand visibility
Brand visibility is how often and how prominently a brand appears in the places its buyers are looking. It has traditionally been measured through search rankings, impressions and media coverage; the newer and harder component is whether AI answer engines name the brand when asked what to buy.
- AI visibility
AI visibility is how often AI answer engines name and cite your brand in response to the questions your customers ask. It is measured as two separate rates per engine — how often the prose names you, and how often the citations include your domain — tracked across repeated runs rather than single answers.
- Brand mention
A brand mention is when the prose of an AI answer names your brand. It is tracked separately from a citation, which only means the answer's source list included your domain. A mention puts your name in front of the reader; a citation may not.
