One of the problems when generating breadcrumbs for posts is that you need to create a single breadcrumbs path for display purpose. But, in many cases, single post can have multiple categories, tags and even terms for custom taxonomies. And, a single breadcrumb can’t contain all that information.
So, what can you do? Well, GD Crumbs Navigator Pro can generate group of breadcrumbs to include all possible paths leading to the current or selected post. If your post has 5 categories and 3 tags you will get total of 11 breadcrumbs: 5 for categories, 3 for tags and 3 for dates based archives.
Image on the right shows the multi breadcrumbs generated for a single post. Function or shortcode for multi breadcrumbs allow you to control which elements will be used to generate the multi breadcrumbs paths. And, if you don’t want to use date based archives, disable them from displaying.
This method is similar to what Amazon uses to display products and list categories where each product is located.
With this method you can improve internal links on your website, and each breadcrumb can still use rich snippets, and Google can pick up multiple breadcrumbs too.
