To connect your Facebook or Twitter account, head to your 'Settings' located in the drop down menu on the top right corner of the page when signed in. From here, go to the 'Connected Accounts' tab and connect your Twitter handle or Facebook profile. You can add as many accounts as you’d like.*
Connecting your Twitter handle and Facebook profile to bitly allows you to easily share your bitly links to your social accounts. You'll also be able to see a rich collection of links in the ‘your network’ view from the people that matter the most to you. This is where shortlinks shared via bitly by the people you follow and are friends with will surface.
* With a basic bitly account you can only connect personal Facebook accounts, not fan or brand pages. You can share to your Facebook brand and fan pages with Bitly Enterprise.
