Content Cluster and Pillar Page
Content cluster — a group of related materials around one large topic: a central page (called a pillar) and a set of detailed articles that address specific questions. All of them link to each other and to the center.
Why do this
- Search understands the topic. Ten related materials are more convincing than one overview text.
- Weight is distributed within the topic. External links to any article strengthen the entire cluster through interlinking.
- Closes the long tail. Each article answers its narrow question.
- Less cannibalization: the roles of pages are predetermined, not formed randomly.
How the cluster is structured
| Element | Task | Under what query |
|---|---|---|
| Pillar page | Overview of the entire topic, navigation through the cluster | Broad, often commercial |
| Cluster articles | Detailed answer to one question | Narrow, more often informational |
| Interlinking | Links everything into a whole | — |
How to assemble
- Take a topic you have something to say about and gather queries — see keyword selection.
- Group them by intent: what can be covered by one page, cover it with one.
- Define the pillar page — it usually already exists, it’s a service or section.
- Write articles by groups, each with a link to the pillar page and to two or three neighboring ones.
- Place links from the pillar page to all cluster articles.
Common mistake
Creating a cluster for the sake of structure, without checking demand: ten articles on a topic that no one searches for will remain ten unvisited pages. Check demand before writing, not after.
How many articles are needed in a cluster
Exactly as many as there are independent questions on the topic. Three substantive articles work better than ten written just for the count: empty materials pull down the rating of the entire section and dilute internal links.
A sign that the cluster is assembled correctly is that each material can be linked from another without strain, and a reader who lands on any article understands where to go next.
