I maintained a CTR of 8% or better for YEARS.
On April 1, my CTR immediately dropped to UNDER 4%, and has been there ever since. I made no changes of any kind.
Something REALLY BIG happened then, which has NOT been explained. I can't understand the lack of buzz on this topic. Others got blasted on March 15. I think they stagger these things, to keep the noise level down.
The bizarre thing is that my EPC doubled, and is now back to 2006 levels.
It takes a lot of faith to stay with these guys, no? Especially since you can be summarily executed at any time, with no explanation whatsoever. I am currently embarking upon a diversification binge. There is just too much uncertainty, and lack of transparency. Only an idiot would put all their eggs in one basket, in light of all these unexplained, unfathomable "adjustments".
So, you think it is the "interest-based" ads thing? As good a guess as I can think of. How can we know?
