Google search results have been gradually getting worse for me as well.
OTOH, if it's anything that has been SEO'd, I find google has gotten really bad. Last week I tried to google for what frying pan to buy, and everything I saw was a un-trustworthy ad.
Incidentally, it's the same for python: you google some very common thing like how to sort a list, the first few links are spam (but the docs are still high in the list usually). You google something obscure and usually get the relevant stack overflow first.
