WPSSO – Social Media Plugins for wordpress

WPSSO is a plugin that works behind the scenes to make sure your WordPress website contains valid Open Graph and Schema Markup, among other things. This helps ensure that when your content is shared on social media, it’s properly read by services like Facebook, Pinterest, and Twitter. For example, this information will make sure that Twitter Cards grab the right images, etc.

Even more advanced features are available in the Pro version of the plugin.
