Facebook Tip – How to Add Your Blog to Your Facebook Profile
The first and easiest way to post your blog on Facebook is to manually share your blog posts as status updates. This is by far the easiest and most direct way to promote your blog for free and share your content with your Facebook friends.
Log in to your Facebook account and go to the Create Post section at the top of the page.
Type something about the blog post you're sharing, then paste the URL into the post directly below your text. After you paste the link, a preview of the blog post should appear below the text box.
