Funny and entertaining videos are more likely to go viral. Try to be as edgy and humorous as possible...you will need to push it hard to other social networking sites and give people a reason to share your video...it can be a contest, an incentive anything, like 'RT or comment or subscribe and you will get that'. Don't forget Youtube ranking factors: rating, views, comments. An active and challenging comments area is important...communicating between your Youtube accounts or getting help from friends and get more coments can be a solution
