Adsense stats info with WP

I run my main site with wordpress. I install a few of Adsense block in my page template and give them channels like “top”, “right” and “in-artcile.”

The problem is a few days this month already I’ve gotten 100+ clicks from the top channel but I can’t tell which page they’re from. WordPress uses php templating so I layout the adsense code within one file and the articles use that template and create many pages. SO the only changes I can make to the code is in that one template file.

Without creating a new channel for each artcile I make, how can I track specific channels from specific pages?
