How To Customize Yoast SEO Breadcrumbs in WordPress

The Yoast SEO plugin is a popular choice for optimizing content for search engines, and it includes a feature for generating breadcrumbs. Breadcrumbs are a navigational aid that helps users understand the site structure and easily navigate back to previous pages.

This hook allows users to add a custom “Blog” link in the Yoast SEO breadcrumb when viewing a single entry, providing a more personalized and convenient navigation experience.

Code:

// Add a filter to modify Yoast SEO breadcrumb links
add_filter( 'wpseo_breadcrumb_links', 'yoast_seo_breadcrumb_blog_append_link' );

// Callback function to modify breadcrumbs
function yoast_seo_breadcrumb_blog_append_link( $links ) {

    // Check if the current page is a single post
    if ( is_singular( 'post' ) ) {
        // Create a new breadcrumb item for the blog
        $breadcrumb[] = array(
            'url' => site_url( '/blog/' ), // You can specify any link; in this example, it leads to a static "blog" page
            'text' => 'Blog', // The display text for the breadcrumb item
        );

        // Insert the new breadcrumb item after the first item (usually "Home") and remove all items starting from the second to the second-to-last
        array_splice( $links, 1, -2, $breadcrumb );
    }

    // Return the modified breadcrumbs
    return $links;
    
}
