Instead of logging in to two different social media sites to update your status, you can connect your Twitter and Facebook accounts to post on both Web sites at once. Each time you update your Twitter status, the update will show up on your Facebook profile. To link your Twitter to Facebook accounts and begin cross-posting, install the Official Twitter Application to your Facebook profile.
Log in to both your Facebook and Twitter accounts. Go to Twitter's main page. Select "Resources" from the bottom right-hand side of the page.
Click "See all widgets." Click "Facebook." Click "Facebook Application."
Click the "Install Twitter in Facebook" button. Click "Allow" to connect your Twitter account to your Facebook account.
