It's been progressively getting worse over the past few years as they've continued to "optimize" their search engine for more ad placement and sponsored content. I'd say these past few months, it's become borderline unusable for finding actual information.
This is the thing. It really has become unusable. Trying to find obscure information is insane no matter the keywords. It's always the same results and, ugh, YouTube videos. You can't find parts for older stuff easily, simple answers are gone.
Amazon is similar. Change the keywords all you like you still will get the same 'amazon choice' products and recommended alternatives for whatever you searched for lead to the same list. But i have to agree it really got worse unreasonably fast last few months.
