I have been telling my mum the same thing and she don't listen. Googling for reviews used to work very well to like 3-10 years ago. I don't speak English nativly, and I suspect that it worked better in my native tongue for way longer then English. It is like it takes time for it to sink in for people, when they are trusting a process or institution.
I wanted to buy a ultra-sonic cleaner for my garage/workshop. I need it to clean out parts. I searched for reviews on Youtube, and I noticed that the big "ultrasonic cleaner on Amazon" manufacturer Vev[*123]or seem to more or less have donated a cleaner to about every workshop genre Youtuber in the last 1 to 3 years. Or paid them to shill. Dunno.
I mean I was flabbergasted to the extent of the manipulation. I didn't think it was this bad. And I did end up buying their cleaner ...
*123 I just don't wanted to SEO help them.
