Schema Markup Guide: Add Structured Data to Your Website

Summary: How to add schema markup for rich snippets in Google. Step-by-step with examples.

By SiteAuditFast·

What is Schema Markup?

Schema markup is JSON-LD code that tells search engines exactly what your content means.

**Quick answer:** Add JSON-LD schema to your HTML head to get rich snippets in Google — FAQs, star ratings, prices, and more.

Why Schema Matters

Without schema: plain blue link with title and description.

With schema: star ratings, FAQ dropdowns, prices — more space, more clicks.

Rich snippets can increase click-through rate by 20-30%.

Most Impactful Schema Types

  • FAQPage — expandable Q&As directly in Google results
  • LocalBusiness — address, hours, phone in search results
  • Product — price and star ratings in shopping results
  • Article — author and publish date for blog posts
  • SoftwareApplication — ratings and pricing for web apps
  • How to Add Schema

    Add to your HTML head:

    <script type="application/ld+json">{ your JSON-LD here }</script>

    Then test with Google Rich Results Test tool.
