These days I see mostly SEO spam articles for any topic that has even a modest amount of search traffic, commercial or not. Like if I search for how to do some random DIY home fix, or lookup information about a sort of niche topic, the front page will be 10 terribly written (likely automated) articles that all summarize the exact same points as each other. Clearly they have all copied from the same source. It's crazy how hard it has become to get Google search results from a human that put a bit of original thought into something.
