Interesting. I think I typically must have specific things I'm looking for. Like for example, I probably wouldn't look up "pet sweaters", but WOULD look up something like "canada pooch dog sweater". Which, takes me past all the seo-ad-targeted junk.
And now, the more I think about it, I'm typically using amazon's search for zeroing on something specific. I wouldn't even do "car charger for phone", but would do something like "Anker USB-C Charger for Pixel 6a".
And likely, most items I'm going for I'd be referred to from a site, like America's Test Kitchen or something.
In short, I guess I don't "search for discoverability" on Amazon at all, and that's how I stay out of their optimized mess.
EDIT: I also don't really purchase things that aren't independently reviewed elsewhere, like using ATK for some kitchen items, etc...
Look up "pet sweaters". Resulting brands listed in order: Dxhycc, Fitwarm, ANIAC, Jecikelon, Queenmore.
"Audio streamer": WiiM, Andover, iFi, Arylic, Douk, ACEMAX.
"USB cable": Jelly tang, AINOPE, Ruaeoda, etguuds.
I could go on, but you get the idea.
