I just gave up on Amazon Spain about 2 years ago already. It's just completely impossible to filter and rank stuff properly, just loads of crap you don't want. I heard it's worse in Amazon US.
What I don't get about this companies (because this seems a problem shared between google, YT and Amazon) is when they optimize for clicks or whatever their KPI, what are they thinking is the outcome in the mid term?
I mean, IDK around you, but I'm the prosumer regular folks ask for recommendations. They may be safe for the time being but of course I'm going to contribute for their competitors getting klout.
I don't have an alternative for YT, but people watches me using DDG and whe they ask for recommendations for buying stuff I don't even bother with Amazon.
I'm not the type who pushes his decisions onto others, but I already got asked why I don't use google and amazon.
