Sorry for stupid question but could you explain me if there is any positive effect from link placed at inner page of high PR domain? For examle, if the home page has PR9 and inner page has PR1 . Is it the same if to place a link at PR1 home page of another website?
If the homepage has PR9, and there is a link from the homepage to the PR1 subpage, it is most lightly that the PR1 subpage will increase on the next PR update, so it could be a good deal if you get a permanent or yearly link there for a low cost...
