In a Shopping campaign, what role do negative keywords play?

Negative keywords play a crucial role in a Shopping campaign by preventing certain searches from triggering ads. When advertisers add negative keywords to their campaigns, they specify terms that they do not want to be associated with. This means that if a search query contains any of these negative keywords, the ads will not be displayed for that search.

This approach helps advertisers optimize their ad spend by ensuring that ads are only shown for relevant searches. It minimizes wasted impressions on irrelevant queries, enhancing the efficiency of advertising budgets. As a result, negative keywords effectively refine audience targeting, leading to better overall campaign performance.

The other choices present scenarios that do not accurately reflect the function of negative keywords. For instance, negative keywords do not increase ad visibility or refine product descriptions, nor do they inherently increase response rates; rather, their main purpose is to exclude specific search terms that could lead to ineffective ad displays.
