Personally, when I know that a certain topic is of high value to advertisers, I don't even bother googling anymore, and try to find someone qualified instead. For example, I recently was trying to look up theory behind working out, how differenr muscles work, how nutrition works and all that - but there're so many people who're trying to sell their courses, apps, books and stuff, that I have no idea how to go around looking for unbiased and at least semi-scientific source of information.
Edit: I would be thankful for pointers as to why this comment was downvoted, so I can increase quality of my content in the future.
