Keyword clustering is grouping queries that should be served by the same page, usually because they share search intent and return substantially the same results. It decides how many pages a topic needs rather than which keywords to target.
Why Keyword Clustering matters for SEO
Clustering wrong produces either cannibalisation, where several of your pages compete for one intent, or thin coverage, where one page tries to serve intents that need separate treatment. Both are structural problems that content quality cannot fix.
Pro tip on Keyword Clustering
Group by result overlap rather than by wording: if two queries return largely the same pages, one page can serve both. Your own Search Console query export is the best clustering input, because it reflects queries your pages already receive.
