A pillar page is a long-form page that covers a broad topic comprehensively and links out to a set of more detailed cluster pages on specific subtopics. It sits at the top of a content silo and acts as the primary entry point for that topic on your site.
A pillar page on “B2B SEO” would cover the topic at a high level: what it is, how it differs from B2C SEO, the main components, and how to approach it. Each section would link to a dedicated cluster page that goes deeper: a separate page on B2B keyword research, another on technical SEO for SaaS, another on link building for B2B. The cluster pages link back to the pillar, reinforcing the topical connection.
Pillar pages rank for broad, high-volume head terms. Cluster pages rank for more specific, lower-volume queries. Together they capture traffic across the full range of intent within a topic. The pillar page format works well for B2B sites because it mirrors how buyers research: they start with broad questions and progressively narrow to specific ones before making a decision.
