Article JSON-LD is an extendable and straightforward solution to enhance your site SEO by adding Schema.org microdata as a JSON-LD script on your site posts.
It will automatically insert the JSON-LD script in your site <code><head></code> tag by using the standard information provided by WordPress, such as the title, description, featured image, publish date, author, categories..etc.
You can support your custom post types or modify the data easily by using the plugin’s hooks.
<h4>Custom-Post-Types Support</h4>
By default, the plugin supports the <code>post</code> post-type. Add support for other custom-post-types using a code snippet as the example below:
<pre><code>add_action('init', 'add_article_json_ld_post_type_support', 15);

/**
 * @return void
 */
function add_article_json_ld_post_type_support()
{
 add_post_type_support('custom-post-type', 'article-json-ld');
}
</code></pre>
You can use <a href="https://wordpress.org/plugins/code-snippets" rel="ugc">Code Snippets</a> plugin to add the code snippets to your site.

What is Microdata?
The job of microdata, is to hold the hand of a search engine, and take it directly to the data that you need it to find. This helps search engines understand what it is crawling and minimise mistakes.
Major search engines, like Google, now support something called the <a href="http://schema.org/" rel="nofollow ugc">schema.org</a> vocabulary for structured data. In English, it is a universal template for structuring data. Essentially this makes it easier for search engines to crawl your pages. As a human being, we are able to fill in the blanks when we view information, but software like search engines require a helping hand.
One of the ways the schema.org vocabulary can be embedded within a page, is by using microdata. There are different sets for whatever your page is referring to. In the case of selling products, you would use the <a href="http://schema.org/Product" rel="nofollow ugc">Product Schema</a>. If you are familiar with metadata, then think of it like that. In the HTML of your page code, you wrap the text in the same way.
What does this plugin do?
This plugin allows you to embed Schema.org Microdata for PostingBlog. But rather than pre-fill this information using other plugins, it automatically pulls the information from your Article and your WordPress Settings so that you don’t have to do anything.
The microdata won’t be shown on the page, but instead just within the footer using meta tags. This means that the page will be optimised for search engines without having to add text to the page.
Supported Schema.org
This plugin is currently limited to PostingBlog Schema.
