An easy way to get people to become fans of your Facebook fan page is to have people in your organization Suggest it to their friends.
Here's how to do it:
1. Go the Fan Page (you can type the name in the search if you are not an administrator).
2. Go to the top left side of the Screen and Press Suggest to Friends.3. Once you are done with that, a list of your friends will show up and you can select friends to send the message to by clicking on their names. If your friend is already a fan you won't be able to suggest the page to them.
4. Click Send Invitations and then it will appear on the upper right side of the screen under Requests and say Page suggestion.
Get more fans
Have your fans also help your effort and get them to suggest it to their friends. Isn't that how viral marketing is supposed to work.
