I understand why EPC is important for a landing page. It shows how good is the landing page in convincing visitors to buy. But isn't the EPC for different banners that land on the same page meaningless? Isn't CPM and even CTR is better measure effectiveness of different banners of the same company?
Sorry. I don't understand your answer. What I am trying to say is that EPC shows the effectiveness of the landing page. CTR shows the effectiveness of the banner. CPM is combination of these two. Does this sound correct? If it is, I would like to see CTR and CPM when I display the list of advertisers.
