Look up tactics depending on game. Assuming you are playing call of duty or some military game. Become better player, more known. Try going through game, without dying. Always crunch and shoot and make sure you can't get hit from multiple directions. Things like that.
Are you talking about on YouTube? The best advise I can give you is play games that aren't being played by others video game commentators. Want more views because I have an idea that will work. Next year there is a zelda game coming out for the wii u. It is supposed to be the BIGGEST zelda game ever. If you do a lets play of it when it comes out, I promise you, you will get A LOT of views.
