What Is a Topic Cluster?

A topic cluster is a pillar page plus a set of supporting pages that each cover one specific question, all interlinked by subject.

In plain English

One page owns the subject. Several pages own one question each. Every supporting page links to the pillar, and the pillar links to all of them.

The structure does two things at once: it makes the site easier for a reader to navigate, and it makes the relationship between the pages explicit to a search engine.

What to know

One pillar
The broad page at the centre, targeting the head term.
Specific spokes
One page per question, each with a distinct meaning and URL.
Deliberate links
Up to the pillar, down to the spokes, and sideways where genuinely relevant.
No overlap
Two spokes answering the same question is cannibalisation, not depth.

Why it matters

Clusters are the practical mechanism behind topical authority. They also make content planning tractable, because the question stops being what to write next and becomes which part of the cluster is missing.

Common mistakes

×Publishing spokes with no pillar to anchor them.
×Overlapping spokes that compete for the same query.
×Linking only from the pillar outwards and never back.
×Treating the cluster as finished rather than as something you extend.

FAQs

How many pages make a cluster?

However many questions the subject genuinely contains. Five real ones beat twenty invented ones.

Do clusters need to be in the same folder?

It helps clarity but is not required. The linking matters more than the URL structure.
