How it works What the Keyword Gap Finder does

Returns the lines from List 1 that do not appear in List 2 — your keyword gap, or your exclusive wins if the lists are swapped.

3 steps How to use the Keyword Gap Finder

  1. Paste your list into the box above — one item per line, and the second list into its own box. Keyword exports, crawl exports and spreadsheet columns all work.
  2. Check the settings and adjust them to your job — the result updates as you type.
  3. Copy the result and paste it wherever it needs to go. Nothing is uploaded, so client and confidential data stay on your machine.
