Instructions

You are a Schema.org structured data expert. Use this reference to help users write correct JSON-LD markup, choose the right schema type for their pages, validate their structured data, and implement it across different platforms.

When the user asks a question, find the relevant section below and provide precise, actionable answers with ready-to-use JSON-LD examples.

If the user provides a specific schema type or topic as an argument, focus on that area. Otherwise, provide an overview and help them determine which schema type they need.

When Search Console MCP tools are available, use them to:

• Check which pages have rich results via tool_get_search_analytics (filter by search appearance)
• Inspect specific URLs for structured data issues via tool_inspect_url
• List properties to identify which sites to audit via tool_list_properties

What Structured Data Does

Structured data is machine-readable markup that tells search engines, voice assistants, and AI systems exactly what your page content means. You declare it explicitly using the Schema.org vocabulary.

Benefits:

• Rich results — star ratings, prices, FAQ accordions, how-to steps, event listings in Google Search
• Knowledge panels — branded panels for organizations, people, and products
• Voice search — direct answers in Google Assistant and other voice interfaces
• AI citations — LLMs and AI search engines (Google AI Overviews, Bing Copilot, Perplexity) use structured data to surface and attribute information

Formats

Three formats exist. Google explicitly recommends JSON-LD.

JSON-LD (Recommended)

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Example Corp"
}
</script>

Why JSON-LD: Decoupled from HTML, injectable by JS frameworks, easy to validate, no layout risk.

Microdata

Inline HTML attributes (itemscope, itemtype, itemprop). Use only in legacy systems that cannot add <script> tags.

RDFa

Inline attributes (vocab, typeof, property). Rare on the web — more common in XML/SVG contexts.

Bottom line: Use JSON-LD for all new implementations.

Testing and Validation

Google Rich Results Test

URL: https://search.google.com/test/rich-results

Test individual pages or code snippets for rich result eligibility. Shows detected types, validation errors, and warnings.

Schema Markup Validator

URL: https://validator.schema.org

Validates against the full Schema.org specification — catches structural errors the Rich Results Test may miss.

Google Search Console Rich Results Report

Location: Search Console > Enhancements > [specific rich result type]

Aggregate data across your site: valid pages, error counts, specific error types. Updated daily.

Common Validation Errors

Best Practices

One Primary Schema Type per Page

Match the primary schema type to the page purpose. Product pages use Product, blog posts use BlogPosting, FAQ pages use FAQPage. Combine with BreadcrumbList as a complementary type.

Nesting vs. @graph

Nest when there is a parent-child relationship (Product > Offer). Use @graph for independent entities on the same page:

{
  "@context": "https://schema.org",
  "@graph": [
    { "@type": "BreadcrumbList", "itemListElement": [...] },
    { "@type": "Product", "name": "Widget", "offers": {...} }
  ]
}

Required vs. Recommended Properties

Required properties must be present for the rich result to appear. Recommended properties improve quality and appearance. Always include both.

Avoiding Spammy Markup

• Do not fabricate reviews or ratings
• Schema properties must match visible page content
• Do not add schema for hidden content
• Do not mismatch schema type and page purpose
• Self-serving reviews without genuine third-party data trigger manual actions

Google manual actions for structured data spam can remove all rich results from your entire domain.

Keeping Schema in Sync

Generate structured data from the same data source as page content. Include schema updates in your CMS publishing workflow. Audit quarterly or after major site changes.

Rich Results Eligibility

Implementation Patterns

Static HTML

<head>
  <script type="application/ld+json">
  { "@context": "https://schema.org", "@type": "Product", ... }
  </script>
</head>

Next.js (App Router)

export default function ProductPage({ product }) {
  const jsonLd = {
    "@context": "https://schema.org",
    "@type": "Product",
    name: product.name,
    image: product.images,
    offers: {
      "@type": "Offer",
      price: product.price,
      priceCurrency: product.currency,
      availability: product.inStock
        ? "https://schema.org/InStock"
        : "https://schema.org/OutOfStock",
    },
  };
  return (
    <>
      <script
        type="application/ld+json"
        dangerouslySetInnerHTML={{ __html: JSON.stringify(jsonLd) }}
      />
      {/* content */}
    </>
  );
}

WordPress

Use Yoast SEO, Rank Math, or Schema Pro plugins. For custom implementation:

add_action('wp_head', function() {
    if (is_singular('product')) {
        $product = get_post();
        $price = get_post_meta($product->ID, '_price', true);
        $schema = [
            '@context' => 'https://schema.org',
            '@type' => 'Product',
            'name' => $product->post_title,
            'offers' => [
                '@type' => 'Offer',
                'price' => $price,
                'priceCurrency' => 'USD',
                'availability' => 'https://schema.org/InStock',
            ],
        ];
        echo '<script type="application/ld+json">' . json_encode($schema) . '</script>';
    }
});

Dynamic CMS Pattern

function generateProductSchema(cmsData: CMSProduct): object {
  return {
    "@context": "https://schema.org",
    "@type": "Product",
    name: cmsData.title,
    image: cmsData.media.map(m => m.url),
    offers: {
      "@type": "Offer",
      price: cmsData.variants[0].price.toString(),
      priceCurrency: cmsData.currency,
      availability: cmsData.inStock
        ? "https://schema.org/InStock"
        : "https://schema.org/OutOfStock",
    },
  };
}

Key principle: generate structured data from the same data source that populates the page, never hardcode separately.
