My RPM has been averaged almost the same amount the entire day (within about 5 or 10 cents). Many times I have checked and it has been much higher, then I have checked 10 minutes later and it has been back to normal again. How can this be statistically even possible to believe? Especially considering the different sites, countries, time zones etc. I am also seeming likely to be about 35% down on Dec 2013.
So I login this morning hoping perhaps there was a click dump overnight, but even worse - kind of expected. I see the BIG Earnings Warning Indicator telling me my earnings yesterday were 86% below forecast and that I am encouraged to investigate further. "Yes please. May I speak with the head of AdSense so I can find out what the heck has changed/is wrong with YOUR system".
Oh and already today earnings are 4x all of yesterday. Sure Google it's MY site that has the problem. That's just classic salt in wounds to get that earnings warning message.
2013 was my worst-ever year, January 2014 so far is 42.67% of January 2013, it all went downhill after 28th January 2013 with Google's image theft and has simply continued to get worse and worse.
January 2013 is 72.38% of December 2013, whatever they've managed to do they've fubard it beyond all belief.
During January I have seen sites that used to get low, but steady, earnings, not get clicks for days and days on end, the worst was for two whole weeks. Those sites' traffic sources have not changed yet AdSense earnings have collapsed...I'll be deciding tomorrow which sites will have AdSense removed since I'm not leaving their ads on for pennies.
