Does it convert higher when
 

you send visitors to join page rather than home page after they click on a picture??? TO me it converts higher when u send to join page.. but my affiliates dont want me doing that.. why?

It depends on what kind of visitors they have.
I send visitors to top pages but conversion rates are less than 100.

you won't know if you don't test it...

home page is better

I agree with you man, as a practice shows, mostly home page is better

The visitor should know on what site he will be directed. Join page it's good, if the main goal is to get signup, but if you need more sales from this user, I think the best way is to move them to the main home page

Yeah, but it depends... mostly on offer and your traffic. It's hard to predict, the best way is testing and testing :)

Your noticing traffic is only making it to homepage leaving after one click and wondering whether this traffic will convert better if you send them to the sign up page. The answer is no if they are truly clickers they will click from sponsors homepage to their sign up page. It is about the quality of traffic they will just wonder why a sign up page is appearing.
