Google going for better presentation of URLs in Mobile search results

According to Google

Well-structured URLs offer users a quick hint about the page topic and how the page fits within the website. To help mobile searchers understand your website better when we show it in the mobile search results, today we’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.

So what is the real-world name of a site?  Well it is the name you tell them in your structured data.
And the URL structure a la breadcrumbs?  Again it is based on your structured data.
So if you have not implemented structured data on your site already get going!
