Twitterfeed is a way of making all your efforts count double or triple. Essentially, each time you publish a blog entry, it automatically also gets posted to your Facebook page and is tweeted too. Furthermore the tweet automatically gives you a short url linking to the full blog.
Potentially (since we don't know exactly how Google works and it changes) this means that Google will find three links for the effort of one.
It only takes five minutes to register your email address with Twitterfeed, then to tell it the blog that the information is coming from, then to give it your Facebook page and your Twitter account to post too.
I know you'll be pleased about that!
