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.
