Topic Cluster

Definition

A topic cluster is a set of related articles and resources organised around a central theme and interlinked so they reinforce one another. Clusters are the structural basis of topical authority.

Why it matters

Well-built clusters help users navigate a subject deeply and signal comprehensive coverage to search systems.

Examples

• A strategy cluster linking openers, hard mode, and information gain.
• A vocabulary cluster linking morphology and spaced repetition.

Best practices

• Define a clear central theme per cluster.
• Interlink members and avoid orphan pages.
