Our site just got a site from an internal page of a pr 10 website. It is www.xyz.com/category/subcat/page.html. The page on which the link is placed does not have a pr. Toolbar shows white 0/10. Seems they have delibrately done so. But other pages in the directory have pr8. Also when I do a google search of the domain my website shows up. Will this give a boost to my pr?
