Today I have seen that my eCPM is way down from what is use to be. I also have several clicks that I didn't get paid for and that haven't happened before. Well, it might have but if it has I haven't seen it. Anybody else seen a huge drop today?
I never give a damn to eCPM. Just concentrate on improving your CTRs only and leave the rest to destiny.
Not unusual... i dont know what ads you have on your site etc.. what niche etc.. but this is not unusual. But i agree that its getting worser with AdSense. Better focus on affiliates or other systems.
