That's been the most annoying part of search for a while now. Most searches result in hyper commercialised results, with SEO heavy sites winning out, and of course SEO heavy sites are going to be sites selling you stuff.

If you're searching for a real human's thoughts on a particular mountain bike for one example, it will be nothing but product pages. Add in the word Reviews and you get the productized review sites. Even searching for "Best trails in {my area}" gives me an ecommerce site's blog laden with product links and not-so-subtle sells.

Want to read a discussion about a book? Google will only show you product pages with review sections on the first page, on the next page the search results have already devolved into unrelated nonsense or spin sites.

It's hard to find the humans on the internet through all the commercial pages. I can't blame Google entirely of course, they are helped by the SEO industry's incessant bombardment in the 2010ish era that filled the web with so much pointless crap, and the ongoing efforts of e-commerce stores with deep pockets to be the only heard voice for particular subjects.
