1. Social Media site promotions
2. Multiple Forum usage (YTtalk is not the only platform available but it is the best one) and no, I do not use other YouTube related forums.
Example: You have 100 friends on Facebook, post your link plus a small description such as "Please support my YouTube career by following the link to YouTube, liking and favoriting after you watch the video"
Those 100 friends have yet another 100 friends which in turn have another 100 friends... Multiply that and you will see how a small ripple in your pond can become a huge tidal wave and in return have fun watching your views go up as well as your subscriber base.
If that is not good enough for you, go eat some ham lol
