Breadcrumb Schema Markup

Structured data helps search engines understand breadcrumbs and display them as rich snippets.

JSON-LD Implementation

{
  "@context": "https://schema.org",
  "@type": "BreadcrumbList",
  "itemListElement": [
    {
      "@type": "ListItem",
      "position": 1,
      "name": "Homepage",
      "item": "https://example.com/"
    },
    {
      "@type": "ListItem",
      "position": 2,
      "name": "Categories",
      "item": "https://example.com/categories/"
    },
    {
      "@type": "ListItem",
      "position": 3,
      "name": "Electronics",
      "item": "https://example.com/categories/electronics/"
    },
    {
      "@type": "ListItem",
      "position": 4,
      "name": "Smartphones",
      "item": "https://example.com/categories/electronics/smartphones/"
    }
  ]
}

Microdata Implementation

<nav aria-label="Breadcrumb">
  <ol itemscope itemtype="https://schema.org/BreadcrumbList">
    <li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">
      <a itemprop="item" href="https://example.com/">
        <span itemprop="name">Homepage</span>
      </a>
      <meta itemprop="position" content="1" />
    </li>
    <li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">
      <a itemprop="item" href="https://example.com/categories/">
        <span itemprop="name">Categories</span>
      </a>
      <meta itemprop="position" content="2" />
    </li>
    <li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">
      <span itemprop="name">Electronics</span>
      <meta itemprop="position" content="3" />
    </li>
  </ol>
</nav>

HTML Implementation

Semantic HTML

<nav aria-label="Breadcrumb" class="breadcrumb">
  <ol class="breadcrumb-list">
    <li class="breadcrumb-item">
      <a href="/" class="breadcrumb-link">Homepage</a>

    <li class="breadcrumb-separator" aria-hidden="true">></li>
    <li class="breadcrumb-item">
      <a href="/categories/" class="breadcrumb-link">Categories</a>
    </li>
    <li class="breadcrumb-separator" aria-hidden="true">></li>
    <li class="breadcrumb-item">
      <a href="/categories/electronics/" class="breadcrumb-link">Electronics</a>
    </li>
    <li class="breadcrumb-separator" aria-hidden="true">></li>
    <li class="breadcrumb-item breadcrumb-current" aria-current="page">
      Smartphones
    </li>
  </ol>
</nav>
