FB Page Fans Only
The Joomla extension "Facebook Page Fans Only" gives you the capability to create content for page fans only, thus offering an extra motivation for someone to become fan of your facebook page. This is achieved by feeding a page tab with content directly from any article of your Joomla site, where you have marked areas that are visible to page fans only. All the other visitors will see in these areas another message(s) that you have specified, similar to "this content is available to page fans only. Click on the like button to view the exclusive content".
One of the exciting features of this application is that you can achieve the same result even if the visitor is visiting your website directly, i.e. outside the Facebook environment.
Facebook Pages is a very valuable feature that allows businesses, artists, athletes, celebrities, etc regardless of their size to have their "social home" on the web. The success of a page can be counted by how many visitors it has, as well as by how many people "like" it. The number of people that "like" a page is very crucial, because once a user has clicked on the Like button, he becomes a fan and all the new content that is published on that page will appear automatically on his facebook news feed.
