How to Add a Follow Button to Your Facebook Page
You have the option of adding a Follow button to your own Facebook Timeline to enable non-friends to receive your public updates in their News Feeds. Just follow these easy steps:
Open the Account menu by clicking the small down-pointing arrow in the big blue bar on top.
Select Settings from the menu that appears.
The Settings page appears. Items on the left side of this page allow you to edit different types of settings.
Select Followers on the left side of the page.
The Followers section of the Settings page appears.
Select the check box to Turn On Follow.
A series of other settings related to being followed appear:
Follower Comments: Here you can control which people can comment on your posts.
Follower Notifications: Choose which people interacting with your posts generate notifications.
Username: Set up a username so people can quickly type a URL into their browsers and go straight to your Timeline.
Twitter: If you already use Twitter to post short updates, you can automatically import them into Facebook here.
If you had previously turned off the capability for your Facebook Timeline to be found via search engines like Google or Bing, you’ll see an additional setting here called Follower Search. Checking this box turns back on your capability to be found in searches people do outside of Facebook.
