    },
    {
      "@type": "WebSite",
      "@id": "https://example.com/#website",
      "url": "https://example.com",
      "name": "Site Name",
      "publisher": { "@id": "https://example.com/#organization" }
    },
    {
      "@type": "WebPage",
      "@id": "https://example.com/page/#webpage",
      "url": "https://example.com/page/",
      "name": "Page Title",
      "isPartOf": { "@id": "https://example.com/#website" }
    },
    {
      "@type": "Article",
      "mainEntityOfPage": { "@id": "https://example.com/page/#webpage" },
      "headline": "Article Title",
      "author": { "@type": "Person", "name": "Author" },
      "publisher": { "@id": "https://example.com/#organization" },
      "datePublished": "2025-01-15"
    },
    {
      "@type": "BreadcrumbList",
      "itemListElement": [
        { "@type": "ListItem", "position": 1, "name": "Home", "item": "https://example.com" },
        { "@type": "ListItem", "position": 2, "name": "Blog", "item": "https://example.com/blog" },
        { "@type": "ListItem", "position": 3, "name": "Article Title" }
      ]
    }
  ]
}

Generation Process

When the user asks for schema markup:

Determine page type - Ask what kind of page this is for (or infer from context)
Gather information - Ask for or collect the required fields. If the user provides a URL, fetch it to extract data.
Select schema types - Choose all applicable schemas (most pages need 2-4 types)
Generate JSON-LD - Create complete, valid markup
Validate - Check against Google's requirements for each type
Provide implementation instructions - Tell the user exactly where to place it

Implementation Instructions

For Next.js App Router:

// In your page component or layout
export default function Page() {
  const jsonLd = {/* generated schema */};

  return (
    <>
      <script
        type="application/ld+json"
        dangerouslySetInnerHTML={{ __html: JSON.stringify(jsonLd) }}
      />
      {/* page content */}
    </>
  );
}

For Next.js with next/head (Pages Router):

import Head from 'next/head';

export default function Page() {
  const jsonLd = {/* generated schema */};

  return (
    <>
      <Head>
        <script
          type="application/ld+json"
          dangerouslySetInnerHTML={{ __html: JSON.stringify(jsonLd) }}
        />
      </Head>
      {/* page content */}
    </>
  );
}

For plain HTML:

<head>
  <script type="application/ld+json">
  {/* generated schema */}
  </script>
</head>

Validation

After generating the markup, remind the user to validate using:

Google Rich Results Test: https://search.google.com/test/rich-results
Schema.org Validator: https://validator.schema.org/

Common Mistakes to Avoid

Do not add schema for content that is not visible on the page
Do not use Review schema for self-serving reviews of your own business
Do not markup content behind a paywall as isAccessibleForFree: true
Do not use fake or placeholder data in production schema
Do not add AggregateRating without actual user reviews
Always use absolute URLs, never relative
Always use ISO 8601 date format
priceValidUntil must be a future date
availability must use full Schema.org URL (e.g., https://schema.org/InStock)
Image URLs must be crawlable and indexable
