I use AdMob to promote my apps.
Right now, in AdMob management board I have a Promote tab and it is way too easy to add a new ad by specifying an ad image of my own app and that ad will be advertised in Google's network.
Plain and simple.
However, I got a notification about the retiring of the Promote tab and its replacement will be the Campaigns.
I still intend to promote my own apps so I checked what to do.
I got confused as the Campaigns seem to be consisting only of lending my ad units.
I can set goals (click or percentage - I don't even understand how a percentage could help me promoting my apps...) and specify my ad units in my apps. What if I don't have an app with an ad unit? Then I can't create a campaign?
It seem, I can't continue unless I select one of my ad-containing app. Why?
Why did they take away the promotion? What should I do about this? Should I select my other apps?
