4Idiots has quite a great conversion rate. I have been using their new landing page, there's a special link to that in the affiliate section. Luckily I was all new to the weight loss niche and had some unexpected success, from private ads, ppc, article marketing and a few other traffic sources. Not sure if 4idiots does just as well lately, since there's a few other products that in the arena now. Al.
well i can always rewrite copy, i actually have a draft now which fits FBF...and the current site targets CYWT. I think the bigger challenge will be ranking the keyword(s)..wish me luck. I know its a tough niche. But i have seen some other fellows ranking #1 in Google for some GREAT keyword (like the guy who ranks for "teeth grinding" <- jealous...)....so the rest and the main success will be pure math, backlinks and some time to pass. It will certainly take some time to rank this.
