So, I haven't been using AdSense for long but I've been noticing that my eCPM is jumping all over the place without any type of consistency. One day its $19.86, next day its $0.01, then it jumps up again. Is there any tips on what could be causing this? Is it normal? :0 Its kind of out of control. Thanks.
it is normal. I have noticed that higher is the number of visitors that a site gets, more stable the eCPM is. e.g. for one of my sites which gets around 1500 uniques everyday, the eCPM remains around $2.50.
