My youtube channel doesn't get noticed.?

You seem like you only have one problem(Advertising yourself). You need to tell your subscribers to tell others about your channel. You need to post your videos or share them on social media.

This will definitely give you more followers.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
