StumbleUpon stars and traffic

I have some questions about stumbleupon. How to get stars on my shares? I use stumbleudon for stumbling and receive 10-15 stumbles in 20 minutes, but get only 9-10 visits for a day I try someone else to discover my URL with 40 stumbles, but i has only 15 visits from this. How to get stars and more visits from SU. Before an year with 20 stumbles I receive about 300+ visits...

You need to get more stumbles. You also need reviews. Sometimes it's better to get down vote with review instead of vote up. Before a year SU was just another social bookmark site. Now it's one of the biggest site of that kind. If you have more questions feel free to aks.
