Hello friends,

what are negetive keywords?

Negative keywords improve the performance of your AdWords campaigns and improve your relevance.

When you add "free" as a negative keyword to your campaign or ad group, you tell AdWords not to show your ad for any search containing the term "free." On the Display Network, your ad is less likely to appear on a site when your negative keywords match the site's content.
