someone talk me through amazoning search engine work?

amazon's search ranks on two things, basically: does the listing contain the words someone typed, and does it sell when shown. so the order is listing first, sales second. get the main keywords into the title, the bullets, and the backend search terms field in seller central (that one is invisible to buyers so you can dump variants there). then run sponsored products on those same terms for a few weeks to buy some sales velocity, because organic position follows conversions. reviews and price mostly act on the conversion side. one person can do this fine, the mistake is usually trying to rank for a broad word instead of the three-word version of it.
