If i compare the previous month and this month i notice that my earnings are almost half of the previous month . This month i had double the clicks than that of the previous month and despite that i have half of the earnings . The eCPM factor is almost same . What could be the possible reason ?
This has been happening to a lot of people. Has your content changed? Hmm, I don't know the exact answer you would want to have..
My months revenue is up compared to September. There are many variables to consider that can effect revenue. Perhaps the advertisers in your niche just aren't buying this month. I would not worry about one month's dip nor get too excited about one great month's revenue. Look at the trend over 6 months or a year. Is your traffic and revenue going up? If yes, keep doing what you are doing. If no, then re-evaluate and make changes.
