I am running a video blog, approximately 3,5k UV per day. Right now I am using Cliksor and Adbrite combination. Clicksor Interstitial Ad and Popup-under. Adbrite Text & banner ads and full page ad. Right now earning like $3 per day, used to be like $5-6 with same traffic. What changes I should made in clicksor and adbrite? Cannot use CPA Lead cause the main traffic is coming from Sidereel.
