In-Depth Definition
A content cluster is an SEO content architecture strategy where a comprehensive pillar page covers a broad topic while multiple supporting cluster pages cover specific subtopics in depth. All cluster pages link back to the pillar page and to each other, creating a web of topically related content.
Content clusters build topical authority by demonstrating comprehensive knowledge of a subject area. Search engines recognize this interlinked structure as a signal of expertise, and AI models similarly favor sources that provide thorough, multi-faceted coverage of topics.
Implementing content clusters involves identifying core topics aligned with your business, creating comprehensive pillar pages, mapping subtopics to cluster content, establishing strategic internal linking between all pieces, and continuously expanding clusters with new supporting content.
