Sometimes you have a different permalink set up than the breadcrumbs you want. 
For instance: http://yourdomain.com/seo-services 
The “seo-services” page is under the “services” section but you did not set it up as a child of the services page. 
Still, you want the breadcrumbs to indicate the proper parent. 
Example: 
Home > Services > SEO Services 
instead of: 
Home > SEO Services
This plugin lets you do that. 
It has no settings but adds a side meta box to all your posts and pages (All post types) where you can choose the title and url to prepend to the breadcrumbs trail. 
Options are: 
-Append a breadcrumb after the first breadcrumb (Usually “Home”) 
-Prepend a breadcrumb to the last item in the breadcrumbs (the current page). 
A title and URL need to be entered for each pair in order for the breadcrumbs to be affected. You can create 2 new breadcrumbs or just one.

RDFa Breadcrumb provide links back to each previous page the user navigated through to get to the current page or – in hierarchical site structures – the parent pages of the current one.
It gives you a new template tag called <code>rdfa_breadcrumb()</code> that you can place anywhere in your template files. It has inbuilt RDFa content markup, so this will help Google to recognize and display the breadcrumbs on search results as well.
Check out the screenshots.
