When you all calculate your "CTR" do you look at Clicks per page
When you all calculate your "CTR" do you look at Clicks per page (which could have 1-3 ad blocks), Clicks per ad block (which could have 1-5 ads) or Clicks per ad, which would ideally be the lowest common denominator. Which does G look at to determine if your site CTR is too high? Each is manipulable to an extent in various ways, but which to manipulate?
Personally, I think I would be getting worried well before the 10% level that there was something wrong with my site to cause such a high number to want to click on ads.
this whole conversation is pointless
