These include meta information such as site name, a description (the excerpt of a post), the permalink, author, categories and images for your post.

Open Graph tags will be used by social network sites such as Facebook, Twitter or Google+ to style a shared link or webpages "liked" by any user. Images supposedly attract more attention, so you might find this plug-in useful.
