So your estimated earnings in YouTube analytics, or the amount on your Adsense screen? Is this your CPM you're talking about, or your daily revenue chart went down one day to half of what it was for the previous days? It's difficult to get a clear picture from what you described.
I'm talking about my estimated earnings in analytics and guess what,
they are getting lower each day. I've already sent a mail to YT but haven't got any answer.
As I said before I've never had a copyright infringement, and everything is ok. The only different thing that happened was that I got more views in December than now, but I didn't know that estimated earning could go down AFTER they appeard on screen.
PS: I don't work with any network and used TubbeBuddy (which I unistalled fearing this was responsible, though I doesn't seem so since earnings just continue falling... )
