If I search for X I’d vastly prefer a few simple options that aren’t counterfeit or junk vs here’s 150 variants of your thing, most of which are junk but hey look at the size of our selection!
I had some interesting insights (vendors want to be unique, but need to keep products visible in search, so they typically use a common transformation within their own listings to satisfy both properties), but left before implementation rolled out. Based on current search results, either they failed or the project was abandoned.
I’m shocked at how some categories just contain junk from random brands with unpronounceable names. Want a music player by Sony or even RCA? Those brands have left that market completely for B2B products or are a licensed name on top of some garbage. Now you can get a Zaqe, Picxiul, Lwyinp, Globluum, or Swofy!
IE folks will take a 4 pack of something that sells for $20 and sell each bottle individually for $10 each.
For heavy things the shipping ding is bigger, but they also usually cost at least $30. No one bothers to sell $5 items like 50lb bags of basic sand on amazon.
