Related entities and co-occurrence

From EntitySEO.wiki, the entity SEO reference · Last reviewed · By · Published by Local Blitz · How we research

Related entities are the things that are consistently connected to a topic, such as the tools, standards, people, places and sub-concepts that a complete explanation mentions. You find them through knowledge graph relationships (Wikidata statements, “People also search for”), through co-occurrence in top-ranking pages, and from your own expertise. Use them to plan coverage and internal links, not as a keyword list.

What is co-occurrence?

Co-occurrence means two entities or terms appearing together across many documents. If most authoritative pages about “knowledge panels” also mention “Knowledge Graph” and “Google Business Profile”, those entities are strongly related to the topic. The idea comes from general information-retrieval practice; Google does not publish how it uses co-occurrence. Practitioner practice

  5. Record everything in your entity map.

How is this different from keyword lists?

Keyword tools list phrasings; related entities list things. A page can use every keyword variation and still miss a concept that a complete answer needs. Google’s helpful content guidance asks whether content provides “a substantial, complete, or comprehensive description of the topic.”[4] Officially documented See topical authority.

Frequently asked questions

Is co-occurrence a Google ranking factor?

Google has not documented it as one. It is a practical way to see what complete coverage of a topic looks like.

How many related entities should a page mention?

As many as a complete, helpful answer needs, and no more. Coverage should follow the reader's needs, not a count.
