<p>Automagically adds Open Graph tags to your blog. Control how your posts and pages are presented on Facebook and other social media sites. No configuration needed.</p>
<p>When someone likes or shares your blog on Facebook, your header image is shown. If someone likes or shares a post, the featured image (post thumbnail) is shown. If you haven’t selected a featured image, then the plugin looks for the first image inside the post. If there aren’t any images in your post, then your blog’s header image is shown.</p>

<p>This plugin adds several Open Graph Meta Elements to the header of your theme for blog posts and pages to avoid no thumbnail, wrong title / description issue etc. It is compatible with the WordPress SEO plugins “wpSEO” and “All in One SEO Pack”. When a title or description is stored by one of these SEO plugins, WP Open Graph Meta will use them.</p>
<p>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.</p>
<p>To turn your posts and pages into graph objects, the plugin adds the following meta elements to webpage header:</p>
<h4>For post/page</h4>
<ul>
<li>og:title – The title of your post/page (compatible with “wpSEO” and “All in One SEO Pack”)</li>
<li>og:type – The type of your post/page. Depending on the type it is possible to specify automatically other properties.</li>
<li>og:url – The canonical URL of your post/page</li>

<li>og:site_name – The title of website.</li>
<li>og:locale – The locale these tags are marked up in.</li>
