Create a shopping campaign
Add negative keywords to a shopping campaign
Negative keywords can help you reach the most interested customers, reduce your costs, and increase your return on investment. When you add terms as negative keywords, your ad won't show to people searching for those terms.
You can create negative keywords at the campaign level or the ad group level. Negative keywords at the campaign level apply to all ads in the campaign, while negative keywords at the ad group level prevent specific ad groups from showing ads for specific queries.
