Keyword Clustering Tool
Paste your keyword list, from Keyword Planner for example: the tool sorts it into ad groups, one group per shared word, and gives you each group ready to copy or upload.
Google Ads organizes a Search campaign into ad groups: ads and keywords gathered around the same theme. The help page takes the example of an ad group for dress shoes, targeting people searching for dress shoes.
Grouping worked out in your browser, nothing is sent. Export: Keyword and Ad group columns, with the quotation marks or brackets of the chosen match type, as in the keyword spreadsheet upload described by Google Ads Help, read on 24 October 2026.
Your Groups Are Ready. What About Your Ads?
An ad group is worth the ads that pick up its words and the page that answers them. Google Ads campaign builds start from there.

How the groups form
The word shared by the most keywords forms a group Then the same rule on the remaining keywords
Each keyword is split into words. Filler words (of, for, with) and the words you choose to ignore are removed, and singular and plural forms are matched. The tool then takes the word shared by the most keywords, makes it a group, and starts again on what is left, until no word brings enough keywords together.
Whatever shares no word with another stays under “No shared word”: these are often separate searches that deserve their own group or an exclusion.
Two uses
- Building a campaign: paste the ideas from Keyword Planner, ignore your product name, and each group becomes an ad group with its own ads.
- Tidying an existing account: paste the keywords of an ad group that has grown too wide to see the themes mixed inside it.
Frequently asked questions
How do you group keywords in Google Ads?
By theme: an ad group gathers ads and keywords around the same subject, as Google Ads Help shows with an ad group for dress shoes. The tool suggests these themes from the words your keywords share.
How do you upload the groups to Google Ads?
Export the CSV: it carries the Keyword and Ad group columns that Google Ads Help describes for uploading keywords with a spreadsheet. Quotation marks give phrase match, brackets give exact match.
Is my list sent anywhere?
No: the grouping is worked out in your browser, and your list never leaves your page.
