Example of the new "Yo-yo" revenue model.
Notice the daily average PPC:
$0.09
$0.12 Up
$0.84 Up (wow, we'll make some money)
$0.13 Down (oh dang it)
$0.59 Up (I see some light at the end of the tunnel)
$0.06 Way down (the pain never ends...)
my earnings is falling down
Whenever I see this thread title I can't help but think: "I've fallen and I can't get up."
