With one of my BANS sites that is less than 6 months old, I usually get anywhere between 20-60 clicks a day and between 1-6 sales a day (and zero sales for a single day every few days). Good niche I guess! For this site, from 10/1/07 to 10/10/07 (today) I have 488 clicks, 2 paid leads, 34 sales, $83.76 (total commissions and leads), and a $2.12 EPC. The sales commissions are anywhere between a few cents and a few dollars. It varies GREATLY! Also, ALL ORGANIC TRAFFIC! I do not spend a dime on advertising, outside of every now and again paying someone to post links on blogs or submitting to directories... By the way, I agree with BOTH Kelvin and jonixkonios. Im not sure so I can't say for sure, but I think a "cookie cutter" bans site will never perform well in the SERPs. Although, this could be because of the owners work ethic. If they are not going to take the time to customize their stores, then how much work do you think they are actually putting into promoting the site? I also think customizing your store helps with CTR. Making your store unique will make it NOT look like an affiliate site, and visitors are more likely to click through. Even when they realize that they have been taken to ebay, they wont mind as much because your site had a GOOD feel to it. This could also create repeat visitors in a good niche.
Right now I have 0 clicks I just bought it yesterday and im working on a template for my first store. Just finished coding it to css / xhtml valid, now I just need to integrate it into the BANS script.
