I've pretty much entirely redone the salesletter for my diet affiliate product and thus far conversions have increased - although I'm still looking for further improvement of course. This is the new salesletter. I'm just looking for some helpful critiques on how to improve it further or what jumps out as being wrong to you. I've JUST (like 5 minutes ago) added a very prominent opt-in box that I'm hopeful will greatly improve conversions - although I still need to set up my whole autoresponder series. And no - I will never put my own affiliate link to my product in my autoresponder! It's there to improve conversions of the product for me and for my affiliates. Affiliate Tools.
