Do free trial programs convert better than non free trials for you?
 

Do you make more money from free trial signups or just better conversions?

Yes & no - it's easier to get traffic to the free tirals because you are promoting them as free, but that does make them convert at a higher ratio.

I seldom promote free trials they come and go too fast for me. I prefer full signups or full recurring.

ARS' free trials did convert well for me, I've had no luck with any other programs though.
