Using functions.php

Add schema to specific post types:

// Add Article schema to blog posts
function add_article_schema() {
    if (is_single() && get_post_type() === 'post') {
        global $post;

        $schema = array(
            '@context' => 'https://schema.org',
            '@type' => 'Article',
            'headline' => get_the_title(),
            'datePublished' => get_the_date('c'),
            'dateModified' => get_the_modified_date('c'),
            'author' => array(
                '@type' => 'Person',
                'name' => get_the_author()
            ),
            'publisher' => array(
                '@type' => 'Organization',
                'name' => get_bloginfo('name'),
                'logo' => array(
                    '@type' => 'ImageObject',
                    'url' => get_site_icon_url()
                )
            )
        );

        if (has_post_thumbnail()) {
            $schema['image'] = get_the_post_thumbnail_url($post, 'full');
        }

        echo '<script type="application/ld+json">' .
             json_encode($schema, JSON_UNESCAPED_SLASHES) .
             '</script>';
    }
}
add_action('wp_head', 'add_article_schema');

Using a Custom Plugin

Create a simple plugin for schema:

<?php
/**
 * Plugin Name: Custom Schema Markup
 * Description: Adds custom JSON-LD schema markup
 * Version: 1.0
 */

function custom_organization_schema() {
    if (is_front_page()) {
        $schema = array(
            '@context' => 'https://schema.org',
            '@type' => 'Organization',
            'name' => 'Your Company Name',
            'url' => home_url(),
            'logo' => 'https://example.com/logo.png',
            'sameAs' => array(
                'https://facebook.com/yourpage',
                'https://twitter.com/yourhandle',
                'https://linkedin.com/company/yourcompany'
            )
        );

        echo '<script type="application/ld+json">' .
             json_encode($schema, JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT) .
             '</script>';
    }
}
add_action('wp_head', 'custom_organization_schema');

Using Blocks (Gutenberg)

Add schema via custom HTML blocks:

Add Custom HTML block
Paste your schema:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "Your question?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Your answer."
      }
    }
  ]
}
</script>

Schema for WooCommerce

Built-in Schema

WooCommerce includes basic Product schema automatically.

Enhanced Product Schema

Use WooCommerce-specific plugins:

Yoast WooCommerce SEO - Premium product schema
Rank Math - Free WooCommerce schema
Schema Pro - Advanced product markup

Custom WooCommerce Schema

function enhanced_product_schema($markup, $product) {
    // Add additional properties
    $markup['brand'] = array(
        '@type' => 'Brand',
        'name' => get_the_terms($product->get_id(), 'product_brand')[0]->name ?? ''
    );

    return $markup;
}
add_filter('woocommerce_structured_data_product', 'enhanced_product_schema', 10, 2);

FAQ Schema with Plugins

Using Rank Math

Edit post in Gutenberg
Add “FAQ by Rank Math” block
Enter questions and answers
Schema is auto-generated

Using Yoast (Premium)

Add Yoast FAQ block
Enter Q&A pairs
Schema is auto-generated

Recommended Setup

For Most Sites

Install Rank Math (free) or Yoast SEO
Configure Organization schema in settings
Set Article schema for posts
Use FAQ blocks for FAQ content
Add Product schema for e-commerce

For Advanced Needs

Use Schema Pro for complex requirements
Add custom code for specific schemas
Use our JSON-LD Schema Generator for one-off pages

Testing Your WordPress Schema

After Implementation

Use Rich Results Test
Check various page types (posts, pages, products)
Verify in Google Search Console

Common Issues

Conflicting schema from multiple plugins
Missing images in Article schema
Outdated plugin generating old schema formats

Best Practices

Use one schema solution - Don’t mix multiple plugins
Test regularly - Check after updates
Monitor Search Console - Watch for errors
Keep plugins updated - Schema requirements change
Validate before publishing - Test important pages

Generate Custom Schema

For pages not covered by plugins, use our JSON-LD Schema Generator:

Generate the schema you need
Copy the JSON-LD code
Add via Custom HTML block or functions.php
Validate with Rich Results Test

Conclusion

WordPress makes schema implementation accessible to everyone. For most sites, a quality SEO plugin like Rank Math or Yoast provides sufficient schema automation.

For advanced needs, combine plugin functionality with custom code or dedicated schema plugins. Always test your implementation and monitor Search Console for issues.

The key is consistency—choose one approach and implement it thoroughly rather than mixing multiple solutions.
