Food for Search

Pagerank sculpting is a well-know link strategy that some websites adopt. Basically they nofollow links to pages on their site where they don’t want the link juice to flow, the link love to spread. For instance their contact page. I personally don’t really agree with this method as every single page of a website carries at least one link, I really see a site as a whole where less performing pages or CCTLDs will benefit from the stronger ones. I know many inhouse SEOs use this strategy, but to what extent should they push it?
