The cluster architecture
One pillar pageper core topic (1500-3000 words, comprehensive). 10-30 cluster articles per pillar, each tackling specific sub-topic (800-1500 words). All cluster pages link back to pillar. Pillar links out to each cluster.
Keyword mapping
Pillar targets primary topic. Clusters target specific questions, comparisons, how-tos.
Entity-based content
Google algorithm shifted from keyword-matching to entity understanding. Cover full conceptual surface area, include related entities, sub-topics, questions naturally. Do not keyword-stuff; entity-stuff.
Internal linking patterns
Every cluster links to pillar with branded + descriptive anchor text. Pillar links to all clusters. Related clusters link to each other.
