I find that there is often a problem of quality in products advertised.
It may be products floating in Amazon searches because of fake reviews, sites with great SEO, and most ads online really.. none of those correlate to quality of product.
Then entire point was to make finding things easy, but I find that advertising just makes that harder.
In September I was looking for a Volleyball club in Paris for people in their 30s, as I wanted a fixed team with whom I'd share interests. My searches failed me horribly. Google and Duckduckgo mostly fed me news articles, competition stuff and some big club websites.
Then my local mayor's office site had a totally out of date page, and did not list clubs closeby but outside its district.
Eventually I went to a local sports fair to meet up with clubs, but almost none of them offered adults teams, because that's typically a young people's sport.
I the end, I did find a place for me, by talking to people at the mayor's office, and random players at the fair.
And often when I look for an object, it takes a very long time because quality products rarely float above the rest. It's excrutiating.
So now I hate advertising, and I hate ratings. They are noise designed to mess up with human psychology.
