I noticed that CPM ads have the old style "Ads by Google" link while the CPC ads have the new image with "Ads by Google" (logo). Well i'm not sure if those ads are really CPM, that's why i post this - does your CPM ads display in the "old fashion" too?

yes the second one is CPM coz it's using the whole block that means it's targetted. People sometimes confuse video and image ads as CPM, most of the times they are not CPM, they can be cpc and cpm both
