I highly recommend blocking amazon from your searches. Even if you can't go full "zero amazon" for some annoying practical reason. It's really eyeopening how much of the commercial web they can seem to dominate. I also block pinterest. (pinterest makes it so hard to find the source of images, it's like a virus.) I consider excluding both essential.
Further, if you are going zero amazon it removes the temptation to go back. It just doesn't exist for me. I find another way.
