Why this matters
Clusters help a site cover a topic in depth instead of publishing disconnected articles.
Setup
Choose a pillar topic, list supporting questions, and map each support post back to the pillar with contextual links.
Implementation notes
Use categories for broad navigation and tags for narrower relationships. Avoid creating a new taxonomy label for every small keyword variation.
Final checklist
- Pillar topic is clear
- Supporting posts answer subtopics
- Internal links connect the cluster
