Hi, I am a newbie for seo, and really learnt a lot from this great blackhatworld. thank you. Now I got a question puzzled, if we build up links from blogs by commenting and leave key word as anchor text, they are all relevant to the key word, but they are no follow tags, it would help the good serch ranking position? or Not? 1. Relevance with no follow tag 2. No releavance with do follow tag Compare with 1 and 2, which is good? thank you.
