About the Negative Keyword List Builder

Every PPC account pays for some searches that will never convert, such as people looking for jobs, free versions or DIY instructions. This negative keyword tool takes a pasted list of search terms, highlights common wasteful words like free, jobs and DIY along with any words you add, and builds a deduplicated negative keyword list in the match type you choose.

It also shows which search terms each negative would block. That check matters, because an overly broad negative can stop good traffic too. Export the list and add it to a shared negative keyword list or campaign. Search term data stays in your browser and is not uploaded.

How to use it

  1. Export your search terms report and paste the terms into the tool.
  2. Review suggested words and add your own exclusions.
  3. Choose broad, phrase or exact match for the negatives.
  4. Check which terms each negative blocks, then copy the final list.

Frequently asked questions

What are negative keywords?

Negative keywords stop your ads from showing for searches that contain them. If you sell premium software, adding free as a negative stops ads appearing for searches such as free accounting software. They help focus budget on relevant searches. They can be added at campaign or ad group level.

How do negative match types work?

Negative keywords behave differently from positive ones and do not match close variants such as plurals or misspellings. A broad match negative blocks searches containing all its words in any order, phrase blocks that exact phrase, and exact blocks only that exact search. Add variants yourself where needed.

How often should I add negative keywords?

Review your search terms report regularly, more often when a campaign is new or uses broad match. Many advertisers check weekly at first and then monthly once the account settles. Shared negative keyword lists save time when several campaigns need the same exclusions, and they are easy to update as you find new wasteful terms.
