How a topic cluster works
A central page introduces the subject and helps readers choose a path. Supporting pages explain distinct questions or decisions in more depth. Useful internal links connect the overview and the focused pages without forcing every reader through the same sequence.
The structure should reflect a real subject relationship. A shared keyword is not enough if the pages answer unrelated needs, and every variation of a phrase does not justify another supporting page.
Planning a B2B cluster
Map the questions a buyer asks about a problem: what it means, when it matters, how options differ, what implementation requires, and how success is measured. Identify which questions belong together and where a separate page would be genuinely useful.
Connect educational material with relevant evidence and service information. Avoid turning every supporting article into the same sales page; readers need different levels of detail at different stages.
A B2B example
An agency’s AI search overview links to definitions of AEO, GEO, AI visibility, and AI citations. A deeper guide explains practical evaluation, while a service page describes the work available. The pages form a coherent path from terminology to a business decision.
How to evaluate a cluster
Check that each page has a distinct purpose, that important questions are answered, and that links make the relationships clear. Review query coverage, reader movement, and qualified enquiries by topic rather than counting pages as the outcome.
Maintain the cluster when information changes. An outdated overview or broken link can undermine an otherwise useful set of supporting pages.
Frequently asked questions
Does a topic cluster need a fixed number of pages?
No. Its size depends on the subject and the buyer’s needs. Create enough useful coverage to answer the relevant questions.
Is a glossary a topic cluster?
It can support one. Related definitions and deeper resources become more useful when their links explain how the terms fit together.
