Post videos!
Actually, there is a little more to it than that. First and foremost, you have to decide why you want to make videos in the first place. Depending on your reasoning, there are actually many different ways you can do YouTube "right". If you are enjoying what you are doing, then really ANY way you want to do it, is fine. However, if you're looking to grab some audience, and want to retain their attention, then that's a different story. Contrary to popular belief, you will not get famous overnight just by uploading some gameplay commentary, and screaming like an idiot. Besides, that's already been done. Which by the way reminds me to tell you that originally is spawned from likeness. So, keep in mind that if you want to be original, you might need to find inspiration in others!
Make sure your content is well made! Light, sound, video quality, etc. Things like that! Go ahead and take actually take time to set up your channel before "launching" it. Nice looking banner, avatar, cheesy one-liners you'll drop/or sign offs, etc, things of that nature! Making videos and uploading them isn't hard, nearly anyone can do that. Though, to create something of great interest, that takes work. Unless you just copy others, and do things like "Challenges", "Tags", etc. Things that require no real effort. Now, as far as your videos go, keep them short, sweet, and to the point. Grab your audiences attention ASAP, and do what you can to keep it.[DOUBLEPOST=1414519002,1414518870][/DOUBLEPOST]Also, a side note for what
