Entity Cluster
A group of related pages that collectively establish topical authority around a named entity (a product, concept, person, or place).
An entity cluster is a content architecture pattern: one pillar page that comprehensively defines a topic, surrounded by cluster pages that drill into specific aspects, all internally linked. AI engines use entity clusters to identify which domains are authoritative on a topic.
Why do entity clusters matter for GEO?
AI engines build internal knowledge graphs from web crawl. A domain with 12 well-linked pages on "Generative Engine Optimization" registers as a stronger authority than a domain with 1 high-quality page on the same topic. Citation odds rise proportionally.
How big should an entity cluster be?
Pillar + 6-12 spokes is typical for a competitive topic. Each spoke is a standalone article that links back to the pillar with anchor text containing the entity name.
