I agree with webcentric completely.
Everything (for me) has been turned upside down.
It was simply my turn for decimation by rotational rollout.
It involves being served 3rd tier, totally untargeted ads. They need to be served to someone, right? Well now, its me.
I have always played the game as a squeeky clean, white hat.
May 2014 will be the worst month of all time.
After 3 days, I am convinced that this statement will be true.
I have made Google over $1,000,000 (over $600,000 for me.) So I can hardly be mad at them. I was wise, and saved a pile, knowing full well the tenuousness of the relationship. (Thanks Uncle Sam, for the SEP IRA). I have always wondered when crunch time would come, for me - the point at which Google profits must continue rising, beyond any other considerations.
I believe the party is over (for me). Lucky to get $30/ day, now (down from $650/ day). The one stat I can reveal is earnings, according to AdSense TOS.
I have a new theory now, but I need a little more evidence, because it is pretty radical. It is similar to a theoretical Google update from years ago.
I have a support message into AdSense support.
When I see their response on Monday or Tuesday, I will know more, no matter how they respond. If I receive a boilerplate response, then my theory will gain great credence (to me).
It has been a grand experience, and lots of fun. But I suspect that there will be little that I can do about my demotion. Except continue saving and analyzing data. And find other ways to spend my time, that will result in new income. Unfortunately, AdSense STILL has no viable alternative. I know, I've tried them. They are all inferior (and not just marginally) to AdSense, in one way, or many ways.
At least I won't be seeing those disingenuous upside down red triangles saying "Your earnings on May 1 were 55% below our forecast". As if it were something that I was doing wrong, when they know full well that it is was THEIR actions that have caused my reduced earnings.
"We encourage you to investigate further to identify any potential issues with your site or traffic."
Hey AdSense, how about YOU do that? And then, give me the answer. I will still be putty in your hands, if you just tell me why. Not going to happen.
Walks away humming "Zipitty do-dah, zippity yeah, my, my, my, its a wonderful day" ...
