Co-citation refers to two websites being mentioned together within the same piece of content, without necessarily linking to each other directly, which some SEO theories suggest can create an implied relevance or association signal for search engines.
Unlike a direct backlink, co-citation relies purely on the two entities being referenced near each other in the same context, suggesting a topical or competitive relationship even without an explicit hyperlink connection.
While co-citation’s exact algorithmic impact remains less clearly confirmed than direct link signals, being frequently mentioned alongside established, authoritative brands in relevant content likely still contributes positively to overall entity and topical relevance.
