Hi Susan ...
I've found that it can be a 2-edged sword... I frequently have lost occasional sales because people can get so much free content on my
www.daytradinguniversity.com site, but it helps me differentiate and demonstrate content knowledge...
I've had people complain "you're charging for this video, but I can learn a lot of similar techniques for free in the free areas of your site" ...even if it's not accurate, it's perception that counts..
So I'm thinking of doing more blind-bullets and more teaser content copy, eg "Here's the first 3 of the Top 7 Secrets to..." type of approach..
And in my streaming free videos, eg I'll start with some terrific content, then fade to black and say "oops for the rest of it, you've got to join as a member" type of thing..
good point re sales momentum too ...
