TL;DR — A content cluster is a deliberate content architecture: one pillar page covering a topic broadly, surrounded by supporting pages that each cover a subtopic in depth, all interlinked so engines can see the coverage as one connected body of expertise. The pillar targets the head term; cluster pages target the specific questions, comparisons, and use cases underneath it; internal links flow authority both ways. Clusters are how topical authority gets built on purpose instead of accreted by accident.
Definition & scope
The cluster model also matches how AI engines decompose questions: a prompt like "best batteries for off-grid cabins" fans out into sub-questions about capacity, chemistry, and installation — precisely the pages a well-built cluster already has, each individually citable.
Execution discipline matters more than volume: each cluster page must stand alone as the best answer to its subtopic. Thin pages published to "complete the cluster" dilute rather than reinforce it.
