The top-ranking HTML editor on Google is an SEO scam

Same story for various Wordpress plugins and widgety things that live in site footers.

Google has turned into a cesspool. Half the time I find myself having to do ridiculous search contortions to get somewhat useful results - appending site: .edu or .gov to search strings, searching by time periods to eliminate new "articles" that have been SEOed to the hilt, or taking out yelp and other chronic abusers that hijack local business results.

The reason for that is actually rational: when Amit Singhal was in charge the search rules were written by hand. Once he was fired, the Search Quality team switched to machine learning. The ML was better in many ways: it produced higher quality results with a lot less effort. It just had one possibly fatal flaw: if some result was wrong there was no recourse. And that's what you are observing now: search quality is good or excellent most of the time while sometimes it's very bad and G can't fix it.
