What are SEO entities and why do they matter?
In semantic SEO, an entity is any named concept Google can identify and understand — a person, organisation, place, product, process, or idea. Google’s Knowledge Graph maps how entities relate to each other and uses that graph to evaluate whether a piece of content genuinely covers a topic.
When you build a topic cluster around a subject, covering the right entities signals to Google that your site has real depth — not just keyword density. This is the mechanism behind topical authority: Google trusts sites that treat entities as first-class content objects.
Every topical map in this library identifies the key entities for that topic. The pages in this entity library give you a complete reference — definitions, key facts, content opportunities, and related topical maps.
