Robots.txt or Rel=Nofollow for Blocking Web Pages from Indexing

Q: Confusion about robots.txt vs rel=nofollow. I don’t want to pass PageRank to my Privacy Policy. Suppose I already blocked /privacy/ in my robots.txt. Do I also have to use rel=nofollow when linking internally to /privacy/ to prevent the pass of PageRank?

A: (Susan Moskwa): Pages that are blocked by robots.txt can still have and pass PageRank, so if you don’t want that page to get PageRank from your Privacy Policy page, you should nofollow that link.
