It seems that Adsense program is not providing statistical information on revenue to site owners because this data could be used in a way they do not want.
For example, they do not want to show which page generate which revenue because of this issue.
But in large sites with several different sections this issue became against publisher success, because I would improve the sections that generate more revenue, but I am playing blind.
At least they could give a code to separate bunchs of related pages, for example a group of at least 20 pages with same special ID code could be allowed to be identified in revnue stats, so I can have a revenue map, what kind of bussines lack of a revenue source identification?
I didn't really get it until the other day I was searching for some info (the exact topic escapes me, but it was probably fuzzy widgets) and wound up on one of these auto generated pages. A pure adsense vehicle, and 100% free of actual content.
If G gives you the whole stat picture, that kind of crap will swamp the real pages in a heartbeat.
As far as a revenue map, I think that's a damned interesting idea really. But in a way I think G is doing me a favor witholding that detailed statistical info--I'd just spend time slicing and dicing it in Excel and optimizing my revenue instead of doing what I do now (mainly writing articles I think people want to read).
Having just lately stuck adsense onto a site mainly made up of stuff I though people would want to read, I was real surprised just how well that strategy pays off.
