Strengths - a MASSIVE affiliate network, a very solid system from both vendor and merchant sides (some may disagree, but I think it is very simple, perhaps a little rigid but that also makes it no nonsense). Weaknesses - not the most technically innovative platform, imo it could be enhanced with a full shopping cart feature rather than just buy buttons... but most don't really mind about this, especially if you just have a 1 page sales letter.
Strengths - Potential to make a great stream of income Weakness - Need to work hard in order to achieve this (O wait, this goes for everything in life. Oops)
strengths - Perfect for newbies. weakness - Internet is becoming filled with crappy affiliate sites that claim to give magical solutions quickly through ebooks.Main reason for this phenomenon is CLICKBANK [Especially generous 75% commission ]. Sometimes I feel really funny about clickbank affiliates.They are making false stories and fake review sites in order to get that 75% commission.Nobody care about the poor customers.Only very few people really know the exact contents of the ebooks they are promoting.I was also one among them but now very selective and really know about what I am promoting. I think new FTC rules are going to affect clickbank(both vendors and affiliates).
Strenghts : All of the above. Weaknesses: Like nukvn said there are ton of garbage products and you must be able to sift through them in order to be comfortable promoting the right product. Also a weakness to me is that they do not offer paypal payments.
