External backlinks pass PageRank to your landing pages, but internal linking architecture determines how efficiently that ranking power is distributed across your entire domain index.

1. Topic Cluster Silo Architecture

• Pillar Page (The Core Hub): Broad, comprehensive 3,000+ word overview of a high-value category (e.g., "Enterprise Link Building Guide").
• Cluster Articles (The Spokes): 10–15 sub-topic guides (e.g., "Anchor Text Distribution", "Digital PR", "Broken Link Building") linking upward to the pillar.
• Bidirectional Cross-Linking: Related spoke articles link horizontally to one another with rich contextual anchor text.
