How do I get more likes to my Facebook page?

[vidushi soni]

I have a Harry Potter page on Facebook, and I work really hard on getting likes to it. I do promo for promo, a.k.a share for share and things like these. I put up competitions. One is currently going on. I post a lot on the page and it's pretty active but I don't get like, A LOT OF LIKES SUDDENLY. My friend has a WWE page and when I had around 3K likes on my page he had, 1.5K on his. Now, I'm 4K and he's 21K or something -.-
I asked him what he does to get likes and he says he does nothing at all. Not even promos but he just gets likes because WWE is famous and Harry Potter is over and not famous anymore(I felt like punching him in the face. I love Harry Potter and it'll never be over for me.)
He says he gets 2 likes in 1 second or he's just bragging. Whatever. I really need to know how can I grow my page. Please let me know if you got any tips? Thanks.
P.s. My page is : http://www.facebook.com/YouBetterNotInsultHarryPotter
Just in case, you would like to "like it" ^.^

suggest it to your friends and ask them to suggest it also to their friends. also try to plug it to other pages that have many likes so many people can see it.
