Pillar page
A pillar page is a page that covers a broad topic and links out to more detailed pages on each subtopic, which link back to it.
The pillar targets the main search for the topic. The detailed pages, often called cluster pages, target the narrower searches around it.
HubSpot popularised the pillar and cluster model and documented how it restructured its own blog around it. The idea has since spread to almost every content strategy, and the terms around it overlap. The table separates them.
| Term | What it is | Example |
|---|---|---|
| Pillar page | A single page: the hub of one topic | A managed detection and response service page |
| Content silo | A site structure that groups related pages and links within each group | All security services and their supporting pages in one section |
| Topical map | The plan: every subtopic, its page and its links | A spreadsheet of MDR questions mapped to pages |
| Topical authority | The result: being seen as a strong source on the topic | Ranking across many MDR searches, not one |
The pillar should be a page you want to rank
Most pillar page advice ends with a 5,000-word guide that tries to cover everything. For a B2B company, the pillar is usually better as the service or product page itself, with cluster pages answering the questions buyers ask before they enquire. The links from cluster pages then point at the page that converts, not at a guide that sends readers somewhere else.
That rule has an exception. Where the main search is purely informational, such as “what is zero trust”, a guide is the right pillar, and the service page becomes one of its cluster pages. Everywhere buyers search with commercial intent, make the commercial page the hub.
For a Canadian managed service provider, restructuring the site into content silos with service pages as the hubs is what moved its target keywords up. The cluster pages gave each service page the supporting depth and internal links it lacked.
Common mistakes
-
Writing a pillar page and never linking the cluster pages back to it.
-
Making the pillar so broad it ranks for nothing.
-
Cluster pages that target the same search as the pillar and compete with it.
-
Choosing a guide as the pillar for a commercial topic.
