How does Google Search do "menu" results?
Does anyone out there know how the menu style search result that often accompanies the top hit on the results page happens? I'm referring to the way the top result often breaks out to hot links for "contact us" "about us" etc, beyond the basic link to the home page. I'm wondering if this happens automatically somehow, and how does one cause it to happen in web page design--- or is it something the companies pay google for?
thanks!
