Using TwitterFeed.com you can simply write a blog post, and the website will automatically create Facebook, Twitter and LinkedIn posts for you. They even use bit.ly links that let you track how many clicks your posts are getting.

1. Start by signing up at www.twitterfeed.com
2. Create a feed. (This may pop up by default for new users.)
3. Enter the name of this feed. Anything will do.
4. The blog URL is the RSS feed address. If you use WordPress, your URL will look like this example: http://example.com/?feed=rss2
5. Continue to Step 2. Authorize any services by clicking them in the list and logging in.
6. You’re finished! It should grab your newest post first, so check to see how it worked.
