Hello,

I was evaluating a site I bought a few months ago and (not sure it matters, but it is the new Adsense interface) and found something quirky.

I have 3 ad units on every page, two 468x60 (one on the left one on the right down the page) and one 120x600 at the bottom of the page content.

The site has reasonably good traffic (20k uniques a day), however when I generate performance reports it shows a lot of page views (which I believe is accurate) for only 1 ad unit (one of the 468x60), and very little for the other two ad units. Please note I don't have any custom channels setup at the moment (was planning to optimize soon).

Also for the other 468x60 ad unit, although it is showing very low page views it has more or less equal clicks as the one that shows the correct/much greater page views.

Any idea why this is happening? Above any other issues it is making it very hard for me to really evaluate performance CTR, etc of the ad units individually and accurately. All help really appreciated.
