Facebook provides facility to promote you Facebook fan page by sending invitation to your friends. You can invite people who are added in your friend list to join your page. But sending invitation to thousand of people one by one is a very difficult task. But this is very easy to do by using a Google Chrome extension. Please just follow below few steps:
Step 1-> Open Google Chrome browser on your system.
Now Google Chrome Invite All extension installation page will open. Click on +FREE button located in the right side. This button will start the installation of this extension on your browser. After completion of the installation the button +FREE will get changed into ADDED TO CHROME, means extension has installed successfully on your browser.
Step 4 -> Click on Build Audience -> Invite Friends
Step 5 -> You can see a new button named Select All before Submit button. As soon as you hit the select button all friends will get selected. Now hit on Submit button to send invitation to all selected friends. Please see below screen shot.
