A content hub is a pillar page covering a broad topic, surrounded by cluster pages going deep on subtopics. All interlinked. This structure signals topical authority to Google.
How to Build a Content Hub
- Pick one pillar topic: "SEO for Small Business"
- Create the pillar page: comprehensive guide covering all aspects
- Create 10-20 cluster pages: one for each subtopic
- Link every cluster page to the pillar page and to each other
Why It Works
When Google sees a dense web of interlinked content on one topic, it interprets your site as an authority on that topic. The pillar page ranks for the broad keyword, and cluster pages rank for long-tail variations.
