The first thing I suggest is to do when searching is to not opt for "all results" but 'verbatim.' Unless you choose 'verbatim' Google will try to market something to you, whether goods or opinions and you will receive search results that are largely irrelevant.
How to get 'verbatim' search results:
When you search for anything, you will see tabs with categories (images, videos, news, etc.). To the right of the tabs, you will see two more options: All Filters and Tools. Click on Tools and choose 'verbatim.' Your search results will reflect more precisely what you are looking for.
All results is the default setting, so you need to go through this rigamarole choosing verbatim every single time you want to search more efficiently.
I'm sure you all have looked for something very specific on Amazon only to be bombarded with results showing not exactly what you were looking for but something in a different color, different size, etc. They don't care what you buy. They'll throw everything at you in the hope you'll find anything.
