Google said that starting today they have updated their “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.” Google has actually been testing this for a few years now, it was not uncommon for searchers to see these tests over the past few years. With that, they are giving webmasters a way to better communicate the site name and breadcrumb data through structured data schema. The schema markup to specify the site name can be found here and the schema for breadcrumb can be found here. It is basically a little extra markup you can add to your source code in order to communicate these variables to Google. Get the full story at Search Engine Land
