AgilePress

AgilePress Schema JSON-LD Block is a sophisticated block for adding Schema.org structured data to your WordPress posts and pages. It provides a clean, user-friendly interface for managing JSON-LD markup without cluttering your content editor.
Key Features:
<ul>
<li>Clean Editor Interface: Displays only a visual placeholder in the editor, keeping your workspace uncluttered</li>
<li>Sidebar Editing: All JSON-LD editing happens in the Block Sidebar via InspectorControls</li>
<li>Template Library: Pre-built templates for common schema types including LocalBusiness, Organization, and FAQ</li>
<li>Real-time Validation: Instant JSON validation feedback as you type</li>
<li>Dynamic Placeholders: Support for WordPress core placeholders and ACF custom fields</li>
<li>SEO Optimized: Outputs clean JSON-LD markup via wp_head for optimal search engine parsing</li>
</ul>
Supported Placeholders:
<ul>
<li><code>{{title}}</code> – Post/page title</li>
<li><code>{{excerpt}}</code> – Post excerpt</li>
<li><code>{{date}}</code> – Publication date</li>
<li><code>{{url}}</code> – Current post URL</li>
<li><code>{{featured_image_url}}</code> – Featured image URL</li>
<li><code>{{acf:field_name}}</code> – Any ACF field (supports strings and arrays)</li>
</ul>
Template Options:
<ol>
<li>Blank – Start from scratch</li>
<li>LocalBusiness – Perfect for local business listings</li>
<li>Organization – For company/organization information</li>
<li>FAQ – Structured FAQ markup</li>
</ol>
The block uses dynamic rendering to process placeholders on the frontend, ensuring your structured data always reflects current content.
<h3>Technical Details</h3>
The block uses a dynamic rendering approach with <code>render_callback</code> to process placeholders server-side. This ensures that:
<ul>
<li>Placeholders are replaced with current data on every page load</li>
<li>ACF fields are safely accessed and formatted</li>
<li>Invalid JSON never reaches the frontend</li>
<li>Search engines receive clean, valid JSON-LD markup</li>
</ul>
The frontend output is optimized with no extra paragraph or break tags, outputting only the pure JSON-LD script tag.

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.
