What is keyword clustering?
Keyword clustering groups keywords that belong on the same page. A flat list becomes a content plan: one URL per group, instead of a separate thin page for every near-duplicate. This tool groups a pasted list by shared topic words and suggests a page type for each group. It stores nothing.
What is a keyword cluster?
A keyword cluster is one group of phrases that should target a single URL. The phrases share a subject, such as "notion", even when the wording changes. A phrase with no shared subject stays in its own cluster. The suggested page type is a separate label, read from how the phrases are worded.
What is a keyword clustering example?
Paste the phrases below and this page groups them by the subject word, then labels a page type from the wording. "vs" and "alternatives" mark a comparison. "how" marks a guide. "software" and "best" are ignored, so they cannot glue unrelated topics together.
| Pasted keywords | Why they group | Page type |
|---|---|---|
| notion vs obsidian, notion alternatives | They share "notion" | Comparison |
| how to take meeting notes | No shared subject with the others, and "how" marks a guide | Guide |
| crm software, best crm for startups | They share "crm". "software" and "best" are ignored | Landing page |
How do you cluster keywords?
Paste the list, one keyword per line or separated by commas, and submit. Read each group as one future URL. Keep a group when you can publish that page, and skip a group that is only a near-duplicate of a page you already have. This run does not look up search volume, so do the research first if you still need demand numbers.
How does this keyword clustering tool group keywords?
It groups keywords that share a topic word, including a short list of expansions such as "customer relationship management" with CRM and "search engine optimization" with SEO. Words such as "best", "software", "platform", "vs", and "how" do not create a group. If A shares a word with B, and B shares a different word with C, all three land in one cluster. The paid pipeline adds a second check: whether the phrases return the same Google results.
What page type should a keyword cluster become?
The label is a vote across the phrases in the cluster. Each phrase is read for a signal, and the most common signal wins. A phrase with no signal counts as a landing page. The label is a suggestion for the page you would build, not a rank.
| If a phrase includes | Suggested page type |
|---|---|
| vs, versus, alternative, compare | Comparison |
| how, what, why, guide, tutorial, tips, steps | Guide |
| tool, calculator, generator, checker | Tool |
| template, sample, or example | Template |
| statistics, data, report, trends, benchmark | Data |
| about us or company profile | About |
| none of those signals | Landing page |
What is the best keyword clustering tool?
There is no best keyword clustering tool for every team. Match the tool to the job. This page is the free option when the list is already in hand and you want groups plus a page type, with no account. Keyword Cupid is a separate clustering product, not a default winner. A research suite is the wrong tool if the only missing step is grouping.
| Job | What fits |
|---|---|
| Group a list you already exported | This page |
| Group by live Google results, then ship the pages | Orchory's paid pipeline |
| Find volume before you group | A keyword research tool, then this page |
What's the best tool for keyword clustering?
The best tool for keyword clustering is the one whose method matches the list. Shared topic words are enough to turn an export into page groups, which is what this page does. Live search-result overlap is the stricter test when two phrases look related but Google treats them as different pages. That check is not part of this free run.
Is Keyword Cupid the best keyword clustering tool?
No. Keyword Cupid is a keyword clustering product, and it is not the best tool for every list. Use it when that product's workflow is the one you already run. Use this page when you want groups and a suggested page type from a pasted list, free, with nothing stored. Neither choice looks up search volume for you.
What is the difference between keyword research and keyword clustering?
Keyword research finds the phrases people search and estimates demand. Keyword clustering decides which of those phrases belong on the same URL. A research export is still a flat list. Paste it here to turn it into page groups. This page does not add volume, difficulty, or rank.
What is SERP keyword clustering?
SERP keyword clustering groups phrases that return the same Google results, on the idea that Google already treats them as one topic. This free tool does not fetch those results. It groups by shared topic words instead. Orchory's paid pipeline is the run that adds live result overlap and then scores which cluster to build first.
How many keywords can I cluster at once?
Up to 300 keywords per run. Each keyword is capped at 120 characters. Anything over 300 is skipped, and the page shows how many were left out. Duplicates are dropped. One per line and comma-separated values can be mixed in the same paste.
Is this keyword clustering tool free?
Yes. Clustering needs no account and no card. The page shows the first three clusters immediately. Entering an email reveals the rest of the groups on the page. The CSV of every cluster from that run does not require an account. Nothing is stored.
Can I download my keyword clusters?
Yes. After a run you can download a CSV with no account. Each row is one keyword, with the cluster name and the suggested page type. The file includes every cluster from that paste, up to the 300-keyword cap, including groups that are still hidden on the page.
What are the top 5 keyword research tools?
These five are widely used because they do different jobs, not because one ranking makes them the top five. Research tools find the phrases. This page is the next step: group the shortlist so each cluster becomes one URL.
| Tool | Use it for | Cost to start |
|---|---|---|
| Google Keyword Planner | Keyword ideas and search-volume estimates | Free with a Google Ads account |
| Google Search Console | Queries your site already appears for | Free |
| Ahrefs | Keyword and backlink research | Paid |
| Semrush | Keyword and competitor research | Paid |
| Orchory keyword tool | Intent, volume, difficulty, and an opportunity score from a topic or URL | Free to start, no account |
Is Google Keyword Planner free?
Yes. Google Keyword Planner is free once you have a Google Ads account. Opening it does not require a campaign, and Google does not charge for the planner itself. Volume is an estimate, and accounts that have not spent on ads often see a range instead of a single number. Planner does not group keywords into pages. Paste the export here when you want clusters.
Clustering decides which page each keyword belongs on. See the same clustering running end to end in an auto SEO tool for developer teams, or how it compares with clustering inside a marketing suite in the Semrush alternative for teams shipping in git.
