Yeah. It's hard for me to gauge because I have unpredictable traffic(surges and such on random days. One source sends between 50 clicks 3k clicks a day, to give you an idea). But I do know this. *one* of their "sale" campaigns is converting for me at 1:10 today.
I rarely see that anywhere else.
Also imo sales campaigns fluctuate on epc more than lead based. But maybe that's just me.
phew...10% CR? that's good. i was doing that at the beginning...but now i turned it off when it dropped to 1%
