Posting to Facebook, LinkedIn, Twitter and other social media sites is a great way to interact with your customers. You'll wind up spending a lot of time working on content to write up and add to these sites. But which should you be posting to? The ideal thing to do is post to several so you can target more people, regardless of which site they are using. The problem is, posting two or more times takes time, and who has extra time? One great way to save some time is to link up your Facebook and Twitter accounts so you post once, and they share the content with each other. This used to be a real pain to do. There were a variety of different apps from different people that claimed to accomplish this with varying success. One huge problem was that the API's for these sites are always changing. One wrong move and the app would suddenly stop working. The other issue was that these apps were pretty tricky to set up.
Thankfully, Facebook has provided its own solution, and since they control their own API's, you can bet it will be more stable. It's also very easy to install and configure. Here's a quick walkthrough.
First, visit the setup page:
http://www.facebook.com/twitter
You'll be asked to link your profile. Click the green button. You'll then be asked to authorize an app.
This creates an application inside twitter which allows the posting. When you go to your settings page in twitter, then to the applications tab, you can adjust access if you like.
Then you will be prompted to configure the app. It's very simple. Choose what kinds of items you want to be shared. If you are the admin for any pages, they will appear here too and you can set the posts from those pages to be shared too. Choose whatever makes sense in your situation.
To adjust these settings later, just go back to the same page and you can adjust everything.
