Are you asking if the clickbank code is a good product? If so, then my opinion is not really. I purchased it. While it starts out strong with good info it dies out rapidly. I think the guy got lazy. It really depends on how much experience you have. If you are new I would not recommend it at all. The program tells you all the right stuff and is helpful in places but when it comes to details you are left on your own. He just tells you to go build your website , landing pages, blog and articles. He doesn't show you how to build quality landing pages, websites or blogs. You will be totally lost if you are new. I have built all the above but still can't build quality that converts. That is what he leads you to belive in his pitch but it is not the case. If you are adept at doing these things then it is a good product because he gives you a good formula to pick winning products with a spread sheet.
What kind of course are you interested in? PPC, CPA, etc.? There are really hundreds of different courses but most all the information can be found in forums right here, but if you're looking for something specific let us know.
I just got the Commission Blueprint a few days ago, and I like it. It's geared towards Adwords and Clickbank. It's helped me quite a bit, so I'd reccomend it. I've heard that the Clickbank code is just a rehash of the material in commission blueprint and at a lower quality.
The clickbank code is a great ebook if you're looking to jump into affiliate marketing. Some methods explained in the CB Code aren't avaialble anywhere else. Apart from that it contains endless methods to generate traffic to your landing pages via PPC mainly but not only.. I have purchased both commission blueprint and CB code.. however I found The CB code more valuable.
