Welcome all I was wondering if there are any specific kinds of links that boost your site well. What I have learned till now: - Contextual links are best. - Nofollow : Do-follow 60% : 40% is a good ratio. - As big as possible diversity on anchors and about 20% noncontextual anchors (like "click here") as well as about 20% links linking to root domain instead of niche URL. - Contextual Nofollow links are extremely hard to get (correct me if you know a way to do this). What I am wondering about: - Do amounts of likes/tweets/+1s of social post give any power to the link included? - Do social posts pass do-follow link juice? - Are link blasts still working and how is blasting Tier 1 different from "making Tier 2"? And important one: - How do I tell if a link is good or bad? I currently check TF but I have noticed some chinese spammy sites to have incredible high TF. If I am wrong in any of the above, or if you know any answer to these that would help me (and not only) in ranking then I would highly appreciate if you share your knowledge.
