Google Updates Rich Snippets
Google has introduced two updates to rich snippets including global support of product rich snippets and HTML input inclusion in rich snippet testing tool.
Product Rich Snippets
Product rich snippets give us the ability to display price, availability, ratings and similar extra information to our core snippet. Now this feature is supported globally, and no longer restricted to select locales.
