In the admob site reporting, there is a column with “CPM Imps”.
I notice that one of my app has averagely 200++ “CPM Imps” per day. In the last two days, the “CPM Imps” for the app rise to 600++. The revenue per day, CTR, eCPM has not changed much.
For others of my app, the “CPM Imps” is always less than 30.
Is there anyone can tell me what is the meaning of “CPM Imps” or how it is calculated from any datas.
Thanks a lot.
