What are Topical Clusters?

Topical clusters are a content strategy where you create a pillar page (broad topic) supported by 8-15 cluster pages (subtopics), all interlinked.

Structure:

  • Pillar Page: Comprehensive guide (2000-4000 words) — e.g., "SEO Content Strategy"
  • Cluster Pages: Specific subtopics (800-1200 words) — e.g., "Keyword Research for SEO", "On-Page Optimization"
  • Internal Links: All cluster pages link to pillar + pillar links back

Why It Works:

  • Signals topical authority to Google
  • Improves crawl efficiency
  • Boosts dwell time (users click related articles)
  • Consolidates ranking power around pillar
  • Accelerates content velocity by providing a clear roadmap for content creation
