Its in the top 10 on the networks I'm on. I can only assume the floggers are the reason why.
It seems like it has become just as competitive as Acai, already.
^^^^^^^^^^
I was in it full force about a month and a half ago doing really well. Some keywords only had 3-4 advertisers. Now, my costs are double, 15-20 advertisers, completely different conversions. So you just have to take what works and weed out the rest = competitive profitability.
This stuff is tanking for me too. Barely worth the ad spend for me at the moment.
Fun while it lasted...
