Topic cluster
A group of related pages organized around a central subject and connected through deliberate internal links.
Also called: topic clusters, content cluster, content clusters
Definition
A topic cluster arranges useful pages around related customer questions, services, or concepts. The pages should have distinct purposes and link where the relationship helps a reader, rather than existing only to repeat variations of a keyword.
Why it matters
Coherent clusters make coverage, gaps, duplication, and internal-link paths easier to understand and maintain.
Common misunderstanding
A topic cluster is an information-architecture method, not a guaranteed ranking tactic or a license to mass-produce thin pages.
