Page Rank is not same as traffic ranking ........ but if a site is highly ranked means it has lotsa inbound links which we can conclude will bring more traffic as well.
For a diectory example, see the popular BlogCatalog ... go to any category and any listing ......... for example this >>
http://www.blogcatalog.com/blogs/derrichcom.html ........ right click and view source......There's a link to this site
http://www.derrich.com ......but the link has the rel="nofollow" attribute.
So, if you want to know, you'll have to go the directory of your choice, and view the source to see how links are constructed
