Facebook has an feature by which you can add RSS feed of your blog into Facebook. By this feature you can share the posts of your blog with your friends and display them on you profile. To add your blog feed, login to your Facebook account and click on notes in the left navigation. Once you click notes, you can see “Import a blog” in the right side under note settings.
After clicking Import a blog, you need to enter the url of RSS feeds of your blog and click start importing. Facebook will automatically update your notes whenever you write in your blog. Imported blog posts cannot be edited. After importing, you need to confirm the import.
Now all your blog posts will be available in notes and will keep updated. You can share these posts with your friends and also display them on your profile page.
