You NEED HR views in order to rank your video or how else do you think youtube will see it's worth something.
The most important thing is the "onpage" stuff. I won't go into detail cause it's too complicated.
Next thing is views, likes and comments (engagement). Most people on these forums are "SEO's" we want to rank everything.
But since you are a newbie I am sure you think youtube is all about making a good video and if people like it they will share it and that's how it gets many views while in reality it's all about ranking. On youtube just like on google.
