Rich objects in a social graphs
When you share a link on Facebook, an image from the link is shown, usually. Sometimes, no image is displayed, as if Facebook couldn’t find a suitable image at the URL.
Adding Open Graph protocol tags to your site will ensure that Facebook knows which image to use when someone shares a page on your website. Open Graph markup is similar to schema.org markup. Both allow you to define values for certain aspects of your website, as seen by other sites like Facebook, Twitter, and many other social media sites.

og:type property to
website. A list of other Open Graph protocol object types can be found at the Open Graph protocol site.
Every Open Graph property will be set on-the-fly, depending on which post or page is being viewed or shared. To add the necessary markup, we need to use the add_action WordPress function inside your theme’s
functions.php file. Here’s how I’ve been handing it:
