Mostly are based US. Am growing fan pages and doing some CPA. but is there other method to monetize this? Am doing right away. -Adsense -little CPA -Fan pages -Groups. Any other method? Or just scaling this? Because, after some accounts reach 5k friends maybe is nothing more to do. Or little work so.
Looks like you have several basis covered. Consider YouTube. You may be able to get some people from YouTube to your fan page and if you have a website that's even better. Blogging AKA content marketing is another source. Good Luck, Dan
Why don't you delete you older friends and add some new friends in your facebook. You can also create a group and add as many people as you want in your group, there is no 5K limit in the groups. You can add all your facebook friends in the group and all your friends can add their friends also and it goes on...
