Entity SEO is the practice of optimizing content and site signals around defined entities — your brand, your key people, your services, your locations — rather than around isolated keyword strings alone. An entity is something a search engine can uniquely identify and connect to other known facts about it, typically through structured data, consistent naming, and authoritative external references.
Keywords represent the words people type; entities represent the actual things those words refer to. Strong entity SEO helps a search engine confidently connect "RankPre" with "SEO agency," your founder's name with your company, and your services with the correct category — reducing ambiguity that weaker sites leave unresolved.
