I was doing 1:250ish with popunders, then it went south to about 1:6000 within a few months, same traffic, different surfers, I changed nothing on my end.....
Reminds me of when a partner of mine in Florida, a very short distance from Nasty Dollars HQ was pissed because his ratios dropped like mine too. He phoned them, accused them of shaving, threatened to visit them, freaked out on them, and mysteriously his conversions went up significantly, shortly after that call.
Coincidence? I think not!
I made loads of cash off of them for awhile (more then Andy Dunn was), but won't deal with them anymore. Too crooked. Too greedy.
