Adds a “Test Data” link in the admin bar (when viewing any page or post) which opens the current URL in <a href="https://search.google.com/structured-data/testing-tool" rel="nofollow ugc">Google’s Structured Data Testing Tool</a>. (You must have the admin bar enabled to see it.)
<h3>Introduction to Structured Data</h3>
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.
When you provide structured data markup for your online content, you make that content eligible to appear in two categories of Google Search features:
<ul>
<li>Rich results — 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>Knowledge Graph cards — 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>

Content Cards make ordinary web links great by making it possible to embed a beautiful Content Card to link to any web site.
By using OpenGraph data, Content Cards grabs the title, description and associated image to the links you embed – it’s similar to how you can embed other websites, such as YouTube, Twitter, SoundCloud and more.
For individual links, You can insert a Content Card via shortcode <code>[contentcards url="http://yoursite.com/article-1"]</code>. If you often use Content Cards for some website, you can register the domain name (for example: <code>yoursite.com</code>) as an oEmbed provider via Plugin’s Settings page and then it will behave the same way other oEmbed providers do – you will just have to paste plaintext link to a separate paragraph an Content Card will be generated automatically.
