Google Sitelinks
 

However nobody knows why Google makes Sitelinks for some websites ans why it doesn't make for others, i guess some parameters are important for having Sitelinks in Google and they are Pagerank and traffic.
I want to know other parameters that you know to have Sitelinks in Google?

I would try to design site-links that make navigation easy for users. This type of internal linking is what Google looks for.

It also helps your website more attractive in Google Search Engine.

Total is the entire page links every page on the site you do link, and link is relative and total home page for links, generally is the large-scale web link will distinguish, and usually small web site will do very little to distinguish. Site is the highest weight home page, the distribution of the inside pages weight is less, but large-scale web pages related to weight is also very high.
