my eCPM dropped from always over 1€ to now 0,3-0,5€ since the beginning of the new year.
My Impressions arent that high, but they are getting higher every day, so the impressions now are higher than they were last year. Does anybody know if there is a known problem? I updated my app at 1st January, too, so i am not sure, the ecpm dropped because
of my update, or because of a general problem. I didnt change much in the update, i just added the same ad banner to other pages in my app.
