I'm always wondering which technique people use... i know it's not that hard to gain more likes after you got like your first 1000, but how do you begin? What was your strategy? And what is the best strategy?

For example, i once heard someone said on a forum that you should upload videos on Facebook and not put a url from Youtube on your Facebook page, because when you upload them directly you get a "Like this Facebook page" in the top... but never tested this out if it really works So share me your strategy!
