"Google is now showing what they call \"sub-sitelinks\" for some searchers in the search results.  Sitelinks are the links you find under a search result that show links to popular pages within the site.  This often comes up for navigational searches, for example a search on [search engine roundtable] and tons of other queries.Google is now showing some searchers sub-sitelinks, so sitelinks for sitelinks.  Here is an example of it in action provided by Google Operating System blog.  As you can see by the animated GIF I made, the sitelinks show with arrows down, when clicked, they show secondary sitelinks.Here is a larger image provided by @6cSocial:This is not the first mention of Sub-Sitelinks. In fact, we had this show in Google Webmaster Tools back in October 2009 and then Google made mention of it in May 2012 by saying:\"Sub-sitelinks\" in expanded sitelinks. [launch codename \"thanksgiving\"] This improvement digs deeper into megasitelinks by showing sub-sitelinks instead of the normal snippet.I personally do not see sub-sitelinks and the people who have, only have seen it on the mobile search results.Forum discussion at Google+ &amp; Twitter.Update: This is now official, Google's search blog covered it."^^<http://www.w3.org/2001/XMLSchema#string>
