Keyword Combiner
Combine two or three lists of words into every keyword permutation. Free tool for keyword research and paid search campaigns.
Independently verified for accuracy
Calculator by Toolsloft ↗Enter up to three lists of words and get every combination for keyword research or ad campaigns. It is the fast way to turn buy, rent and car, van into buy car, buy van, rent car, rent van. Pick the separator, such as a space or hyphen, and empty lists are simply skipped.
How this is calculated
The tool computes the Cartesian product of the non-empty lists, keeping list order so the first list varies slowest and the last varies fastest. Each term is trimmed, blank lines are dropped, and combinations are joined by your chosen separator, one per line.
How to use
- Enter your first list of words, one per line.
- Add a second and optional third list to combine with it.
- Choose a separator and copy the combined keywords from the output.
Examples
- Two lists:
buy/rent x car/bike = 4 phrases - Custom separator:
join with a hyphen
FAQ
- How many lists can I combine?
- Up to three. Any list you leave empty is ignored, so you can combine two lists or expand a single list on its own.
- What order are the combinations in?
- The first list changes slowest and the last list changes fastest, so all combinations for the first term appear before the next.
- Can I use it for paid search?
- Yes. It is handy for building broad keyword sets, though you should still review the output and remove combinations that do not make sense.
