I had my worst day when it comes to eCPM yesterday. Looking a little tiny bit better today for now, but I guess there is still time for it to hit the floor
I am currently studying my adsense account, and I found out that the eCPM is really different than those before, but most of the clicks on my sites earn only a little cents just like before, except the one I posted earlier.
Google Surely is working now to retain the publishers. Recent changes are : AdSense now varies the number of text ads that appear in a given ad unit. In cases where we determine that increasing the size of the most relevant ads will improve performance, we'll drop the lowest-performing ad or ads and expand the remaining ones to fill the entire unit.
