Google has announced today that in order to help mobile searchers understand your website better in mobile search results they’re updating the algorithms that display URLs in the search results to better reflect the names of websites, using the real-world name of the site instead of the domain name, and the URL structure of the sites in a breadcrumbs-like format.
These changes are rolling out gradually and affect only mobile results.
