The <a href="https://ogp.me/" rel="nofollow ugc">Open Graph protocol</a> enables any web page to become a rich object in a social graph. Most notably, this allows for these pages to be used with Facebook’s <a href="https://developers.facebook.com/docs/reference/plugins/like" rel="nofollow ugc">Like Button</a> and <a href="https://developers.facebook.com/docs/reference/api/" rel="nofollow ugc">Graph API</a> as well as within Twitter posts.
The Open Graph plugin inserts the Open Graph metadata into WordPress posts and pages, and provides a simple extension mechanism for other plugins and themes to override this data, or to provide additional Open Graph data.
This plugin does not directly add social plugins like the Facebook Like Button to your pages (though they’re pretty simple to add). It will however make your pages look great when shared using those kinds of tools.

This WordPress plugin makes a link tile from Open Graph protocol. 
What you have to write is just a shortcode:
[khlt_linktile url=”URL”]
And there are some options.
<ul>
<li>url : (mandatory) URL to link</li>
<li>bgcolor : (option, default: #fff) background-color of the link tile.</li>
<li>nocache : (option, default: false) set to true once if the linked page is changed.</li>
<li>desc : (option, default: fetch from OGP) set any text here if you want to override OGP’s description.</li>
</ul>
OGP data from linked site is cached for a week. (You can change my PHP code)
