Co-Occurrence

Co-occurrence in SEO refers to the frequency with which keywords or phrases appear near mentions of a brand or URL across the web. The theory holds that search engines can infer topical associations between a brand and particular keywords based on how often those terms appear in proximity to brand mentions — even in content that does not link to the site.

For example, if hundreds of web pages mention your brand name in the same paragraph as specific industry terms, search engines may develop a stronger association between your brand and those topics. Co-occurrence is closely related to the concept of semantic search, where engines use context and association patterns rather than relying solely on exact keyword matches or direct links.
