My Facebook page has actually brought in about 175 new fans. I try different things to keep people interested. I post sales, contests (which I throw every random once-in-a-while), photos of new items, great quotes, and a few short personal stories so it's a fun place to visit.
I also have a personal FB page which I use for contact with friends but also use it to point people to my Wild Woman Beads page whenever I have something going on there.
Finally, I have a website where I blog occasionally, and when I do, I add a link to my blog on my Wild Woman Beads FB page.
Once you get the hang of it, it's fun and doesn't take a huge amount of time to keep up, but it does draw people in and keep them interested. Definitely recommend that you browse other FB business pages to see which you like, why you like them, and add some of those elements to your own FB page.
Good luck!
