I want other people to promote my products. Currently they are not capable of being promoted for and I want you to tell me some methods of how to prepare them. So, for instance: one product is a picture. It is a picture on demand, so if you want to have this picture (high quality printed on canvas) in a special size at home, you use this service (not mine) to create an unique picture out of my original, which I uploaded once in suffice dimensions. The issue here is, I do not know if the visitor of this service is actually going to buy. What I can see is that someone is visiting the site if I use a tracking-php-site, that means I can identify him or her by his IP address and I know, that someone bought. But I do not know, who bought. So I can not assign him or her and ultimately I can not pay out a possible affiliate.
