Keyword Cluster Tool
Quick answer
Paste a keyword list and the tool groups terms by search intent into page-level clusters, naming the target page for each and marking the primary keyword. Clustering by intent rather than by string similarity is what stops you writing five pages that all compete for the same query.
One page per cluster, not one page per keyword. Paste the list and see which terms belong together.

Why clustering beats one page per keyword?
Search engines resolve queries to topics, not strings. "Ai writing tools", "best ai writing tools" and "ai writing tools free" are three phrasings of one job, and three thin pages competing for it will lose to one thorough page that answers all of them.
Intent is the second axis, and it is the one most lists ignore. A comparison query and a pricing query share a head term but need completely different pages — one wants a table of options, the other wants numbers and a signup path. Splitting on intent is what stops a single page from serving nobody well.
Clustering here works on the shared head terms in your list plus the intent words each keyword contains, so the output is only as good as the list you paste. Feed it real keyword-research exports rather than a handful of guesses.
What is the Keyword Cluster Tool?
| What it answers | Group keywords into pages by intent. |
|---|---|
| How the answer is produced | Search engines rank pages against intent, not individual keywords, so publishing one page per keyword splits authority and creates pages that compete with each other. |
| What you need to enter | Paste your keyword list, including long-tail variants from search console. |
| Where it stops being reliable | It has no search volume, difficulty or SERP data; validate clusters with a keyword tool. |
| Cost and sign-up | Free, runs in your browser, no account and no stored inputs. |
How keywords are grouped into clusters?
Search engines rank pages against intent, not individual keywords, so publishing one page per keyword splits authority and creates pages that compete with each other. Clustering groups terms that a single page can satisfy.
The tool groups by shared intent and semantic overlap: informational terms asking the same underlying question go together, while transactional and comparison terms are separated because they need a different page type. Each cluster is assigned a primary term for the title and secondary terms for headings and body coverage.
It also flags cannibalisation risk — where two of your existing pages target the same cluster — since consolidating those is often the fastest ranking improvement available to an established site.
How do you use the Keyword Cluster Tool?
- 1.Paste your keyword list, including long-tail variants from search console.
- 2.Review each cluster and confirm one page really could answer all of it.
- 3.Assign one primary term per cluster and build the page around that intent.
- 4.Merge or redirect existing pages that target the same cluster.
What can this tool not tell you?
- It has no search volume, difficulty or SERP data; validate clusters with a keyword tool.
- Grouping is based on wording and intent heuristics, not on live result comparison.
- Intent shifts over time and clusters need periodic review.
What should you know about clusters exist to stop your own pages competing?
The reason to cluster keywords is not tidiness — it is to prevent the situation where three of your own articles target near-identical intent and split the signals between them. Search engines pick one page per site for a given query, so the extra pages do not add traffic; they dilute link equity and internal relevance, and they consume writing time that could have gone into depth. Clustering answers a single question: how many distinct pages does this topic actually justify?
The grouping rule that matters is intent, not string similarity. 'Best CRM for small business' and 'small business CRM pricing' share words but describe different moments — one is shortlisting, one is validating budget — and they usually deserve separate pages. Meanwhile 'how to write a cover letter' and 'cover letter tips' look different and are the same intent, so they belong on one page with both phrasings used naturally in headings. Getting this backwards is the single most common cause of cannibalised content.
Cluster structure then translates directly into site architecture. One pillar page covers the broad intent and links out to the specific sub-intents; each sub-page links back. That internal linking is not decoration — it is how a crawler learns which page is the authoritative one for the head term, and it is the part most content plans skip in favour of publishing more articles.
Clustering matters because search engines resolve queries to topics, not strings. Ten near-identical pages targeting ten variations of the same phrase compete with each other, split whatever authority the site has, and typically leave all ten outranked by a single thorough page elsewhere. Grouping those variations into one cluster and writing one substantial page for it is not a compromise; it is the arrangement search results have rewarded for years, and it also happens to be less work.
Clusters also age unevenly, and that is easy to miss once a page is published and performing. A comparison cluster tied to specific product names or prices needs revisiting every few months, because the underlying answer changes even though the search query does not. A definitional cluster — 'what is amortisation' — barely moves for years. Treating every published cluster as equally finished is how a site ends up ranking well for a page that quietly recommends a discontinued product or a price that nobody charges anymore.
What do worked examples look like?
Splitting an over-merged topic
Forty terms around 'email marketing' initially collapsed into one page. Regrouped by intent they became four: a definitional pillar, a deliverability troubleshooting page, a template library and a platform comparison. Each targets a different stage, and the pillar links to all three, which is what let the head term rank rather than the thin definitional page competing with itself.
Merging pages that were cannibalising
Three posts targeted 'how to write a resume', 'resume writing tips' and 'resume advice' — identical intent, three thin pages, none ranking. Consolidating into one comprehensive page with redirects from the other two recovered the position within a crawl cycle, with no new content written.
When two keywords look similar and are not
'Best running shoes' and 'how to choose running shoes' contain the same nouns and belong on different pages, because one reader wants a shortlist and the other wants criteria. Merging them produces a page that half-serves both and ranks for neither. The test is not word overlap but what a satisfied reader would leave with: a decision, or an education. Different answers mean different pages, however similar the phrases look.
What do people ask most about this tool?
How many keywords per page?
One primary term and as many secondary variants as the page genuinely covers — commonly five to twenty for a thorough article.
What is keyword cannibalisation?
Two or more of your pages targeting the same intent, so search engines split signals between them and neither ranks as well as one consolidated page would.
How do I know if two keywords need separate pages?
Search both and compare the results. If the top results are largely the same pages, one page can serve both.
Do I need to rewrite old pages once I've built a cluster map?
Usually, yes for the pages the map identifies as overlapping. Consolidating two thin, competing pages into one thorough one is normally faster than writing something new, and it tends to produce the largest single ranking gain of anything on the map.
