Step #1 - Before you hit publish on your new content load up your Google Webmaster Tools account.

Step #2 - Publish the content and copy the canonical url

Step #3 - Go to "Fetch as Google" in the health section of your GWT account and fetch that url

Step #4 - press "submit to index" when you see the "success" message, you're done.
