1) Make business personal
People primarily use Facebook to share personal information with friends. The more you showcase the human element of your business, your products and your people, the stronger of an effect it will have on everyone who views it.
2) Update your Facebook page frequently
Facebook is geared to highlight new information and recent changes. The more often you add new content, the more often people will come back to your Facebook Page. You can also send Updates to your fans to announce in-store events, special promotions, new products, concerts, screenings or other news.
3) Harness the power of News Feed
The News Feed on users’ home pages tells them what their friends are doing.
When users become your fans, News Feed tells their friends and invites them to become fans as well. In turn, this can lead to the friends of their friends finding out about your business through their News Feeds, and so on in a virtuous cycle.
(News Feed is the key to spreading your message virally on Facebook.)
4) Choose the applications that are best for your business
Facebook and its outside developers have built thousands of free applications for businesses, bands, and every type of organization. Your Facebook page comes with the basics pre-installed, but you can easily add other applications that are right for your business. For instance, a restaurant may choose to add an application for online ordering or reservations, while a film may add a cinema locator so the user can find the nearest screening without ever leaving Facebook.
The more useful your applications are to your customers, the faster your fan base will grow.
