Schema Markup: Complete Implementation Guide

What is Schema Markup?

Schema markup is a semantic vocabulary of tags that you can add to your HTML to improve the way search engines read and represent your page in SERPs.

Why Schema Markup Matters

• Enhanced search results: Rich snippets with images, ratings, and more
• Knowledge panels: Appear in Google's knowledge graph
• Voice search optimization: Better understanding for voice assistants
• Click-through rates: More attractive search results

Schema Markup Formats

JSON-LD (Recommended)

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Article Title",
  "author": {
    "@type": "Person",
    "name": "Author Name"
  }
}
</script>

Microdata

<div itemscope itemtype="https://schema.org/Article">
  <h1 itemprop="headline">Article Title</h1>
  <span itemprop="author" itemscope itemtype="https://schema.org/Person">
    <span itemprop="name">Author Name</span>
  </span>
</div>
