When I launched http://bugmuncher.com http://bugmuncher.com I offered a 7 day free trial. Not too sure why, I think with it being a very MVP launch I wanted to find out if people would be willing to pay as soon as possible. Later I A-B tested 7 days against 30 days, and found 30 days did perform better, but not actually by that much. The 7 day free trail had a 9.95% conversion rate, where as 30 day had an 11% conversion rate. I personally was expecting 30 days to do much better, but after seeing these results I suspect the length of the trail isn't very important to users, they just want to know that they can try before they buy. I may try A-B testing 45 days (and maybe 60 days) if I get bored and can't think of anything else to test.
