I'm 3 weeks into creating my new channel and want to share what I've learned after being quite successful. Here's what I've learned...
First, I spent hours watching several creators talk about the algorithm, what steps to take when starting out and what to do (and not to do) when you upload a new video. This is extremely important and it is why I'm where I'm at right now.
Second, I make sure I engage with comments all I can. My contribution is a tiny bit of the total comment numbers, but they help YouTube know you're serious.
Third, keep on topic. YouTube is trying to learn what you are all about. If you change topics every video, they won't know who to push it to.
Fourth, don't obsess over analytics. This one is difficult because when they start pushing your video, it's super cool to watch the graph. Anyway... the analytics you MUST watch is your CTR and retention. Look at the retention graph as SOON as it's available. It will show you when viewers drop off. When you see the drop off, look at what happened in the video. In the future, don't do what that thing is. In my case, I saw a lot of drop offs when I asked for subs. Now, I just show the animation for it, but I don't stop running my mouth on the video topic. I keep on subject.
Fifth, don't expect overnight success. Growth will come if you keep going. Don't give up!
If anybody has any further questions, please ask. I'm new to Reddit so forgive me if I don't answer immediately. I have no idea how the notifications work.
