Entity
In the SEO context, an entity can be anything that is clearly defined, unique, and distinguishable. This term can refer to people, places, things, ideas, categories, events, and more.
Google uses entities to better understand the content of a page and its context. For example, if the page is about “apple,” Google will use entities to understand whether it is about the fruit, the technology company, or something else.
In today’s context, entities are at the heart of the semantic web and the key by which search algorithms are able to identify topics and relate them to each other.Entities for Google are precisely the nodes that allow it to understand the connections between various terms, the needs expressed by users, and the context in which these entities exist and intertwine.
