GLOSSARY TERM
What is Pillar Page?
Definition
The central comprehensive page in a topic cluster — typically 2,000-5,000 words covering the breadth of a topic, with internal links to detailed cluster pages.
Why it Matters for AI Search
Pillar pages target high-volume head terms; cluster pages target long-tail variants. The pillar accumulates link equity from cluster pages and external links, often outranking purpose-built money pages over time.
