My CPM has been steadily dropping the whole month of February. What are all the possibilities that could be causing this? Is there anything I can do about it? I would appreciate any infomation/opinions/suggestions. Thanks!

Geez, so many variables. For example, let's say that you have AdSense on Valentine-centric pages. In the early part of the month, those clicks would likely be worth a lot more than the end of the month.

Just a thought.
