Content Cluster / Topic Cluster
Quick definition
A content cluster (or topic cluster) is a group of interlinked articles built around a central pillar page covering a broad topic in depth.
The cluster model uses a pillar page (broad overview) and supporting cluster pages (specific subtopics), all interlinked. It signals topical authority to search engines.
Why Content Cluster / Topic Cluster matters
Topic clusters tend to outperform isolated long-form posts because they capture more long-tail traffic, distribute internal authority better, and build coherent topical depth.
How Content Cluster / Topic Cluster works in practice
Map clusters before writing: list one pillar topic, 8–20 subtopic articles, and the internal-linking pattern that will connect them. Then execute over weeks or months.
Best practices
- Plan the full cluster before publishing the first article.
- Link every cluster page back to the pillar (and vice versa).
- Use consistent terminology across the cluster.
- Refresh the pillar annually.
