AgilePress Schema JSON-LD Block

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:

• Clean Editor Interface: Displays only a visual placeholder in the editor, keeping your workspace uncluttered
• Sidebar Editing: All JSON-LD editing happens in the Block Sidebar via InspectorControls
• Template Library: Pre-built templates for common schema types including LocalBusiness, Organization, and FAQ
• Real-time Validation: Instant JSON validation feedback as you type
• Dynamic Placeholders: Support for WordPress core placeholders and ACF custom fields
• SEO Optimized: Outputs clean JSON-LD markup via wp_head for optimal search engine parsing

Supported Placeholders:

• {{title}} – Post/page title
• {{excerpt}} – Post excerpt
• {{date}} – Publication date
• {{url}} – Current post URL
• {{featured_image_url}} – Featured image URL
• {{acf:field_name}} – Any ACF field (supports strings and arrays)

Template Options:

1. Blank – Start from scratch
2. LocalBusiness – Perfect for local business listings
3. Organization – For company/organization information
4. FAQ – Structured FAQ markup

The block uses dynamic rendering to process placeholders on the frontend, ensuring your structured data always reflects current content.

Technical Details

The block uses a dynamic rendering approach with render_callback to process placeholders server-side. This ensures that:

• Placeholders are replaced with current data on every page load
• ACF fields are safely accessed and formatted
• Invalid JSON never reaches the frontend
• Search engines receive clean, valid JSON-LD markup

The frontend output is optimized with no extra paragraph or break tags, outputting only the pure JSON-LD script tag.
