Pillar Page
Quick Definition
A pillar page is a comprehensive, long-form page that covers a broad topic in depth and links out to related cluster content pages. It serves as the central hub of a topic cluster strategy.
Why It Matters
Pillar pages are the backbone of a topic cluster strategy. They help you build topical authority by creating one comprehensive resource that links to detailed subtopic pages. Sites that use pillar-cluster architecture consistently outrank sites with disconnected, random blog posts.
Real-World Example
HubSpot's 'Ultimate Guide to SEO' is a classic pillar page. It covers SEO broadly in one long page, then links to separate cluster pages about keyword research, on-page SEO, technical SEO, and link building. Each cluster page links back to the pillar, creating a web of topical authority.
Signal Connection
Relevance -- A pillar page establishes your site as a comprehensive resource on a topic. By covering the broad topic and linking to detailed subtopics, you create a relevance network that signals deep expertise to search engines.
Pro Tip
Start with one pillar page for your most important topic. Make it 3,000-5,000 words covering the topic broadly, then create 5-10 cluster pages going deep on each subtopic. Link every cluster page back to the pillar and from the pillar to each cluster.
Common Mistake
Creating a pillar page that goes too deep into subtopics instead of linking to cluster pages. The pillar should provide an overview with enough detail to be useful, then direct readers to cluster pages for depth. If your pillar page tries to cover everything, there is no reason for cluster pages to exist.

Show Answer
Answer: B. The pillar page covers a broad topic and links to cluster pages that go deep on subtopics
A pillar page provides a comprehensive overview of a broad topic, while cluster pages dive deep into specific subtopics. They interlink to create a topical authority structure that helps search engines understand your expertise.
