Hello friends, I am little confused about pagerank sculpting. what is it? what does it? please reply me.
PR sculpting is using internal linking on your site to channel PR to pages you want to rank. The larger your site, the more effect you see out of PR sculpting. Smaller sites won't see much benefit. If I remember correctly, the original concept was created by Leslie Rohde some 5-6 years ago.
Yes, as "Miroslav" said it's all about ranking your targeted inner pages. In simple, you should conserve your home page PR by inter linking less important inner pages with "no-follow" attributes. So that, your home page PR link juice will only pass to pages that you would like to rank.
