I can't count the number of times I've clicked through to a link expecting to find more context than the excerpt on the search page and that content isn't there. Instead I get trapped in a sea of circular SEO spam that all promises to give me the answer I originally searched for but ends up leading me nowhere except to other article summaries with content I didn't even want to read about. Where's the source? A good chunk of the remainder of the times I click through - especially on work-related stuff - it turns out the page is some kind of cribbed content from GitHub, StackOverflow and so forth, but mangled together and reskinned with different randomly-generated usernames making the "comments", so it seems like it's a different site, and you can only really tell by picking a specific sentence that appears unique and then manually searching for that same sentence on several different sites. No clear source there either. Web search is broken, and it has been for several years now.
