Group your keywords into topic clusters
Paste your keyword list, one per line. This tool de-duplicates and clusters them by shared words, then suggests a head term for each topic.
Why clustering matters
One strong page per topic, not many thin ones
Keyword clustering groups related search terms that should live on the same page. Build one page per keyword and you get thin, near-duplicate pages competing with each other — cannibalization. Cluster first, and you build one focused page per topic that can actually rank and get cited.
This tool clusters by the words your keywords share, deterministically. It's a fast first pass you can review and adjust before you plan your pages.
What un-clustered keywords cost you
- Near-duplicate pages compete for the same terms
- Authority is split across thin pages
- Assistants can't tell which page is canonical
- You write more pages for less coverage
How the Keyword Clustering Tool works
Paste your keywords and the tool groups related terms into topic clusters with a suggested head term for each.
Cluster by shared words
Keywords that share significant words are grouped into the same topic cluster.
Build one page per cluster
Use the head term as the page target and cover the rest as sections.
The signals that matter
What this tool does
These are the deterministic steps behind your clusters.
Normalize — trim and lowercase
De-duplicate — drop repeats
Tokenize — drop stopwords, singularize
Cluster — group by shared words
Head term — the most central keyword
One page — per topic cluster
group keywords into topic clusters

Clusters tell you what to build, not who cites you
Clustering shows you which pages to build. Run the full AEOMaster audit to see whether AI answers actually find, mention, and cite those pages.

What does the keyword clustering tool do?
It groups a list of keywords into topic clusters by how many words they share, and suggests a head term for each cluster. Each cluster is usually one page to build, so you avoid thin, near-duplicate pages competing with each other.
What is keyword clustering?
Keyword clustering means grouping related search terms that should live on the same page. Instead of one page per keyword (which creates cannibalization), you build one strong page per topic and cover the variants as sections.
How do I enter my keywords?
Paste one keyword per line (commas also work). The tool normalizes and de-duplicates them, then clusters by shared significant words — so “ai visibility checker” and “ai visibility tool” land together.
Does it use AI or search volume data?
It clusters by the words keywords share, not by meaning — no AI, no login, no crawling. That makes it fast, private, and completely deterministic, but it groups by wording rather than intent, so review the clusters before acting.
What is the suggested head term?
The head term is the keyword whose words are most common across the cluster — usually the broad term to build the page around. Treat the rest as sections, FAQs, or supporting content on that page.
Will clustering get my pages cited by AI?
Clustering tells you which pages to build. Whether AI answers actually mention and cite those pages depends on your content, authority, and evidence — which is what the full AEOMaster audit measures.
