I worked for a company doing their SEO. I ranked them #1 for "insole" etc and they went from 20 mill a year to just under 60. Amazons botZ picked up the gross and calculated that against the return/chargeback rate and quickly cloned out the product down the the color. THEN, Amazon pushed the real product/company (my client) DOWN in the Amazon SERPS. Suffocated and starved them out. If you use them and actually succeed, their bots will pick it up and deliver it to the "liquidation" team. Now eh hem, its not that people love Amazon so much, that is going to produce the world's first trillionaire, its vicious business practices. SO, I would not put it past them.
