Blog Schema: JSON-LD Structured Data Generation

Generates complete, validated JSON-LD schema markup for blog posts using the @graph pattern. Combines multiple schema types into a single script tag with stable @id references for entity linking.

Workflow

Step 1: Read Content

Read the blog post and extract all schema-relevant data:

• Title (headline)
• Author (name, job title, social links, credentials)
• Dates (datePublished, dateModified / lastUpdated)
• Description (meta description)
• FAQ section (question and answer pairs)
• Images (cover image URL, dimensions, alt text; inline images)
• Organization info (site name, URL, logo)
• Word count (approximate from content length)
• Tags/categories (for BreadcrumbList category)
• Slug (from filename or frontmatter)

Step 2: Generate BlogPosting Schema

Complete BlogPosting with recommended properties when applicable:

{
  "@type": "BlogPosting",
  "@id": "{siteUrl}/blog/{slug}#article",
  "headline": "Concise post title",
  "description": "Concise page-specific meta description",
  "datePublished": "YYYY-MM-DD",
  "dateModified": "YYYY-MM-DD",
  "author": { "@id": "{siteUrl}/author/{author-slug}#person" },
  "publisher": { "@id": "{siteUrl}#organization" },
  "image": { "@id": "{siteUrl}/blog/{slug}#primaryimage" },
  "mainEntityOfPage": {
    "@type": "WebPage",
    "@id": "{siteUrl}/blog/{slug}"
  },
  "wordCount": 2400,
  "articleBody": "First 200 characters of content as excerpt..."
}

Google's Article structured data docs do not define required Article properties. Include headline, datePublished, author, publisher, and image when applicable, validate with the Rich Results Test, and treat missing fields as warnings unless the target surface requires them. Recommended properties: description, dateModified, mainEntityOfPage, wordCount, articleBody (excerpt).

Step 3: Generate Person Schema

Author schema with stable @id for cross-referencing:

{
  "@type": "Person",
  "@id": "{siteUrl}/author/{author-slug}#person",
  "name": "Author Name",
  "jobTitle": "Role or Title",
  "url": "{siteUrl}/author/{author-slug}",
  "sameAs": [
    "https://twitter.com/handle",
    "https://linkedin.com/in/handle",
    "https://github.com/handle"
  ]
}

Optional properties (include when available):

• alumniOf - Educational institution (Organization type)
• worksFor - Employer (reference to Organization @id if same entity)

Step 4: Generate Organization Schema

Blog's parent organization entity:

{
  "@type": "Organization",
  "@id": "{siteUrl}#organization",
  "name": "Organization Name",
  "url": "{siteUrl}",
  "logo": {
    "@type": "ImageObject",
    "url": "{siteUrl}/logo.png",
    "width": 600,
    "height": 60
  },
  "sameAs": [
    "https://twitter.com/org",
    "https://linkedin.com/company/org",
    "https://github.com/org"
  ]
}

Logo requirements: use a valid crawlable image URL and follow the active Organization and Article documentation for the target surface. Do not invent hard logo dimensions unless the project or current docs require them.

Step 5: Generate BreadcrumbList

Navigation breadcrumb schema showing content hierarchy:

{
  "@type": "BreadcrumbList",
  "@id": "{siteUrl}/blog/{slug}#breadcrumb",
  "itemListElement": [
    {
      "@type": "ListItem",
      "position": 1,
      "name": "Home",
      "item": "{siteUrl}"
    },
    {
      "@type": "ListItem",
      "position": 2,
      "name": "Category Name",
      "item": "{siteUrl}/blog/category/{category-slug}"
    },
    {
      "@type": "ListItem",
      "position": 3,
      "name": "Post Title",
      "item": "{siteUrl}/blog/{slug}"
    }
  ]
}

If no category is available, use "Blog" as the second breadcrumb item with {siteUrl}/blog as the URL.

Step 6: Generate FAQPage Entity Schema

Extract Q&A pairs from the blog post's FAQ section:

{
  "@type": "FAQPage",
  "@id": "{siteUrl}/blog/{slug}#faq",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "What is the question?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "The complete answer text (40-60 words with statistic)."
      }
    }
  ]
}

Important note: Google retired FAQ rich results for all sites on 2026-05-07. FAQPage is not a Google rich result path. Only emit FAQPage when visible FAQ content exists, with at least one valid Question and matching visible answer. Treat it as entity clarity markup, not a Google rich-result promise. The Article/BlogPosting schema remains the priority for blog search eligibility.

Step 7: Generate VideoObject (if videos present)

For each YouTube video embedded in the post, generate a VideoObject schema:

{
  "@type": "VideoObject",
  "@id": "{siteUrl}/blog/{slug}#video-{index}",
  "name": "Video title",
  "description": "Video description excerpt (first 200 chars)",
  "thumbnailUrl": "https://img.youtube.com/vi/{videoId}/hqdefault.jpg",
  "uploadDate": "{ISO 8601 date}",
  "contentUrl": "https://www.youtube.com/watch?v={videoId}",
  "embedUrl": "https://www.youtube.com/embed/{videoId}",
  "duration": "PT{M}M{S}S",
  "interactionStatistic": {
    "@type": "InteractionCounter",
    "interactionType": { "@type": "WatchAction" },
    "userInteractionCount": {viewCount}
  }
}

Add each VideoObject to the @graph array. Use #video-1, #video-2 etc. for the @id fragment. Extract video metadata from the embed's noscript fallback or from YouTube Data API if available via blog-google.

Step 7.5: Generate ImageObject

Cover image schema for the post's primary image:

{
  "@type": "ImageObject",
  "@id": "{siteUrl}/blog/{slug}#primaryimage",
  "url": "https://cdn.pixabay.com/photo/.../image.jpg",
  "width": 1200,
  "height": 630,
  "caption": "Descriptive caption matching alt text"
}

Image requirements:

• URL must be crawlable and publicly accessible
• Width and height should reflect actual image dimensions
• Caption should match or closely align with the image alt text
• Preferred dimensions: 1200x630 (OG-compatible) or 1920x1080

Step 8: Validate & Warn

Check per-surface support before recommending schema types:

Validation checks:

1. All @id references resolve to entities within the @graph
2. dateModified is equal to or after datePublished
3. headline is concise. Warn when it may truncate or becomes unclear
4. description is concise, page-specific, and not duplicated across posts
5. All URLs are absolute (not relative)
6. Image dimensions are positive integers
7. BreadcrumbList positions are sequential starting from 1
8. If FAQPage is emitted, visible Q&A content exists and includes at least 1 valid Question

AI citation optimization note: Relevant schema helps entity clarity and rich-result eligibility where supported, but structured data is not required for Google generative AI search visibility. Prioritize Article/BlogPosting, Person, Organization, and BreadcrumbList. Add ImageObject or VideoObject when assets exist, and add FAQPage only when visible FAQ content exists.

Step 9: Output

Combine all schemas into a single <script> tag using the @graph pattern:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@graph": [
    { "@type": "BlogPosting", ... },
    { "@type": "Person", ... },
    { "@type": "Organization", ... },
    { "@type": "BreadcrumbList", ... },
    { "@type": "FAQPage", ... },
    { "@type": "VideoObject", ... },
    { "@type": "ImageObject", ... }
  ]
}
</script>

@graph pattern benefits:

• Single script tag instead of multiple - cleaner HTML
• Entity linking via stable @id references (e.g., author references Person by @id)
• Google and AI systems parse @graph arrays correctly
• Easier to maintain and update as a single block

Output options:

• Embedded HTML - Ready to paste into <head> or before </body>
• Standalone JSON - For CMS schema fields or API injection
• MDX component - If the project uses MDX, wrap in a component

Save the generated schema to the blog post file or to a separate schema file as the user prefers.
