Can anyone tell me what is up with my eCPM going so much lower from one month to the next? also, should i just go ahead and drop adsense and use some other program? October - 1230 clicks - $2.05 ecpm - $198 for the month November - 1400 clicks - $1.04 ecpm - $140 for the month and now december is going WAY worse. I am only getting $0.70 ecpm. what should i do??
