What the Keyword Combiner does

The Keyword Combiner produces the full cross product of two lists — every entry in list A joined to every entry in list B — which is the standard way to build structured keyword matrices.

How it works

Both lists are split and trimmed, then paired in order with your chosen separator. The result is capped by the limit setting so large lists cannot lock up the page.

  1. 1Paste the first list, one entry per line.
  2. 2Enter the second list separated by commas.
  3. 3Pick the join character.
  4. 4Set a sensible cap on results.
  5. 5Generate, review and export.

Worked example

['summer', 'winter'] combined with ['sale', 'outfit'] gives 'summer sale', 'summer outfit', 'winter sale', 'winter outfit'.

Who uses it

  • Building city + service keyword matrices
  • Pairing product types with attributes
  • Creating season + campaign term combinations
  • Generating hashtag bases before conversion

Best practices

  • Keep both lists short — output grows multiplicatively.
  • Use the hyphen join when the output feeds URLs.
  • Delete nonsensical pairs before exporting.
  • Cluster the survivors to spot themes.

Honest limitations

Combination is mechanical: many pairs will be meaningless, and the tool has no way to judge which ones matter.

Frequently asked questions

Why is my output truncated?
The result cap stops runaway lists. Raise the limit if you need more.
Can I combine three lists?
Run twice: combine A and B, then feed that output back as list one.
Is order preserved?
Yes, results iterate list A in order, then list B within each entry.
