Ad Rotation

Ad rotation is a setting provided in a campaign that will automatically rotate ads within your ad group on the Search and Display Networks. One can choose this setting when they have two or more ad copies within an ad group. This rotates each ad and helps the user choose the best performing ads. This also helps increase ad relevancy and improve the CTR & quality score of the keywords.
