Your ad is more likely to perform better and continue running successfully if it is being displayed to the users who are most likely to be interested in your product or service. Because of this, we recommend targeting your ads to smaller, more specific groups of users at one time. This allows you to write ad text that is more personalized, making your ad more appealing to the users you are reaching. It also enables you to generate better insight into your advertising performance, and allow you to find the most effective ad.
