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.

Structured data allows developers and publishers to mark up content in a way that it’s easy for machines to understand. Proper use of structured data <a href="https://developers.google.com/search/docs/guides/intro-structured-data" rel="nofollow ugc">enables third-parties like Google to parse reviews, event data, and contact information in meaningful ways</a>, ensuring you’re getting the most “bang” out of your publishing buck.
Fortunately, the major players in the Search game, including Google, Microsoft, Yahoo!, and Yandex) came together in the early 2010s to form <a href="http://schema.org/docs/about.html" rel="nofollow ugc">Schema.org</a>, a collaborative, community-driven standard for structured data.
With the major search engines and communities behind it, we’re all marking up everything with appropriate structured data now, right?
Unfortunately, the process of implementing Schema.org in a site — especially one driven by dynamic content — is less than straightforward. <a href="https://wordpress.org" rel="ugc">WordPress</a>, for instance, <a href="https://ma.tt/2015/11/seventy-five-to-go/" rel="nofollow ugc">powers roughly a quarter of the web</a>, but implementing structured data across hundreds of thousands of themes would be a nightmare.
Or, at least it would be, if it weren’t for Schemify.
<h4>What does Schemify do?</h4>
There are two approaches to adding structured data to a website: via the markup or <a href="http://json-ld.org/" rel="nofollow ugc">JSON for Linking Data (JSON-LD)</a>.
Consider the following author information, which might appear at the bottom of a blog post:
<pre><code> 
 
 <a href="https://stevegrunwell.com" rel="author nofollow ugc">Steve Grunwell</a>
 Steve is the Director of Technology at Growella. When he's not working, you can find him speaking at conferences, roasting coffee, or spending time with his wife and daughter
 
</code></pre>
If I wanted this information to use Schema.org markup, it would look something like this:
<pre><code> 
 
 <a href="https://stevegrunwell.com" rel="author nofollow ugc">Steve Grunwell</a>
 Steve is the Director of Technology at Growella. When he's not working, you can find him speaking at conferences, roasting coffee, or spending time with his wife and daughter
 
</code></pre>
While that may not seem like a lot of work, that’s still a lot of extra markup being added. Even worse, a lot of that markup might normally be generated by WordPress helper functions like <a href="https://developer.wordpress.org/reference/functions/get_avatar/" rel="nofollow ugc"><code>get_avatar()</code></a>, which means extra work to get the necessary <code>itemprop</code> attribute in place.
Fortunately, the other approach for adding structured data is much more straight-forward in a theme, as it’s simply a JSON-LD object:
<pre><code> 
 {
 "@context": "http://schema.org",
 "@type": "Person",
 "name": "Steve Grunwell",
 "url": "https://stevegrunwell.com",
 "image": "https://secure.gravatar.com/avatar/88ea4e10ed968136228545d7112d82cb?s=200",
 "description": "Steve is the Director of Technology at Growella. When he's not working, you can find him speaking at conferences, roasting coffee, or spending time with his wife and daughter"
 }
 
</code></pre>
We simply generate this JSON-LD object and append it to our document’s <code><body></code>. When Google or anyone else who supports JSON-LD structured data parses our page, they can immediately understand that Steve Grunwell is a person and determine his website, avatar, and biography.
The best part? There’s no need to change the markup within our theme!
Schemify aims to automate the generation of JSON-LD objects for content within WordPress. Its flexible structure and reasonable defaults enables drop-in support for structured data, regardless of the WordPress theme.
