not sure what you mean exactly, but adsense provides detailed stats in your panel..when you want to see which pages perform, just make different ads for each page and see what ad has more clicks
so just create ads for each article:
ad250x250#1 for article #1
ad250x250#2 for article #2
then compare the stats in the admin panel
I need to see which article generates clicks and which not. I want something like this:
www.site.com/article1 - generate 30 adsense clicks
www.site.com/artcile2 - generate 10 adsense clicks
and so on.
