I've tried sending both MSN and Facebook traffic to this squeeze, with abyssmal conversion rates... I haven't broken 20% optin rate. Here's the squeeze:
The #1 Workout Routines Blog for Men (and Women Too :-)
I'm sure I could tweak my squeeze page, and in fact I have 2 other versions that I'm split testing against each other, but I'm starting to think that PPC traffic is useless for building a list.
What do you think?
