I’ve a question for you. How should building link for some blogs with the safest way? Is this have to use rel=”follow’? Is nofollow link useless? If you pay more attention to submit my articles to social bookmarking websites like digg, mixx, folkd, and yahoo! buzz, is this will affect / have effect to my sites, which it means Google will count it as inbound links? Thank you very much for the answer.
