What is a Content Cluster?

A content cluster is a group of related articles linked to a main pillar page. It improves topical authority and site structure.

Understanding Content Clusters in SEO

A content cluster is a strategic approach to website content where a main pillar page acts as the central hub, linking to multiple related subtopic pages, and vice versa. This structure helps search engines understand your site’s content hierarchy and establishes your authority on a particular topic.

Content clusters are designed to improve topic relevance, internal linking, and user navigation, which can significantly boost organic rankings. Rather than isolated pages targeting individual keywords, clusters create a cohesive content ecosystem that signals expertise to search engines.
