>...I rank very high on the major search engines for my product
This matters not the least bit to us. We'll happily list a site without another link to its name.
>It is also in every major Human Edited Index except for the DMOZ.
This also doesn't affect our deliberations.
>I have the lowest prices ...
This typically doesn't come into consideration either.
>I also have a lot of scientific and journalistic information on my site regarding the products, their effectivenessm, and their usage.
This is good search engine bait, and perhaps good for attracting customers, but for a SHOPPING category, what counts is information for the customer, relevant to the transaction: Exactly who is selling exactly what, when, from where, how, and for how much.
Why, or to whom, are questions of deep concern to retailers and marketers, but of no interest at all to us.
