What is a topic cluster?
A topic cluster is a group of interlinked pages that cover one subject in depth. A central pillar page covers the broad topic, and supporting pages cover specific subtopics, all linking to and from each other.

How topic clusters work
The pillar page gives an overview, and each supporting page answers a narrower question. Links between them show how the content connects, so both visitors and search engines can follow the path.
Covering a subject thoroughly can help demonstrate expertise on it.
How to plan a topic cluster
Pick a topic that matters to your business and research the questions people ask about it. Assign each question or keyword group to its own page, making sure the pages serve different intents.
Link supporting pages to the pillar and to each other where relevant, using descriptive anchor text.
Common questions
What is the difference between a topic cluster and a pillar page?
The pillar page is the central page. The topic cluster is the whole group, including the pillar and its supporting pages.
How many pages should be in a topic cluster?
There's no required number. Include enough pages to cover the important subtopics, and avoid creating thin pages just to fill the cluster.
Do topic clusters help SEO?
They can, by organizing content, strengthening internal links, and showing depth on a subject. They work best when each page is genuinely useful.
Can a page belong to more than one cluster?
Yes, when the topics overlap. Keep each page focused on a clear purpose so clusters don't compete with each other.
