Question about monitoring ad-sense earnings per page.

I have an idea for a small start-up that I'm interested in, which will allow me to allow users to upload content to my page and earn money via ad-sense. This page is going to be niche specific and already have a decent amount of traffic to help get said product noticed. All of said products will be in a specific niche. Think of this such as a large gaming portal, in which I offer ad-sense earnings to the games that want it. To do this I would have to monitor the earnings for each page. What's the best way to do so?

Google's tools for viewing earnings aren't very great, and I'm trying to find a way to automate this process so I can keep statistics updated for people in pseudo real-time. I have a programming background so creating an automation shouldn't be too hard once I find the method of gathering the earnings easily.

I've been searching for a solution too. One that doesn't involve linking adsense to analytics. I think an easier solution for you might be just letting users add their own adsense id in their profile and have that area rotate your adsense and theres at whatever % of impressions you want to give them. Then you really don't have to do anything, or worry about sending out payments.

You may track it via Google Analytics as they have an option to see where you make money.
