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.
