Get a sexy display pic, not one of pamela anderson, possibly a picture that looks from a person from myspace and isn't too edited out but looks sexy and hot and reasonable enough so other people won't say "is that you in the display?" get a nice sexy teeny one. Once your done, go to fred, shane dawson, and other famous channels that allow you to post comments, and post comment saying "rate my featured video 5 stars and comment for a free sub from me!" of course the featured video will be your video on the main channel your promoting, yall get tons of friend invites and subscribers, channel comments on the sexy account, allowing traffic to slowly buildup and letting your featured video getting known to its max from a bunch of dogmatic desperate people. Hope you like this idea and hope it works for you like it does to me!
