I have had two web design sites for a while each offering their own services (one is for basic and less costly sites while the other is professional web design). I haven't done much to market them admittedly, and think an affiliate program would benefit me. I don't have too much technical knowledge, but would like to know what the best option would be for this business model. I am trying to pay a percentage of each sale, and would like to know what my best options are if I don't have too much to spend on the tracking software. If it helps at all, my sites are wordpress based. Thanks in advance!
