Google Enables Language and Location Setting at Ad Group Level in Demand Gen Campaign

Google convinces that setting the language and location at the ad group level helps ensure that the budget is actually placed where the ads perform best.

Google still recommends setting the language and location at the campaign level in cases where targeting ads must be within a certain radius of a location – these can not be changed once the campaign has been published. Please also note that setting the location and language at the campaign level will clear these settings assigned at the ad group level.
