What Is JSON-LD? Complete Technical Overview & Schema Standard

JSON-LD is a lightweight data serialization format for embedding structured data in web pages using a script tag. It provides a standardized way for search engines to interpret page entities without altering the visual HTML markup.

Key Technical Takeaways

  • ✓Separated from HTML: Lives inside <script type="application/ld+json"> blocks in the <head>.
  • ✓Google Recommended: Explicitly preferred over Microdata and RDFa by search engines.
  • ✓Powers Rich Results: Unlocks FAQ dropdowns, star ratings, article metadata, and breadcrumb lists.

Implementation Example

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "WebSite",
  "name": "Open Graph Generator",
  "url": "https://opengraphgenerator.com"
}
</script>
