I was just wondering if anyone here uses AdWords as well as AdSense, and knows how the channels work on the other side.

Say I've got a page with an advert at the top and bottom. At the moment I have a channel for each one, even though it's the same page, because Adsense lets you show where it is positioned. So I figured that an Adwords person might want to target a particular position instead of just the page.

Is that a total waste of time?

I was thinking I might just have one channel instead, which will bump up my impressions on it, making the numbers look a bit more impressive
