You can use advertiser groups to bundle advertisers so that you can view reports on the whole group at once.
You might use advertiser groups to organize multiple brands under one corporation, or to sort them into different groups for each team at an agency (one advertiser group for each bundle of advertisers that a team works on).
Create and apply advertiser groups
Click Advertiser in the top navigation bar and select or create an advertiser.
Under Identification, either choose a group from the Advertiser group menu. To create a new group, type a new name in the field and hit the RETURN key.
