I currently own two 2'000'000+ likes pages and one 3'000'000+ likes page, with great demographics (mostly US). The niche is general, not something specific. I was thinking of selling post updates on the pages (I post the client's URL on my page), $50 for one post on one 2M+ fanpage and $70 for one post on the 3M+ fanpage. Is there anything better I can use to monetize my fanpages? I could really use some ideas right now.
