What is Pillar Page?

Pillar pages are the foundation of a topic cluster SEO strategy. They serve as the central hub that covers a broad topic comprehensively while linking to specific 'spoke' articles that dive deep into subtopics. For example, a pillar page titled 'The Complete Guide to Reddit Marketing' would link to cluster articles like 'How to Avoid Shadowbans', 'Best Subreddits for SaaS', and 'Writing Comments That Convert'. Google's algorithms recognise this interconnected content structure as an authority signal. Effective pillar pages are typically 3,000-4,000 words, include a table of contents, cover the topic at a high level, and use contextual internal links to drive readers to cluster content. Every cluster article must link back to the pillar page using the primary keyword as anchor text to consolidate topical authority.
