Wordpress: Generate SEO-Friendly Breadcrumbs

Breadcrumbs are a great way to improve both user experience and SEO by providing a clear site navigation path. This snippet generates SEO-friendly breadcrumbs dynamically based on the user's path through the site.

The function hooks into WordPress's content display system to insert breadcrumb navigation accurately reflecting the user's current location in the site hierarchy.

Implementation includes using post data and taxonomy terms to construct a breadcrumb trail, with links to each preceding section up to the home page.

The snippet also integrates schema.org markup to enhance SEO further, making the breadcrumbs more useful to search engines.

Customization options for styling and filtering the breadcrumbs output are discussed to ensure they integrate seamlessly with various theme designs.
