Pillar page
A broad, comprehensive page that introduces a whole topic and links out to detailed supporting pages within the same cluster.
In full
A pillar page targets the head term and serves as the internal linking hub for its cluster, concentrating and redistributing link equity. To rank it must be genuinely useful on its own, not a table of contents; the strongest ones answer the top-level question fully and then hand off. Pillar pages are also natural link targets for digital PR because they are citable overviews.
Example
'Technical SEO: a complete guide' covers the whole field at overview depth and links to 25 detailed subtopic pages.
