I honestly don't understand why people say that they don't make sales with CCBill programs. My site has always done very well in terms of generating sales and I've been using CCBill for 13 years now. I don't think you can blame the processor, the hosting company or the domain registrant. People always want to shift the blame when they're not making sales.
I think it depends on the program itself, as well as the type of content bring promoted. Another big factor is updating the site on time and on a regular basis. I always update my site very regularly with new models and content, which is good because it gives the customer a reason to come back to log in. I have customers that have been members for YEARS ....and the sales continue to flow in just about every other hour during the day and evening hours. These are new sales and re-bills.
I am just stating my own personal experiences and views on the matter. But yeah, I've just never understood why people say that because that's clearly not the case with my program. I think you are cutting yourself short by lumping ALL programs together that use CCBill just because a few others didn't do so well.
