My RPM (Revenue Per Thousand views) on AdSense started to drop for past couple weeks, and now its 72,6% less than 28 days ago.
Only things that I can think of that I did in past 28 days:
I moved one of the pages to httpS (but my other site has SSL enabled for months and I never had that problem) and also i think RPM should not be affected by that, only the actual income.
And then I added one more ad to one of sites. All of the sites have maximum of 1 ad per page (as I hate when people use tons of ads). and I noticed the drops of RPM right after I enabled it. Also, like 25-50% of the time, it just shows blank space (so AdSense has no ads for me), but that too should not affect RPM.
Does somebody have any idea? All google tips are at 5 or at least 4 out of 5 points/dots, so there is no problem either.
If the drop was like 20%, I would be somewhat ok, but 72,6% drop and still dropping? For past 28 days I had 246 275 views of my pages.
Is there some fix I can do, is it some google bug or thats just how google works? Will it get back up? As I have to pay for servers, and even before drop it was bad (thats why I had to ad that one more ad to site), now its just terrible and I am getting less money with that new ad, than i was getting without it.
