There’s a wP7 control called adrotar that works with a few ad providers however in past i couldnt get it to work. Recently i came across a more recent control called unified ad control – http://wpunifiedad.codeplex.com/ The premise like adrotar is to maximise ad revenue by giving user the option to customise ad provider per country. Eg. In US you could have a set of ad providers that give best ePCM for US. In UK, you can change those to ones that give deal for UK ads – you get the idea.
I tried it yesterday and with the help of its creater Mark, http://mark.mymonster.nl i have it working. I have modified the non US countries to use a mixture of ad provider excluding pubcenter, leaving pubcenter for US only. Only time will tell how things go.
