Pillar Page
In one line
A pillar page is the hub at the centre of a topic cluster — a broad page that maps the whole theme and routes readers out to the narrower cluster pages.
Going deeper
A pillar page covers the full breadth of theme A on a single hub: definitions, scope, key questions, what to read next. It routes out to its cluster pages like an index, and those clusters route back in — concentrating topical authority into one structure.
The classic failure mode is the thin-but-long pillar — five thousand words that never answer any specific sub-question well. You end up with a page no human, search engine or LLM has any reason to quote. Real pillars are broad on purpose but tight on definitions, scope and entry-level guidance.
If anything, pillars matter more in AI search than they used to. LLMs answering category-level questions lean toward a single well-organised page that maps the whole topic, so one strong pillar can quietly drive citations across many related prompts.
