When you look up “post office” in Google, the first link you get is for the US postoffice, and there is a nice menu below it that describes the main menu in the Post office website.
What kind of HTML directives do I need to put into a page in order to get such a menu in search engines?
Another question: how can I verify quickly it works, once I add the HTML directives? Will I have to wait for the next crawl of a search engine to see what it would look like?
Thanks!
Webmaster.google.com is a good place to start
