Keyword Clustering Tool
Turn a long keyword list into topic groups, so you know which keywords belong on the same page and which need their own. It runs in your browser.
Why cluster keywords?
Keyword research gives you hundreds of phrases, but many of them mean the same thing to a searcher and to Google: “how to clean running shoes” and “how to wash running shoes” should be answered by one page, not two. Clustering groups those variations together so you can plan one strong page per topic, avoid creating pages that compete with each other, and see which topics have the most total demand.
How this tool groups keywords
Each keyword is reduced to its meaningful words: common filler words are removed and simple word forms are merged (“shoes” and “shoe”, “cleaning” and “clean”). Keywords are processed from the highest search volume down; each one joins the existing cluster whose main keyword it shares the most words with, or starts a new cluster. The highest-volume keyword names each cluster, so it’s usually the best primary keyword for the page.
- Loose builds broader topics, good for planning categories and hub pages.
- Balanced suits most blogs and stores.
- Strict keeps only very close variations together, good for deciding exact page targets.
Search intent labels
Each cluster gets a label based on the words its keywords contain: Informational (how, what, guide), Commercial (best, vs, review, alternatives), Transactional (buy, price, cheap, deal) or Local (near me). Intent tells you what kind of page to create: a guide, a comparison or a product/category page. Two clusters with different intent usually need different pages even if their words overlap.
Limits to know
This is word-based clustering. It’s fast, free and private, but it can’t know that “sneakers” and “trainers” mean the same thing, or that two different-looking phrases return the same Google results. Professional SERP-based clustering compares live search results and costs money per keyword. For most sites, word-based clusters plus a quick manual check are enough: skim each cluster, move any keyword that doesn’t fit, and look at the “unclustered” list for ideas that deserve their own page.
From clusters to content
- Pick the largest clusters that match your goals.
- Use the cluster name as the page’s main keyword in the title and H1.
- Cover the other keywords in the cluster as subheadings or FAQs. Find extra angles with the Long-Tail Keyword Ideas tool.
- Link related clusters together to build topical authority.
How to use the Keyword Clustering
- Paste your keywords (one per line, with volume if you have it) or upload a CSV/Excel export.
- Choose Loose, Balanced or Strict grouping and click Cluster keywords.
- Plan one page per cluster and download the CSV for your content plan.
Frequently asked questions
How many keywords can I cluster?
Up to 5,000 at a time. Everything runs in your browser, so large lists take a few seconds on older devices.
Is this the same as SERP-based clustering?
No. It groups keywords by shared meaningful words. SERP-based tools compare Google results for every keyword, which is more precise but paid. Word-based clusters are a fast, free first pass.
Where do I get a keyword list?
From Google Search Console (Performance → Queries → Export), Google Keyword Planner, or SEO tools like Semrush and Ahrefs. Our Long-Tail Keyword Ideas tool can also give you a starting list.
