Re: Ad groups with no ads
Usually there is a link in that message which will send you to the ad group with that problem.
If the link does not work, I would check deleted campaigns where Ad Groups are kept enabled but Ads are also deleted inside them so you may have the following structure :
- Campaign1 - deleted
- Ad Group 1 - Enabled
- Ad1 - deleted
If you cannot find this structure either, close the warning from the X sign to the right, wait for a few days and chances are , the warning may dissapear.
