This may be obvious, but I recently started routinely adding "-youtube" to google searches. This eliminates most pages with links to garbage YouTube-monetized videos that try to attract people looking for basic instructions on how to do simple things. Greatly improves the quality of search results.
@mattblaze Just checked and "-amazon -youtube" helps a ton when searching for product reviews.
@mathew Yes, the nice thing about that (rather that using "-site:amazon.com") is that it excludes not just amazon reviews, but reviews with affiliate links to amazon.
