I have a few big channels. First, if you want to grow, you're going to have to jump into different niches. Unfortunately, for most people it is very very hard to make content that they're passionate about and be able to grow with it. If you're getting into a niche like gaming then yeah, you're going to have a very hard time. Usually I just browse the front feed and look for niches that are up and coming and try to jump in quick. And second, focus on volume in the beginning and not too much on quality. When I start a new channel, I don’t obsess over making perfect videos. I just focus on making decent ones quickly. The goal is to put out enough content to attract a small group of returning viewers. You're going to have more chances on hitting the algorithm with one of them and once that core audience is there, then I start improving quality and putting more time into each video. Those loyal viewers are the ones who’ll give the next, better video its first real push. There are millions of amazing videos that never got pushed anywhere. You’ll usually have better odds by editing faster and making more content than by spending weeks polishing one video.
