down over 75% today. was on fire all week, but noticed the drop off yesterday. i'm also experimenting with some new ad placements, but will probably be going back to my old faithfuls!
I know the earning does fluctuate a lot from day to day, but I really notice that the eanring per clicks has been dropped in the recent days.
Same boat here today for me, about 56% drop in traffic/clicks for my main site (have not seen that much of a drop in months). I hope this is just a bad day and not Google doing major shifting around again. Got hammered last time that happened, went down to crap for over 8 months.
