Facebook: How do I keep gaining more likes i have 58k+

Basically on twitter when you have a big active following you find other pages and cross promote each other with retweets and goals.

i just bought a facebook page with 58k likes and like 6k talking about this.. what can I do to keep it gaining more fans? i gain 1-5k followers with above method on twitter but like a couple hundred off my facebooks pages posts... i don't understand the language they use in s4s groups really. if someone could help. it would be awesome! thanks

There are sharing groups in facebook.You can look for them with names l4l,s4s,sharing,likes4likes
S4s :You share them and they gonna share you back same goes for l4l or likes 4likes instead of sharing.
In s4s you need to share a pic or post without caring number of likes they can generate from it on there page duration is 30min mostly.
With l4l you'll tag there post till they get those amount of likes like 200 l4l that means you and the other person are going to exchange 200 likes on there pages.

keep promoting your facebook page. Maybe do a fake giveaway and say "First 100 people to share this post will be entered in an iphone 5 raffle"

By promoting them on Big Pages. (Though it's a paid option)
