🎯 Rich Results

Enable rich snippets, FAQs, and knowledge panels

📈 Higher CTR

Increase click-through rates by 25-35%

🤖 Better Understanding

Help Google understand your content context

🌟 Featured Snippets

Increase chances of appearing in position zero

Setting Up Rank Math for JSON-LD

Install and Activate Rank Math

Go to Plugins → Add New → Search "Rank Math SEO" → Install → Activate

Run Setup Wizard

Follow the guided setup and enable Schema (Structured Data) module

Configure Global Schema

Go to Rank Math → Titles & Meta → Schema (Structured Data) tab

Set default schema type for posts, pages, and custom post types

Add Schema to Individual Posts

Edit any post → Scroll to Rank Math meta box → Schema tab

Choose schema type (Article, NewsArticle, BlogPosting, etc.)

💡 Pro Tip: Use "Article" schema for blog posts, "Product" for WooCommerce items, and "LocalBusiness" for business websites.

Method 2: Manual JSON-LD Implementation (Advanced)

For developers who want full control, manual implementation offers maximum flexibility:

Adding JSON-LD to WordPress Header

// Add to your theme's functions.php file
function add_jsonld_schema() {
    if (is_single()) {
        global $post;
        echo '<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "' . esc_js(get_the_title()) . '",
  "description": "' . esc_js(get_the_excerpt()) . '",
  "author": {
    "@type": "Person",
    "name": "' . esc_js(get_the_author_meta('display_name')) . '"
  },
  "datePublished": "' . esc_js(get_the_date('c')) . '",
  "dateModified": "' . esc_js(get_the_modified_date('c')) . '",
  "publisher": {
    "@type": "Organization",
    "name": "' . esc_js(get_bloginfo('name')) . '"
  }
}
</script>';
    }
}
add_action('wp_head', 'add_jsonld_schema');
            

WooCommerce Product Schema Example

// Add to functions.php for WooCommerce products
function add_product_jsonld() {
    if (is_product()) {
        global $product;
        echo '<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "' . esc_js($product->get_name()) . '",
  "description": "' . esc_js($product->get_short_description()) . '",
  "brand": {
    "@type": "Brand",
    "name": "' . esc_js(get_bloginfo('name')) . '"
  },
  "offers": {
    "@type": "Offer",
    "price": "' . esc_js($product->get_price()) . '",
    "priceCurrency": "' . esc_js(get_woocommerce_currency()) . '",
    "availability": "https://schema.org/' . ($product->is_in_stock() ? 'InStock' : 'OutOfStock') . '"
  }
}
</script>';
    }
}
add_action('wp_head', 'add_product_jsonld');
            

⚠️ Important: Always use esc_js() to escape JavaScript output and prevent XSS vulnerabilities.

Common WordPress JSON-LD Mistakes to Avoid

❌ Incorrect schema types: Using Article for products
❌ Missing required fields: Incomplete organization data
❌ Invalid JSON syntax: Commas, brackets errors
❌ Not testing: Deploying without validation

Advanced: Dynamic JSON-LD for Custom Post Types

// Advanced example for custom post types
function add_custom_post_type_schema() {
    if (is_singular('your_custom_post_type')) {
        $schema = array(
            '@context' => 'https://schema.org',
            '@type' => 'YourSchemaType',
            'name' => get_the_title(),
            'description' => get_the_excerpt(),
            // Add custom fields
            'customField' => get_post_meta(get_the_ID(), 'your_meta_key', true)
        );
        
        echo '<script type="application/ld+json">' . 
             json_encode($schema, JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT) . 
             '</script>';
    }
}
add_action('wp_head', 'add_custom_post_type_schema');
            

Performance Considerations

JSON-LD should not impact page speed when implemented correctly:

✅ Place JSON-LD in <head> section
✅ Minify JSON-LD code (remove unnecessary whitespace)
✅ Use efficient plugins or manual implementation
✅ Avoid duplicate schema markup
✅ Consider lazy-loading for non-critical schema
