Hello ! I am browsing google and i don't know how to make this: It looks like some sub categories of website. Is there any way to do it ?
I'm guessing you are talking about sitelinks... http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=47334 You cannot do anything to "make" them happen other than having a clear navigation structure for your site. But even then, Google is going to decide when they show up and which URLs are included. If you don't like what they choose, you can block them from showing a particular URL in Webmaster Tools. But that's about all the control you have.
you just have to wait for it , register for google webmaster services , it takes lots of time , only sites that are old
This is sitelinks and it is based on the traffic to you sub-pages. In WMT, there is a section on this. They give you the option to use or not use their selection of a item. Note: Any page that is gray barred will not ever be displayed.
