Create something everyday. It seems simple and not really advice right? Trust me it works. I don't mean create one thing and the don't for a week or two, I mean everyday. It raises your chances of being shown in the "whats new" box, and thats where you wanna be. Imvu it based solely on popularity, and tricking ppl into thinking that what they are buying is something great even if its not. For some reason being in the "Whats New" box sets off alarms in peoples heads lol.
Outside of that? Yes the metrics mean alot. But this is the first step to getting there.
