iAd income - real life milestones for developers

I'm doing some research in to iAd to decide whether or not to keep it in an upcoming update. I didn't ever really put any effort in to marketing with the current version of the app so I don't really have any idea of what to expect per x amount of impressions and taps.

I'll introduce the app later in time when it's in the store and also to keep the thread relative to iAds.

If people could provide real life data and their thoughts on iAd I wild really appreciate it!

By the way I know that there are several threads on this type of thing but there are so many different numbers of impressions and tap through for developers I think it will only help having another thread on this subject.

Thanks in advance!

What if the app makes use of third party data where charging for the app isn't morally or legally allowed? Or user generated data like Facebook or Twitter? Although I do agree the type of adds in the examples are very different from a banner attached to the bottom of the screen...

I agree ads aren't attractive but Apple does a great job with them, especially after they've been tapped on.

Maybe it's worth me looking in to a paid ad-free app and a free alternative which does include them?
