Youtube Contests, what and what NOT to do!

On Youtube there is alot of contests. There is contests on many things, they have contests where they give away Make-up, purses, gift cards, i-pods, and so many other things. How do you enter theese contests? What I usually do is go on Youtube and type in "Contest." Contests will pop up, but make sure they are still happening, you dont want to get excited and enter a contest that has a good prize, and it was over 3 months ago.Check the date! You want to pick a ghood contest to, but you really could enter any contest. Check to see how many viewers/ enteres the contest video has. You can enter the popular ones, but if yuo see one that dosent necessarily have a good prize, enter it anyways, its FREE, because if its not that good of a prize chances are that not that many people have entered that contest and you may have a  better chance of winning, Lastly always be carefull not to give your address to a randome person so they can send you your prize, check, make sure this person is safe. use theese tips, and you should be able to survive sucessfullyon the internet, or a Youtube contest.
