JSON-LD for AI Search: Complete Guide

JSON-LD is the preferred structured data format for helping AI search engines understand your content's type, authorship, relationships, and factual claims.

Why JSON-LD for AI Search

JSON-LD helps AI systems:

• Understand what type of content a page contains
• Identify the author and their credentials
• Parse relationships between entities
• Extract structured facts (prices, dates, specs)
• Verify content authority

Essential Schema Types

Article Schema

{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "What Is GEO?",
  "author": {
    "@type": "Organization",
    "name": "Geodocs Team",
    "url": "https://geodocs.dev"
  },
  "datePublished": "2025-04-25",
  "dateModified": "2025-04-25",
  "publisher": {
    "@type": "Organization",
    "name": "Geodocs.dev"
  },
  "description": "GEO is the practice of structuring content for AI citation."
}

Organization Schema

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your Organization",
  "url": "https://yoursite.com",
  "logo": "https://yoursite.com/logo.png",
  "sameAs": [
    "https://twitter.com/yourorg",
    "https://linkedin.com/company/yourorg"
  ]
}

HowTo Schema

{
  "@context": "https://schema.org",
  "@type": "HowTo",
  "name": "How to Create llms.txt",
  "step": [
    {
      "@type": "HowToStep",
      "name": "Create the file",
      "text": "Create a plain text file named llms.txt"
    },
    {
      "@type": "HowToStep",
      "name": "Add content",
      "text": "Add your site name and key page URLs"
    }
  ]
}

Implementation Steps

1. Identify page type — Article, Product, FAQ, HowTo, etc.
2. Choose the schema — Match Schema.org type to content
3. Write the JSON-LD — Include all required properties
4. Add to page — Place in <script type="application/ld+json">
5. Validate — Test with Google Rich Results Test
6. Monitor — Check Search Console for errors

Best Practices

Common Mistakes

1. Using generic WebPage — Use specific types (Article, HowTo, FAQ)
2. Missing author — AI values attributed content
3. No dateModified — AI needs freshness signals
4. Inconsistent entities — Same organization name everywhere
5. Invalid JSON — Always validate before deploying
