OZ FAQ Block adds a lightweight and accessible Gutenberg block for creating FAQ sections with collapsible answers. It’s optimised for SEO and outputs valid schema.org JSON-LD markup (FAQPage), helping your content become eligible for rich results in Google.
No external libraries, no bloat — just a native editing experience. You can reorder questions, style the layout with your own CSS, and extend the output easily via PHP.
Ideal for documentation pages, product FAQs, help centres, or blog posts with structured Q&A content.
<h3>Usage</h3>
<ol>
<li>Open any post or page in the block editor (Gutenberg)</li>
<li>Click “Add block” (+) and search for “FAQ Block”</li>
<li>Add your questions and answers directly in the editor</li>
<li>Optionally reorder or remove items</li>
<li>Save the page – the block automatically outputs structured FAQPage markup</li>
</ol>

Adds custom field to the post & pages editor for custom JSON-ld schema markup also known as structured data. The plugin also validates if the JSON is formated correctly. <a href="http://coderisk.com/wp/plugin/websitescanner-custom-schema/RIPS-8iSfZmxGFd" rel="nofollow ugc"></a>
Add your own JSON-ld on every page, post and custom post without the <code><script></code> to show your own custom Schema markup.
Works well with the following plugins:
<ul>
<li><a href="https://wordpress.org/plugins/remove-schema/" title="Remove Schema WordPress plugin" rel="ugc">Remove Schema</a></li>
</ul>
Usecases:
With the combination of the WordPress plugin it’s easy to overwrite the schema on a specific page. 
If a plugin like Yoast SEO or other plugin or theme that generates schema you can disable the schema and add your own custom schema to the page.
