Unfortunately I only found 1 MFA & it seems as if both my sites are affected (they are related niches). This is the least amount I have made per day in 3 years & now today's eCPM is half of what it was yesterday! YIKES!
One-day's statistics never really concern me. When it continues for a while is when I really start digging for explanations. eCPM is half...what about traffic, clicks, etc?
All your answers are here: http://adsense.blogspot.com/2009/03/updates-on-account-access-and-reporting.html I suggest you dig the official source once in a while...
Ummm... I have looked @ the original source (about 6 hours ago) and no all the answers are not there. That particular problem is not relevant to my situation since this the drop in earnings started about 5 days ago. My site had reached the point where it went from about 10 cents per click to not even 1 cent a click. Traffic is the same - CTR is 3% higher. Very strange! Is it possible someone is purposely clicking on my ads? How would I know? I have pulled the ads for now....
