Topic Cluster
What is a topic cluster?
A content structure of a pillar page and linked detail articles that builds topical authority.
A topic cluster is a content structure where a comprehensive pillar page on a main topic is surrounded by many specialized cluster articles and internally linked to them. This hub-and-spoke network signals topical depth and authority to search engines — and also helps AI systems recognize you as a source on a topic.
Structure of a cluster
Pillar page
A broad overview of the main topic, linking to all detail pages.
Cluster articles
In-depth answers to individual sub-questions, linking back to the pillar.
Internal links
The network of links is what makes the topical authority visible.
Why internal linking is decisive
Without clean internal links, a cluster stays a loose collection of articles. Klano suggests matching links automatically and applies them on publish — building real topical authority instead of standalone articles.
Frequently asked questions
How many articles does a cluster need?
There's no fixed number — what matters is covering the most important sub-questions of a topic and linking them cleanly.
Does a topic cluster help with AI search too?
Yes. Clear topical depth and internal linking also help AI systems classify your site as a source on a topic.
