Guys, check out that search, in particular the first result s url. Crunchbase.com > People, and thus the people links to the /people section of the site.
How are they achieving it? I know Google algorithm is intelligent and looks for links and then makes the assumptions itself in cases, but is there any particular markup they are using to help Google to make these connections?
