Much of the adwords mobile app traffic is junky and low converting and sometimes you’ll want to exclude it altogether. The easiest way to do accomplish this is to block the domain
adsenseformobileapps.com. It’s a special domain that google uses to allow us to block mobile app traffic.
- Go to the particular adgroup or campaign you’d like to apply the exclude
- Click “Display Network” tab near Dimensions
- Click +Targeting Button
- Click Adgroup/Campaign Exclusion, then click Placement
- On Placement copy/paste
adsenseformobileapps.comand save it.
