I heard that for better PR of the homepage the site needs to be structured like this :
- the homepage links to all pages, and every single page links to the homepage.
- the homepage links to second level pages and they links to third level pages, and every single page links to only one upper level page.
my questions is :
1. is it right ?
2. if site designed that every page links to all pages (with sidebar etc.), is it smart to make all extraneous links rel=nofollow ?
