How to you promote your site on it ? You upload some vids over time or also make alot of comments on other vids ?

I make some comments but also tell alot of people online in the game I make the vids of they should check out (vid name) most of the time they check it out. And now one of my vids as already 240 views. And subscribers are also coming in faster then before I started making vids. Its all about promotion the vid you just made on youtube and on other places. Once you builded up some subscribers you won't need to promote it anymore.
