How do you promote a fan page on facebook?

I always see on comments little links that you can click and it takes you to the fan page and you can click become a fan--and idk if i just copy the link at the top if it will take it to the edit page. So do you know where the link is? and p.s. it called Your Lady Gaga's Little Monster so become a fan of it

U have to pay for the advertisements, but when you go into the page, it will have a thing on the side saying that you can advertise it
