Creating a membership site, and I have a few questions for those who are successful. It's an ESL site (specific niche) and I want to do a monthly subscription for about $40/month (first month free). I'm worried about retention rates and was wondering what you think works best. 1) When signing up, should I have a bunch of videos of various lengths that they can watch right now? 2) I was thinking of dripping a new 30 minute video once a week and an hour online live webinar once a week, but is that too much saturation? Should I only do one of those (live or taped)? or should I mix it up? Thank you.
