I just finished watching "Video Sales Letter" by Ryan Diess and I'm still left wondering if these type of sales letters actually work. I'm going to put one together regardless and split test it myself but I do have my reservations.
I don't see very many people adopting this format in smaller niche markets. On ClickBank it seems it's only prevalent in the MMO and fitness niches.
I'm not arguing for or against this format but merely want to see what others have to say. Opinions are welcome but I'd much rather empirical data.
