Keyword combiner

The tool takes one item from each list in every possible combination (the Cartesian product) and joins them with the separator:

List 1	List 2	List 3
cheap	bike	Chicago
used	scooter	Denver
women's

gives 3 × 2 × 2 = 12 combinations: cheap bike Chicago, cheap bike Denver, cheap scooter Chicago … women's scooter Denver.

The exact number of combinations is shown at the top, even when it is huge. Up to 50,000 lines are listed; if there are more, you'll see a warning and only the first 50,000 are shown. Add up to four lists with + Add list.

• Separator between parts. Space by default; quick buttons for comma, semicolon, tab, dash, equals or nothing, or type your own.
• Format. Plain text, "phrase match" in quotes, or [exact match] in square brackets, the notation used in Google Ads and Microsoft Advertising keyword lists.
• Every list is optional. Also produces the shorter variants that skip one or more lists: bike, cheap bike, bike Chicago and so on. This is handy when a modifier like a city is not always part of the search.
• Merge duplicate items. Removes items repeated within a list, so you don't get duplicate combinations.

Empty lines are ignored.

Search ads campaigns often need every combination of a modifier, a product and a location. Instead of typing them by hand or writing spreadsheet formulas, paste the parts here:

1. List 1: modifiers like cheap, best, used.
2. List 2: products like road bike, mountain bike.
3. List 3: locations like Chicago, Denver, or intents like for sale, near me.

Choose phrase or exact match, copy, and paste the list into your ads editor. Turn on Every list is optional to include the shorter versions without the modifier or the location.

Keep the lists short and relevant: combinations multiply quickly, and many will have no real search volume. Check them in your keyword planner before you build ad groups around them.

Every list you add multiplies the total: four lists of ten items each already give 10,000 combinations. Some ways to keep it useful:

• Start with the two lists that matter most, then add a third only if it adds real variations.
• Use Merge duplicate items so a repeated word doesn't double the output.
• Remove combinations that make no sense afterwards with filter lines, for example everything that contains used together with new.

• Product variants: sizes × colors × materials (Small Red Cotton).
• Test data: first names × last names to create sample users.
• Brainstorming names: prefixes × roots × suffixes.
• File names or SKUs: use a dash or nothing as the separator.

For pairing lists line by line instead of in every combination, use merge lines. For mathematical combinations or permutations of a single set, use the combination generator or the permutation generator.
