Anecdotally, I find that web search has been doing a much worse job of recognizing my query and presenting an SO result - which is why I personally use it less. Blogspam created from scraping SO has been completely pwning top results in Google and DDG(bing) and it’s really disheartening.

See for example “geeksforgeeks” and similar sites, which I find to be a poor and overly verbose resource, which now dominates the top position
