Link juice within a site

Hi, If a PR5 site with for example 100 pages were to link to my site from a page other than the home page would i still get as much link juice as i would than from a site with say 10 pages. The reason i ask this is because i am adding a page to my site which links to my partners site, will this link be devalued with it being buried in my site. Also is it worth adding "nofollow" to pages such as contact and about us to add more link juice withinh my site.

Thanks in advance

No... If done right the more pages you add to your website which are quality pages, with good content and link bait ideas, then the more links you will get. So essentially you SHOULD get more link juice flowing through your website via deep pages etc. This is a big factor in google, if not biggest. They love it.

If you're asking if the deep page link on the 10 page site will help you more than a deep link on a 100 page site (both PR5) obviously the 10 page site would be better. If its a sitewide link the 100 page would be better. If the content on the site is unique, well written, matches your site I wouldn't even worry to much about the PR. The SERPs gods will reward you.

The link juice your site gets from another site depends on the PR of the Page your link is on.

Also the value of links from deep pages is not reduced by the fact that they are deep pages. However a links page ie a page with many outgoing links does not have as much value as a stand alone link within the content of a page

If you are worrried about leaking PR then yes you should add the no follow attribute to links from your page, however I think it is only fair that your link partners are aware of this
