What is Co-occurrence?
Brand or keyword mentions appearing near links or topics without direct anchors. Engines read co-occurrence as topical association, which is why unlinked mentions still move understanding.

Co-citation
Two pages frequently cited together, implying topical relationship. Being co-cited with established authorities borrows relevance no single link states explicitly.
Unlinked Brand Mention
A mention of your brand without a hyperlink. In classic SEO it is a reclamation opportunity; in AI search it is also visibility, since assistants cite and repeat familiar names.
Entity Optimization
Writing so engines resolve which real-world things (people, products, places) a page is about: consistent names, disambiguating context, sameAs links, and schema. Entities are how modern retrieval thinks.
Off-Page SEO
Everything that builds a site’s reputation elsewhere: backlinks, mentions, reviews, and digital PR. Off-page signals validate what on-page content claims about expertise.
Referring Domain
A unique site linking to you. Domain diversity matters more than raw link counts: 100 links from one site look like one relationship, not 100 votes.
Link Equity
The ranking value passed through a link, shaped by the source’s authority, relevance, and number of outbound links. Internal links distribute equity; external links earn it.
