Or maybe I dont..
$913 spent and the banner which is normally 0.8% CTR on TJ on the same position did 0.15% (300x250 blind video banner) on your system resulting in 1509 clicks ... 2 sales = $60
This is pure US traffic I might add.
There's no way in hell that that banner only did 0.15% CTR - Your system aint counting correctly, that's 100% sure.
Well, hey ho.. $913 out = $60 in .. I think that'll top as my worst ad buy experience ever
