Hub-and-Spoke Content Architecture

Pillar (hub) covers topic comprehensively. Clusters (spokes) deep-dive each subtopic. Pillar links to clusters; clusters link to pillar and each other.

Hub-and-spoke example

Hub: 'The Complete Guide to Card Grading' Clusters:

• 'PSA vs BGS vs CGC vs SGC'
• 'How long does PSA take?'
• 'What is centering grading?'
• 'How to pre-grade your cards'
• 'When to use Walk-Through service'
• 'Cross-grading explained'
• 'Pop reports and pricing'
• 'Submission packaging guide'
• 'PSA service tiers explained'
• 'Crack-and-resubmit decision'

Result: authority on 'card grading' topic concentrated and distributed.

Implementation

1. Pillar page: 3,000-5,000 words covering everything
2. Cluster pages: 1,500-2,500 words each on subtopic
3. Pillar TOC links to each cluster
4. Each cluster prominently links back to pillar
5. Clusters link to adjacent clusters
6. Build out gradually (1 cluster/week)

SEO benefits

1. Pillar ranks for head term (high volume, hard)
2. Clusters rank for long-tail (easier)
3. Combined: dominate topic in SERP
4. Internal linking compounds authority
5. Total traffic > sum of parts
