RichSnippets can have very positive impact on the Click-Through-Rate of your Website on Google or any searchengine. With this plugin it is possible to generate a breadcrumb navigation with the microdata format from schema.org. This navigation will be shown on your webpage and the snippets on the search engine result pages.
Until the next release this Plugin works mainly with Themes that have a menu navigation at the top of the page like Zerif Lite.
