Now there is a wordpress plugin to easily allow WordPress publishers to easily integrate their site with Facebook, enabling them to enjoy powerful features, such as social publishing and mentions.
The plugin was built by Facebook engineers in collaboration with open source partners, and makes it simple for anyone to make their WordPress site more social – no coding required. The plugin will also work on mobile and support internationalization.
Social Publishing and Mentions
When a Post or Page is published, it can be distributed to Facebook in a number of ways.
The author can choose to mention Facebook friends or pages. They can also specify a message that will be posted with the content.
Once published, the content of the post of page will show up on all of the friends and pages’ Facebook Timelines, resulting in more distribution for your site.
There’s a lot of functionality such as publishing on your timeline, adding like/send/subscribe buttons and there are also easy to use widgets available.
