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.
Search intent, explained
| Intent | The searcher wants to… | Example | Best page type |
|---|---|---|---|
| Informational | learn something | how to fix a leaky faucet | Guide or blog post |
| Commercial | compare options before buying | best faucet brands | Comparison or review |
| Transactional | buy or sign up now | buy kitchen faucet | Product or pricing page |
| Navigational | reach a specific site | moen customer service | That brand's own page |
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.
