Adalysis will alert you if you have duplicate ads in the same ad group. You'll see the alert on your Auditalerts screen. Click on it for a list of ad groups or to automatically pause lower-volume ads.
Choose View duplicate ads to select and pause individual ad groups. You can also click on an ad group name to create a new ad.
Alternatively, you can create ads for multiple ad groups at once. Simply select your ad groups and choose an option from the Tools > Create ads menu.
