A long, comprehensive page that covers a broad topic at the center of a content cluster — designed to rank for a high-volume head term and feed link equity to subtopic pages.
A good pillar page is 2,000-5,000 words, scannable with H2/H3 headings, includes a table of contents, and links out to 10-30 deeper articles. The pillar earns backlinks; the subtopic pages catch the long-tail traffic.
Real-world example
VibecodeAEO's 'What is Answer Engine Optimization?' page is a pillar — it covers AEO broadly, links to 12 subtopic articles (on llms.txt, schema, citations, etc.), and earns most of the inbound links in the cluster. AI engines treat it as the authoritative entry point for the topic.
Frequently asked questions
What makes a strong pillar page?+
Length (2,000-5,000 words minimum), a table of contents with anchor links, comprehensive coverage of the topic, links to all subtopic articles in the cluster, original data or research, FAQ schema, and frequent updates. The pillar should be the most complete resource on the topic, not just a hub page.
How is a pillar page different from a regular blog post?+
A blog post covers one narrow angle of a topic and is 500-1,500 words. A pillar page covers the entire topic at a high level and is 2,000-5,000+ words. Blog posts link into the pillar; the pillar links out to the blog posts. Pillar pages target broad, high-volume head terms.
