What is the main benefit of using negative keywords in a Google Ads campaign?

Using negative keywords in a Google Ads campaign is primarily beneficial because they help to exclude irrelevant searches from triggering your ads. By implementing negative keywords, advertisers can ensure that their ads are not shown for specific terms or phrases that do not align with their products or services. This targeting reduces wasted ad spend on clicks that are unlikely to convert, improving the overall efficiency of the campaign.

For instance, if a business sells high-end running shoes, it might use negative keywords like "cheap," "free," or "used" to prevent its ads from appearing to users searching for lower-priced options. This not only enhances the relevance of the traffic to the ads but also leads to better click-through rates, improved Quality Scores, and ultimately, a higher return on investment.
