If you monetize your Windows Phone (and Windows 8) apps with ads you probably know not to rely on a single ad network. Some do better in one region and have nothing to show in all others, some pay more in some countries but less in the others, etc. And the fill rate is never 100%. So to make sure you utilize your ad space to the max you use multiple ad providers.
It’s not too difficult to implement a system that will switch from one ad provider to some other when there’s no ad to show. But if you want to do it really well you’d probably need to have different defaults for different locales. And to make things more complicated performance of different ad networks changes regularly. So you don’t want to hard code any of these settings into your app and issue an update whenever market situation changes. You can still implement an intelligent system like that yourself, but why reinvent the wheel?
There’s an open source project called Ad Rotator which can do all of the above and more for you. We’ve interviewed lead contributors to the project – Gergely Orosz and Simon Jackson on the latest episode of AppBizDev podcast. Check it out and make sure you subscribe in Zune, iTunes or any other tool to get new episodes automatically.
And, btw, if you have some music skills in addition to your awesome dev skills, you can get a MILLION free ad impressions on AdDuplex network by contributing a theme music to the podcast. Check out more details here.
