Free site Converstion rates

[Shade]

Whats a realisitic conversion rate to shoot for if your new and if you've been doing this for a month or two? I'm just trying to get a rough estimate on what a free site submiter should be looking for in a sponsers as far as conversion rates go, and though GGandJ's stats are a bit old, i also know that there listings are a bit differnt which i'm sure has to effect the traffic, so i wasn't really sure if those where reliable.

Thanks in advance
