Hi everybody. I created my first membership site quite a while ago, and don't even remember any stats on it. But, the best one I've had was created some time last year and made just under $3000 in its first month.
http://www.MyListNetwork.com
- Members: About 1700 members (most are free), and practically all came from viral marketing
It's a great system, and I'm going to be updating it with more features soon after I launch my newest project.
I'd say that there are two tricks to having a successful membership site:
1) Making it viral--absolutely essential, and
2) Continuing to add value, because no matter how great it is, people have a tendency to get bored over time
3) Continue to market it yourself in addition to the viral aspect, because no matter how viral it is, it's always good for you to start more branches of viral members yourself.
I've always been pretty good at #1, but I've made mistakes on 2&3 in the past.
