Keyword Cluster Maker

A keyword cluster is a group of related search terms organized around one central pillar topic. The pillar page covers the broad topic comprehensively, while sub-pillar pages target specific long-tail variations. All pages interlink, sending topical authority signals to search engines and helping users navigate related content. Learn more in my guide to SEO fundamentals.

A pillar page is a comprehensive, long-form page that covers a broad topic in depth and links out to more specific sub-topic pages. It acts as the hub of a content cluster, consolidating topical authority. Google rewards this structure because it mirrors how users actually explore a subject — starting broad and drilling into specifics.

A strong cluster typically has 4 to 8 sub-pillar pages. Fewer than 4 and the cluster lacks depth. More than 8 and you risk keyword cannibalization or thin content. This tool generates 5 sub-pillars as a starting point — you can expand or trim based on your keyword research and competitive analysis.

Every sub-pillar page links back to the pillar page, and the pillar page links to every sub-pillar. Sub-pillars can also cross-link to each other where relevant. This creates a tight internal link network that tells Google all these pages are topically related, boosting the entire cluster's authority for the seed keyword.
