I'm a very beginner with GSA and I was wondering something about building links. I've read a lot of posts, threads and people opinions and some people say it's better as a beginner to focus on building high PR links, quality, with low OBL and others say to blast it as quick as possible, and I have doubts what to do now, I've been trying to make my decision for 2 days so far and I need your help BHW. Do I go for high PR links with low OBL only (low LpM ofc) or I go for more links? Also, what type of links do you recommend for tier 1 beside web 2.0? And one more question, as a beginner of GSA, how do I work with tiered link building? Thank you.
