Google announced that Ad group level mobile bid adjustments are now available in many Google AdWords enhanced campaign accounts, with more accounts being added.
Another change is that you can now set bulk bid adjustments for locations, dayparts and devices.
These new changes are also active through AdWords Editor, for those AdWords customers using the editor to create, edit and manage their AdWords ads.
These changes are being made in hopes that greater flexibility will increase CPC values when AdWords customers can easily increase bids on segments that are performing well for them.
