How many keywords should you target in a single ad group?

The number of keywords that you should target in a single ad group can vary depending on the specific goals and structure of your Google Ads campaign. However, a common recommendation is to include 15-20 keywords per ad group. This range allows you to create highly targeted ad copy and landing pages, while also giving you enough keywords to generate a significant amount of ad impressions and clicks.

It's important to note that including too many keywords in an ad group can lead to poor targeting and lower click-through rates. This is because the ad copy and landing pages may not be closely related to all of the keywords, which can confuse users and reduce the relevance of the ads.

On the other hand, including too few keywords in an ad group can limit the reach of your ads and make it difficult to achieve the desired level of impression share.

In general, it's a good idea to aim for a balance of keyword specificity and coverage in each ad group. This will help you to create targeted, relevant ads that are more likely to generate clicks and conversions.
