Here are some ways to grow your channel exponentially.
Constant Uploads
In order to grow a successful YouTube channel, you must be willing to upload constantly! This means to have a set schedule on when to upload, make, and record your videos. Constant uploads also spread your videos more, as there are more of them, giving you a bigger chance to get recognized!
Viewers are Important!
To grow a successful channel, you must talk to your viewers, communicate with them. If they give you criticism such as "please speak louder" don't take it wrong, but take it as they enjoy your content but want you to fix something so they can enjoy your channel more.
Record HD!
A vital part of a YouTube channel is recording in HD. Over the years, new software, and hardware have come out to make recording of games much easier. If you ever need some recording software or hardware, I will be happy to provide you with it. Send me a private message if interested!
Don't give up!
Giving up only makes you look like you can't achieve your dreams. As Eric Thomas once said "If you want to succeed as bad as you want to breathe, then you'll be successful." If you're gonna quit, don't start. If you are destined to make videos, shoot for the stars!
Special Events!
Do some giveaways to make your subscribers more aware in what is going on with your channel. This will also grow your channel exponentially as people like these sort of events!
