Wednesday, March 21, 2007 site1 519 11 2.12% $0.54 $0.28 Thursday, March 22, 2007 site1 1,144 33 2.88% $2.66 $3.05 Now putting aside the number of impressions and the conversion rate, the eCPM is insanely different for the same site. I did not change the ads nor the traffic, nothing. Is it normal for the eCPM to fluctuate like this? How do you keep it high then? Thanks
