Keyword Clustering: How to Group Queries Without Creating Cannibalization
Keyword clustering groups searches that can be satisfied by the same destination, reducing duplicate pages and giving each URL a clearer job.

Why clustering matters
Without clustering, a keyword export can turn into dozens of nearly identical articles. Those pages compete for internal links, dilute maintenance effort and confuse the purpose of each URL.
Start with intent
Group phrases when the person wants substantially the same outcome. Wording can differ while intent remains identical.
Use SERP overlap
SERP overlap is strong evidence. If two queries return many of the same ranking pages, one well-designed destination may be able to serve both.
Choose a primary topic
Choose a primary topic that best describes the page, then include natural subquestions and variants where they improve the answer. Do not stuff every phrase into headings.
Know when to split
Split when the user needs a meaningfully different outcome, page type or level of detail, or when the SERPs diverge enough that one page would become incoherent.
