<h3>Introduction to Structured Data</h3>
<p>Structured data markup describes things on the web, along with their properties. For example, if your site has recipes, you could use markup to describe properties for each recipe, such as the summary, the URL to a photo for the dish, and its overall rating from users.</p>
<p>When you provide structured data markup for your online content, you make that content eligible to appear in two categories of Google Search features:</p>
<ul>
<li><strong>Rich results</strong> — Structured data for things like recipes, articles, and videos can appear in Rich Cards, as either a single element or a list of items. Other kinds of structured data can enhance the appearance of your site in Search, such as with <a href="https://developers.google.com/search/docs/data-types/breadcrumbs" rel="nofollow ugc">Breadcrumbs</a>, or a <a href="https://developers.google.com/search/docs/data-types/sitelinks-searchbox" rel="nofollow ugc">Sitelinks Search Box</a>.</li>
<li><strong>Knowledge Graph cards</strong> — If you’re the authority for certain content, Google can treat the structured data on your site as factual and import it into the <a href="http://www.google.com/intl/es419/insidesearch/features/search/knowledge.html" rel="nofollow ugc">Knowledge Graph</a>, where it can power prominent answers in Search and across Google properties. Knowledge Graph cards appear for authoritative data about <a href="https://developers.google.com/search/docs/data-types/corporate-contacts" rel="nofollow ugc">organizations</a>, and <a href="https://developers.google.com/search/docs/data-types/events" rel="nofollow ugc">events</a>. <a href="https://developers.google.com/search/docs/data-types/reviews" rel="nofollow ugc">Movie reviews</a>, and <a href="https://developers.google.com/search/docs/data-types/tv-movies" rel="nofollow ugc">movie/music play actions</a>, while based on ranking, can also appear in Knowledge Graph cards once they are reconciled to Knowledge Graph entities.</li>
</ul>

<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:description – The excerpt of your post/page (compatible with “wpSEO” and “All in One SEO Pack”)</li>
<li>og:site_name – The title of website.</li>
<li>og:locale – The locale these tags are marked up in.</li>
<li>og:image – An image URL (featured image if exists) which should represent your post/page</li>
</ul>
<h4>For post only</h4>
<ul>
<li>article:tag – Tag words associated with your post.</li>
</ul>
