Topical authority clusters
A topical authority cluster is a pillar page plus interlinked supporting articles covering every facet of a topic, signalling to engines and AI that you're a definitive source.
How to build one
Choose a core topic, create a comprehensive pillar page targeting the broad term, then write focused articles for each subtopic and question. Interlink them all, supporting pages link up to the pillar, the pillar links down to them.
Why it works
Depth and internal linking demonstrate genuine expertise, capture many long-tail queries, and pass authority to your pillar. Clusters are how you become the go-to (and cited) source, for Google and AI alike.
Frequently asked
It's structured and comprehensive, deliberately covering a whole topic and interlinking it, rather than posting scattered, unconnected articles.
Enough to cover the topic thoroughly, often a pillar plus 5–15 supporting pieces. Completeness matters more than a set number.
