But what really bothers me is the possible negative effect that some affiliates can have on branding. I've just done a thorough web search on my product name and I'm a bit disturbed by some of the trashy websites I see promoting my product. Some are good while others totally misrepresent the product or give an unprofessional image. I think this could do real harm when prospective customers search the web for reviews or independent feedback.
I've never heard a discussion on this aspect of Clickbank and affiliate sales in general. But if you're trying to build a good brand you really need to keep tight control over your product and image.
