The Open Graph protocol enables any web page to become a rich object in a social graph. For instance, this is used on Facebook to allow any web page to have the same functionality as any other object on Facebook.
To turn your posts and pages into graph objects, the plugin add the following metadata to webpage header:
og:title - The title of your post/page.
og:description - The excerpt of your post/page.
og:image - URL of featured image (if exists) which represent your post/page.
og:site_name - The title of website.
og:url - The canonical URL of your post/page.
