Facebook has launched a new social plugin for the site called the Recommendations Bar, which helps people filter and find articles based on the “likes” made by their friends. The little bar pops up from the bottom-right of the screen while you’re reading an article and reach the end of it.
Facebook announced the Recommendations bar last year during its f8 conference, and today it has officially launched it. The new plugin works the same way as the current “Like” button; when a user “likes” an article using the Recommendations Bar, the story is posted back on the user’s timeline and friends’ news feed.
“As a person reads an article, a small pop-up surfaces at the bottom of the screen highlighting recommended articles and prompting them to like the page,” writes Facebook engineer Jeffrey Spehar on the company blog.
For developers and site owners, the integration of the new plugin is pretty simple. All you need to do is copy the provided code from here, and paste it on your site. The functionality is also available as part of the Facebook for WordPress plug-in. However, it is recommended that you use Facebook’s Open Graph mark-ups on your articles for the new Facebook plugin to work correctly.
This is very much similar to the WordPress plugins, upPrev and nrelate Flyout. These plugins are used by site owners to increase, or accelerate more page views, and avoid heavy bounce rates. Many sites, including Mashable, Wetpaint, and The Mirror have replaced the current flyouts with the new Recommendations Bar. In early tests, Facebook reports that sites are seeing 3x the click through on the stories it recommends than through the Recommendations Box.
