Find Keyword Gaps Now

Find costly keyword gaps and take action

No matter where you are in your research stage, SpyFu’s keyword gap tool can offer answers. It helps with both market research and specific advice for individual domains.

Market Research

• All Keywords: Keywords bought by any competitor
• Core Keywords: Keywords that all listed competitors buy

Advice for the Specific Domain

• Consider Buying: Gaps where your competitors buy, but you don’t
• Potential Ad Waste: Keywords you buy, but these competitors don't

Your competitors aren’t directly telling you which keywords they trust, but their habits are loud and clear. They vote with their ad dollars on the top keywords to trust. One competitor buying a keyword could be a test. When two or more buy the same keyword, you should look into it, too.

Gaps could reveal weak keywords too

If none of your competitors buy a keyword that you buy, you might be losing money on an unprofitable term. Look at the keywords your ad appeared on, but your competitors didn't buy. Then, add them to the negative match to stop bad clicks from wasting your budget.
