Well, i see it this way - sorry for my bad explanation: I'd rather find videos, instead of getting them "thrown" at me, that's the reason why i try and let them be easier to find. People search for everything, even with multiple words. So you will still get exposure, if you do even more specific tags than you thought. Because the "common" tags, i would say is the single words. Almost every youtuber uses those, and therefore, if your vids only consist of them, guess what page your vid will end, against channels with millions of subs.
- I hope you can use just a tiny bit of this
Thanks alot! May all your viewers sub you!
