The Facebook plugin for WordPress adds Facebook social plugins to your WordPress site. Associate your WordPress site with a free Facebook application identifier to enable advanced features such as automatically sharing new posts to an author's Facebook Timeline or your site's Facebook Page. This plugin is developed by Facebook with extra support for popular plugins and themes, custom post types, and custom post statuses.
- Open Graph protocol markup optimizes your content for social sharing and rich story previews on Facebook, Twitter, Google+, Mixi, and more. Display large images, link to author pages, and improve story distribution through social news feeds.
- Facebook Insights support for Facebook accounts associated with a Facebook application. Track rich audience data powered by Facebook profiles (age, location, language) and see how your content is shared on Facebook.
- Add Like, send, and follow buttons to every post to help your site's readers share content with friends or stay connected to future content shared by your site and its authors on Facebook.
- Embed Facebook Posts by pasting a URL into your post composer, creating a shortcode, or calling a function from your theme.
- Enable the Facebook Comments Box social plugin to encourage new comments from logged-in Facebook users and his or her Facebook friends.

Advanced features include moderation, blacklisted words, automatic grammar correction, and login support for AOL, Microsoft, and Yahoo! accounts.
