Do You Know The Average Conversion For A Sales Page In The Weight Loss Niche?

I offer two of them, then.

(i) For a $97 e-book weight-loss product on ClickBank with SEO traffic sent directly to an affiliate-link to the product's hyped-up sales page, which was itself written for $97 by someone pretending to be a copywriter, has screaming bright red headlines and announces "only 19 copies remaining" and explains that "the price is going up tomorrow", and has a couple of exit pop-ups giving progressive discounts just for good measure as well, the conversion rate will be a big, round, fat 0.00000% and will probably stay that way for ever, without even the occasional "random sale" you might expect by chance alone, out of enough traffic;

(ii) For a $47 e-book weight-loss product on ClickBank with syndicated article-generated, non-SEO, ezine-subscribed traffic sent initially to the opt-in page (not a squeeze page) of a content-rich website, given a free report, and then treated to a slow-moving, consistent, continuity-based autoresponder email series establishing credibility, trust and respect, and then sent to the sales page which was written by a good, successful copywriter and has had many components split-tested, the conversion-rate could easily be as high as 20% (and in a lot of niches it could be even higher than this - but this thread's about weight-loss, which overall, understandably, has some of the lowest conversion-rates you can find).

I'm not in this niche any more, myself, I admit, and can therefore offer no better - but I think those are two realistic enough examples.
