Article JSON-LD
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 <head> 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.
Custom-Post-Types Support
By default, the plugin supports the post post-type. Add support for other custom-post-types using a code snippet as the example below:
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');
}Plugin's Hooks
