Schema Markup & Structured Data (JSON-LD)

Speaking Machine Code to Search Engines

Structured Data (using Schema.org vocabulary in JSON-LD format) provides explicit data clues to search engines about the meaning of a page.

Example: Course Schema in JSON-LD

Adding this script block into your HTML head allows Google to display rich snippet details (star ratings, price, duration, provider) directly on the SERP:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Course",
  "name": "Digital Marketing & SEO Essentials",
  "description": "Learn search engine mechanics, keyword research, meta tags, and analytics.",
  "provider": {
    "@type": "Organization",
    "name": "DocHero"
  },
  "isAccessibleForFree": true
}
</script>
