Before I detail a proven formula you should know that approx 25% of people who will join a site with the recurring option will cancel even before logging in, PEOPLE ARE SCARED OF THE WORD "RECURRING".
On that note always remember to offer a one time payment option.
Now here is a good retention formula.
Exclusive content
3 updates a week
here is how to work it
Lets say you have 5 sets, break each set down into 3 parts:
And update, monday, wed, friday
Spread the updates out so week 5 members see part 2 of the first movie update, keeping them curious while at the same time giving them many updates.
Also in my new site
www.tushyschool.com im using DRM
Many people join sites download everything and cancel and have jerk off material for the months to come, or share it with others.
With DRM only members can watch.
