# Map Keywords to Topic Clusters

Topic clustering is the modern approach to SEO architecture. Instead of targeting one keyword per page in isolation, you group semantically related keywords into clusters with a pillar page at the center and supporting pages around it. Google rewards this structure with higher rankings because it demonstrates deep expertise on a topic.

ToolRouter's cluster_keywords skill analyzes semantic relationships between keywords and automatically groups them into meaningful clusters. Each cluster becomes a content hub: one comprehensive pillar page targeting the broadest term, with supporting articles targeting specific subtopics that link back to the pillar.

This matters because Google's algorithm increasingly evaluates topical authority — sites that cover a subject comprehensively outrank those with scattered, unrelated content. Clustering also eliminates keyword cannibalization where multiple pages compete for the same terms. It creates natural internal linking structures, makes content planning systematic rather than ad hoc, and helps readers find related content they need.
