Frequently asked questions

How many lists can I combine?

You can combine up to 4 keyword lists at once. Each list can contain as many keywords as you need.

What is the best separator for SEO?

Use spaces for keywords and ad groups, since that is how people search. Use hyphens when you are building URL slugs, and None to join words into hashtags or domain ideas.

Can I use this for Google Ads campaigns?

Yes! Keyword combiners are a staple for PPC managers. Generate your keyword variations and import the CSV directly into Google Ads.

Is there a limit to the number of combinations?

There is no hard limit, but extremely large sets (10,000+) may take a moment to render. We recommend keeping lists focused for best results.

What is keyword permutation?

Permutation means generating every possible ordering of terms across multiple lists. For example, combining 'buy, cheap' with 'shoes, boots' gives you 4 unique keyword phrases.

Is the keyword combiner free?

Yes. The keyword combiner is free, has no signup and runs in your browser, so you can combine keywords as often as you like.

How is the number of combinations calculated?

Multiply the number of keywords in each list. Three modifiers, four products and two locations give 3 × 4 × 2 = 24 combinations.

Can I export the combinations?

Yes. Copy them or download a file you can paste into Google Ads, a spreadsheet or your keyword tool.

Should I check volume for combined keywords?

Yes. Many combinations have little or no search volume. Paste the best ones into the Keyword Research tool to see which are worth targeting.

What are good lists to combine?

A common setup is modifiers (best, cheap, free), a core product or service, and a location or audience (near me, for startups).

Do empty lines count?

No. Blank lines and extra spaces are ignored, so you can paste lists straight from a spreadsheet.
