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.

<h4>Why this plugin exists</h4>
Original Plugin (discontinued): https://de.wordpress.org/plugins/json-ld-for-article/
Sadly, the original plugin is not being developed anymore. So I decided to fix some bugs like invalid markup, 
 missing tags, putting objects into fields instead of just URLs for images, and implementing for more than just 
 articles.
Also, this plugin plays nicely with <a href="https://de.wordpress.org/plugins/yet-another-stars-rating/" rel="nofollow ugc">YASR – yet another star rating</a>. It will 
remove yasr’s invalid jsonld-syntax and instead use YASRs rating.
All requests are being cached and purged on page update/edit etc.

<h4>Original description</h4>
Search engines such as Google are using structured data markup in many ways—for example, to create rich snippets in search results. Search results with rich snippets will improve your click through rates and increase the number of visitors on your website.
It has been a tedious task to add the complicated Schema.org markup to your website – sometimes it wasn’t even possible due to technical constraints. Now, thanks to JSON-LD, almost any website can enjoy the benefits of structured data. For WordPress users it’s even easier thanks to this plugin.
JSON-LD for Article is simply the easiest solution to create valid schema.org microdata markup on your WordPress site automatically from your web content and its metadata. All you need to do is install and activate the plugin, and it will generate JSON-LD markup of your posts that Google and other search engines can use for rich snippets using the schema.org for articles.
Some WP themes include traditional schema.org markup embedded in the html code the theme produces. If you are using one of these themes, this plugin is probably not necessary. If the markup produced by the theme contradicts the data specified in the JSON-LD, the added information might be not be helpful at all. Thus you should check the markup provided by the theme before adding possibly unnecessary JSON-LD to your site.
On the other hand, if you use a custom theme, it is easier to use the functionality provided by the plugin than to invent the wheel again and add the markup in html. Very often, this leads to html code that is difficult to read and is not valid structural markup according to Google’s validator.
Our plugin:
<ul>
<li>Helps your site to earn rich snippets in Google’s SERP.</li>
<li>Does not depend on other plugins or external code.</li>
<li>Is simple to install: plug-and-play, no need to configure anything.</li>
</ul>

wp-jsonld is the continuation of the simplest solution to add valid schema.org microdata as JSON-LD-script to your blog posts and articles.
