the biggest tip to growing is making videos that are searchable, clickable and shareable if you can do that you'll be golden, first step is searchable that means you need to be uploading relevant stuff tthat people will search and that isnt over saturated like call of duty/minecraft, most of my growth is from playing indie games for example, second step clickable this means good titles and thumbnails which well im not the best at but i find that of coarse boobs always work XD (don't just throw boobs all over your thumbnails im just joking,sorta, i mean seriously if you saw my most popular videos you'd understand why i say that) , finally shareable means what it means the video has to have something about it that makes people want to share it with their friends, now i don't claim to be amazing at any of those steps myself but I do understand that's what makes a channel succeed.
