What Is a Keyword Grouper?
Keyword research gives you a long, messy list. To use it in Google Ads you need small groups of closely related keywords, so each ad group can have ads and a landing page that match what people searched. Sorting hundreds of keywords by hand takes hours.
This keyword grouper does the first pass in seconds. It finds the words and word pairs that keywords share, such as a brand, an audience or a price point, and builds a group around each one. Words that appear in nearly every keyword, like your main product, are skipped so they do not swallow the whole list.
How to Use the Keyword Grouper
- Paste your keywords, one per line. Add search volume after a tab or comma if you have it.
- Pick the smallest group size. Keywords that do not fit any group go into Other.
- Add words to ignore if a group is too broad, for example your product name.
- Review the groups. Change the options until the themes make sense for your account.
- Download the CSV and import it into Google Ads Editor, or copy the groups into a sheet.
How the Grouping Works
| Step | What happens |
|---|---|
| Clean | Keywords are lower cased, duplicates and symbols are removed |
| Count | Every word and word pair is counted across the remaining keywords |
| Pick | The most shared theme becomes a group. Pairs beat single words on a tie |
| Repeat | Grouped keywords are removed and the next theme is picked until none are left |
Each keyword lands in exactly one group, so you never end up bidding on the same keyword in two ad groups. With singular and plural treated as one word, "mens" and "men" or "shoe" and "shoes" stay together.
Tips for Tight Ad Groups
- Aim for one theme per ad group. If you cannot write one headline that fits every keyword, split the group.
- Watch the Other group. It often holds unique long tail keywords worth their own group, or ones to drop.
- Use volume to prioritise. Start with the groups that have the most searches and a clear landing page.
- Brand and price groups convert differently. Keeping them apart helps Smart Bidding and makes reports clearer.
Plan Your Account Structure
Find the right keywords with the best keyword research tools, weigh effort and reach in search volume vs keyword difficulty, and decide on structure with Search vs Performance Max. Then format each group with the keyword match type generator.
Frequently Asked Questions
1How many keywords should an ad group have?
There is no fixed rule, but most well run accounts keep about 5 to 20 closely related keywords per ad group. What matters is that one set of ads and one landing page fit all of them.
2Why are some keywords in the Other group?
They do not share a theme with enough other keywords to reach your smallest group size. Lower the minimum, or give the best of them their own ad group.
3Can I group thousands of keywords?
Yes. Everything runs in your browser, so a few thousand keywords group in a second or two on most computers. Very large lists may take a little longer.
4Does it work for SEO keyword clustering?
It groups by shared words, which works well for planning pages and topic clusters too. It does not compare live search results, so check that each cluster really shares one intent.
