I checked out google about what no follow/Do follow is. I think I understand but I would like someone to clarify some stuff for me. First some things about linking: 1 - If I put a link on my blog post leading to my home page, does that help me rank up higher? 2 - If I put Nofollow on that link, will it not help with my ranking? 3 - Should I skip commenting on blogs that has no follow on all their links? Some? Or does this matter? 4 - Is there a good add-on for firefox I can use that tells me if a blog is using nofollow? Thanks.
