What is Pillar Page?
A pillar page is a broad, authoritative page on a core topic that touches every sub-aspect and links out to its own deeper cluster posts. Those link back to the pillar. The result is a densely interlinked topic cluster rather than isolated single articles.
Search engines read this structure as a signal of topical depth: covering a topic across a pillar plus ten cluster posts reads as more credible than a single article. The internal linking also channels authority to the pages that matter.
The model doubles as an editorial plan: the pillar defines the territory, the cluster posts the individual long-tail keywords. This very glossary is a cluster - each definition a cluster page pointing to related terms.
Why does Pillar Page matter?
Isolated, unconnected articles rarely rank for long. A clean topic cluster builds compounding topical authority - and is the structure AI systems prefer for understanding a subject area.
