In the last month eCPM droped by 70%.
Why?

[greatstart]

I do not know why, but sometimes my eCPM drops like 35% from one day to the next. I never had a drop of 70%, which would be very very bad.

Why?

Read the many, many, many, many, many, many, many past threads on the topic of falling eCPM, earnings, etc.

You won't get any definitive answers, though, because the reasons for a drop (or increase) in earnings can be very complex.
