There has been a lot of information flying around about ads in apps these days. Microsoft recently updated PubCenter reporting to include fill rates and number of requests for ads. Dvlup recently partnered with AdDuplex to in its reward program. With all of this hype, I thought I would talk about a common problem with placing ads in apps. That issue is keeping ads in the same location when rotating the phone. Most apps are Portrait apps and display ads either at the top or bottom of the app.
