Full definition
Cluster models typically pair a broad pillar page with supporting articles that cover sub-intents in depth. Internal links connect supports to the pillar and to each other where relevant, avoiding orphaned posts.
Clusters help distribute relevance, reduce cannibalization when planned carefully, and give readers a logical learning path. Poor clusters are just tag pages with keyword variations and weak unique value.
For AI retrieval, a well-linked cluster offers multiple extractable entry points on the same topic with consistent entity language. See Pillar Page, Internal Linking, and Topical Authority.
Example
A GEO pillar links out to cluster posts on citations, llms.txt, AI crawlers, and entity SEO; each support links back with descriptive anchors.
