What does eCPM even mean and how is it determined?
eCPM isn't something you should really be basing anything off of. It is simply how much you've made divided by the number of impressions you've had. If you switch your time periods up the eCPM changes because your impressions change (last week vs all time, for example).
It stands for... estimated cost per mille or something. So how much you make per 1000 impressions. But I must reiterate: it's not like the eCPM is magically generated then you make money based off of that. Mysterious variables determine how much you make in cents, then the system takes that and does a very simple division to report your eCPM.
At least this is how I've construed it after mucking around a tad. Anyone in the greater know feel free to correct me.
