Yesterday had 20% more traffic than the previous day and AdSense earnings were down 40% from previous day.
On a bright note one affiliate program I'm in is coming close and on some days exceeding AdSense earnings.
Biggest drop I see is the 160x600 ad units. CTR is about half of what it used to be since the new design.
336x280 and 300x250 CTR is up but not enough to cover loss on 160x600
