Kush,
I can't say for sure what you might have a problem with, but I think new sites seem to do better RIGHT WHEN THEY come out.
I did extremely well with TrannyHouse and some of their other new sites when they first came out (less than 1:30). I think that might be some of it - as cheerchicks is new, but I don't know - it seems that was to me - after a while - things start to average out (at least for me).
I know this isn't a great analogy, but I used to sell tons of pokemon cards - when I new set came out - sales skyrocketed - and then would settle down after a couple weeks.
What I have learned is any new sites from ARS, TopBucks, CyberErotica, and anyone else you trust - don't wait to see how new sites are doing for other people - just start promoting them right away. Surfers have never seen them before.
It isn't just topbucks I have seen this with, but sites like
IndiaExposed (ARS)
TeenPanties(ARS)
EnticingTeens (CyberErotica)
Just my

If your sponsor comes out with a new site - and you like the tour - don't wait for other to show results - you will miss out on the action.
