Where can you advertise your youtube channel everywhere?

I don't want to spam all the youtube comments. That would only bring me hate. I actually have good videos so far, except for the last one, which is the newest. (don't have a screen recording for my laptop yet

On all kinds of social platforms such as Instagram, Twitter, etc.

YouTube too, you don't have to spam comments, you can just write a comment sometimes.

You can also come up with something yourself.
