Establishing a Facebook presence for your blog should be one of the cornerstones of your social marketing strategy. It’s likely virtually all of your readers will maintain an active Facebook presence, and being able to reach them on a site they’re going to check multiple times a day is invaluable.
Bloggers often treat Facebook in the same way as Twitter: “maintaining a presence” involves setting up a plugin to auto-post your new blog posts for you and occasionally manually posting news. If you make one manual post and publish three new blog posts every week, then you’ve got yourself four new Facebook posts every week. That’s plenty, surely?
