Guide

Why cluster keywords?

Many keywords are different ways of asking the same thing. Writing a separate page for each splits your effort and makes your pages compete with each other (keyword cannibalization). Clustering groups them so one strong page targets the whole group.

Clusters here are grouped by meaning and intent. The most precise method is checking whether the same pages rank in Google for each keyword, so spot-check large clusters.

Tips

Tips for using the keyword clustering tool

Clean the list first

Remove duplicates with the remove duplicate lines tool before clustering.

One page per cluster

Target the cluster's main keyword in the title and the others in headings and text.

Split mixed intent

If a cluster mixes "buy" and "how to" keywords, split it; they need different pages.

Verify big clusters

Search two keywords from a cluster. If the same pages rank, they belong together.
