Learning objectives#

  • Write JSON-LD with schema.org types
  • Add breadcrumbs and article markup
  • Validate with Google’s tools
  • Follow accuracy guidelines

Explanation#

JSON-LD (a <script type="application/ld+json"> block) is the recommended format. Vocabulary comes from schema.org.

Common types: Article/TechArticle, BreadcrumbList, Organization, Product (with Offer and Review), Event, LocalBusiness, VideoObject.

Rich results are not guaranteed; Google decides. Some features change over time (FAQ rich results are now shown only for a limited set of authoritative sites).

Markup must match visible content. Fake ratings or invisible content can lead to manual actions.

Code example: Article + breadcrumbs#

HTMLArticle + breadcrumbs Illustrative
<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@graph": [
    {
      "@type": "TechArticle",
      "headline": "SQL INNER JOIN with Examples",
      "dateModified": "2026-10-29",
      "author": { "@type": "Organization", "name": "Techie Babaji" },
      "publisher": { "@type": "Organization", "name": "Techie Babaji", "url": "https://techiebabaji.com" }
    },
    {
      "@type": "BreadcrumbList",
      "itemListElement": [
        { "@type": "ListItem", "position": 1, "name": "Home", "item": "https://techiebabaji.com/" },
        { "@type": "ListItem", "position": 2, "name": "SQL Server", "item": "https://techiebabaji.com/tutorials/sql-server" },
        { "@type": "ListItem", "position": 3, "name": "INNER JOIN" }
      ]
    }
  ]
}
</script>
Expected output
The Rich Results Test detects a valid Breadcrumb and Article; search results can show the breadcrumb trail.

This example is illustrative. Copy or download it and run it in your own environment; the expected output is shown above.

Step-by-step explanation#

  1. @graph holds several entities in one block.
  2. TechArticle describes the lesson and its update date.
  3. BreadcrumbList mirrors the visible breadcrumb.
  4. Validate before and after deploying.

Real-world use case#

An online shop’s product pages show price and availability in search results thanks to accurate Product markup.

Common mistakes#

Marking up content users cannot see

Violates guidelines and can trigger penalties.

Fake reviews or ratings

Never invent ratings to get stars in results.

Best practices#

  • Use JSON-LD
  • Only accurate, visible information
  • Validate with Rich Results Test
  • Monitor enhancements in Search Console

Remember this#

JSON-LD + schema.org.

Must match visible content.

Eligibility ≠ guarantee.

Practice exercise#
