Cutts says: don’t use nofollow within your site
There is always a lot of discussion on using nofollow within your site for Pagerank Sculpting purposes. Matt Cutts now talked about it in his video responses. He says: let it flow naturally. He even thinks it doesn’t hurt to have the login page in the search results. I disagree with him on that one. Not for search purposes, but for conversion purposes. Check out what Matt said and tell me what you think.
