What Is Co-Citation?
Co-citation is when two entities, like a brand and a competitor, are mentioned together on the same page without an actual hyperlink connecting them, which search engines can still use as a relevance signal.
Example
An article comparing “the best project management tools” that mentions your brand name alongside three competitors, without linking to any of them, still creates a co-citation association between your brand and that topic.
Why it matters
Co-citation suggests search engines may understand topical relevance and brand association even without a direct link, which is part of why building brand mentions, not just backlinks, is increasingly discussed as valuable for SEO and AI visibility.
