Content Cluster
Definition
A group of interlinked pages covering a topic thoroughly – one pillar page plus multiple supporting pages that explore subtopics in depth.
What is a Content Cluster?
A content cluster is an organised group of content centred around a core topic. It consists of one pillar page covering the broad topic and multiple cluster pages that dive deeper into specific subtopics – all connected through strategic internal linking.
Think of it as a wheel: the pillar page is the hub, and each cluster page is a spoke. Every spoke connects back to the hub, and the hub links out to all spokes.
Why Content Clusters Work
Search engines have evolved beyond matching keywords to understanding topics. Content clusters demonstrate comprehensive topical expertise, which signals authority to Google.
When multiple pages on your site cover related aspects of a topic and link to each other, you're essentially telling Google: "We know this subject inside out."
Content Cluster Example
Core topic: Email Marketing (pillar page)
Cluster pages:
- Email subject line best practices
- Building an email list
- Email automation workflows
- Email marketing metrics to track
- Choosing an email marketing platform
- Writing effective email copy
Each cluster page links back to the pillar, and the pillar links to each cluster page.

Efficient Content Planning
The cluster model gives you a clear roadmap for content creation.

Links flow naturally rather than being forced.
