By tracking revenue and providing fallback content, you're monitoring and improving the financial success of your app. In this final chapter, you've done the following:
Accepted the Apple iAd Contract that is required to display live adverts in your apps
Activated live ads in each of your apps
Learnt the terminology used for tracking revenue
Viewed the revenue your apps are generating
Displayed fallback banner content when the iAd Network is unavailable
With these skills, you're fully able to embrace iAd, as both an advertiser and ad publisher. Good luck!
