X3P0: Breadcrumbs is the most robust breadcrumb navigation system for WordPress. Built on 15+ years of development, it automatically detects your permalink structure and displays accurate breadcrumbs for every page on your site.
Perfect for improving site navigation and SEO, this breadcrumbs plugin works seamlessly with both block themes and classic themes. Simply insert the Breadcrumbs block via the WordPress Site Editor or add it to your theme templates.
<h4>Key Features</h4>
Automatic Site Structure Detection
The plugin automatically detects your permalink setup and builds breadcrumbs based on your site’s hierarchy. No configuration needed–it just works out of the box. But you can also customize if you need to change it.
Custom Post Type Support
Automatically recognizes custom post types and custom taxonomies created by other plugins or your theme. Whether you’re running an ecommerce solution, a portfolio site, or any custom setup, breadcrumbs will display correctly.
Block Theme and Classic Theme Compatible
Insert breadcrumbs using the WordPress block editor in any template, template part, or pattern. For classic themes, easily add breadcrumbs using a simple PHP function call.
Developer Customization
Built on a robust object-oriented PHP foundation with extensive hooks and filters. Developers can customize every aspect of breadcrumb generation and display.
Schema.org Structured Data Support
Choose from plain HTML, Schema.org microdata, or RDFa formats for optimal SEO and search engine visibility.
Flexible Display Options
Control which breadcrumb items display, customize separators, hide breadcrumbs on specific pages, and style breadcrumbs to match your theme.
<h4>How to Add Breadcrumbs to Your Site</h4>
For Block Themes:
<ol>
<li>Go to Appearance → Editor</li>
<li>Open your Header template part (or any template where you want breadcrumbs)</li>
<li>Click the block inserter (+) and search for “Breadcrumbs”</li>
<li>Insert the block and customize settings in the block sidebar</li>
<li>Save your template</li>
</ol>
The breadcrumbs will automatically display site-wide based on your permalink structure.
For Classic Themes:
Add this code to your <code>header.php</code> or any template file where you want breadcrumbs to appear:
<pre><code><?= do_blocks('') ?>
</code></pre>
<h4>SEO Benefits</h4>

<h4>Supported Content Types</h4>

<li>Blog posts with category breadcrumbs</li>
<li>Custom post types (products, portfolios, etc.)</li>

</ul>

<li>Custom crumb classes for specialized breadcrumb items</li>
<li>Filter hooks for modifying which breadcrumbs are shown</li>
</ul>
<h4>How It Works</h4>
This breadcrumbs plugin analyzes the current WordPress query and generates breadcrumbs based on:
<ol>
<li>Your permalink structure – Date-based, post name, category-based, or custom</li>
<li>Content hierarchy – Parent pages, category relationships, custom taxonomies</li>
<li>Post type configuration – Custom post type archives and relationships</li>
<li>Taxonomy settings – Primary categories and taxonomy hierarchies</li>
</ol>
The plugin automatically detects these settings and builds the most accurate breadcrumb trail for each page, so you don’t need to configure complex rules.
<h4>Developer Documentation</h4>
For developers who want to customize breadcrumbs programmatically, the plugin provides extensive PHP classes and hooks. See the <a href="https://github.com/x3p0-dev/x3p0-breadcrumbs" rel="nofollow ugc">GitHub repository</a> for full developer documentation.
<h4>Why Choose X3P0: Breadcrumbs?</h4>
