How i monetize my facebook pages ?

I got some facebook pages which are above 100k and one is more than half million. All these pages getting enough traffic( almost 6k -7k likes and 200-300 comments). I really worked hard for getting this amount of traffic. I'm just wondering how can i earn decent amount of money from these pages. Can anybody please give me proper guidence about this ?

Thanks

Do you have an own blog? If yes then use that traffic to your blog and build it with more good real traffic. And if you have Adsense account then gain some amount with the use of your organic traffic.Or choose your affiliate product and promote it by the help of your FB pages.
