Right now, the algorithms that get you more visibility on youtube (and the internet in general), is quantity over quality. That's not to say that just making a bunch of shit will work either, but don't try to put too much effort into the videos. Once you have the idea of what you're going to do, get the pace of 2-3 videos a week down, and get comfortable with it. Then you get to move onto the next step of self promotion. and I highly recommend you do it in this order, because unless you're going to be able to put out 2-3 videos a week for a long, long time, there isn't much point in promoting your channel, especially if you're going to pump any money into it.
