What is a pillar page?

A pillar page is a broad page that covers a whole topic at a high level and links to detailed cluster pages for each subtopic. It targets the main, broad search for the topic and acts as the hub of a content cluster. Category and hub pages often play this role.

What it contains

  • A clear overview of the topic and why it matters.
  • A short section on each subtopic, linking to its full page.
  • Original data or a summary table where possible.
  • Navigation to related pillars.

Pillar vs cluster page

Pillar Cluster page
Scope Whole topic One subtopic
Depth Overview In depth
Target search Broad Specific
Links To every cluster page To pillar and siblings

Example

Our directory category pages, such as the AI tool directories list, work as pillars: they summarise the category with numbers and link to each directory's full profile, which links back.

Common mistakes

  • Making the pillar a thin list of links with no substance of its own.
  • Repeating the full content of cluster pages, which causes cannibalisation.
  • Forgetting to link new cluster pages from the pillar.

FAQ

How long should a pillar page be?

Long enough to cover every subtopic briefly; detail goes on cluster pages.

Can a pillar page be a list?

Yes. Category hubs and ranked lists often work well as pillars.

Should pillars be in the main navigation?

Usually yes; they're your most important topic pages.

Can a glossary hub be a pillar?

Yes. A glossary hub that links every term in a category acts as a pillar for that topic.
