Topic cluster
Also known as: content cluster, pillar page
What is topic cluster?
A topic cluster is a pillar page covering a broad subject plus a set of child pages covering its sub-questions, all linked to each other. It is the standard architecture for building topical authority.
Clusters make crawl paths obvious, distribute link equity to deep pages, and give AI models a coherent entity to associate with a subject.
