Hi guys. I started a new autority site and I want to start a few web 2.0 to warm them up before I put a few backlinks. I wanted to base my strategy in this post http://www.blackhatworld.com/blackh...web2-0-structures-yourself-simple-method.html but I dont know if this is working right now, since the post is 2 yars old. What do u think? Its worth the time or should I only concetrate myself (more expensive) in PBN backlinks? Plus, I have posted content since 3 weeks and only appear in first 100 of google for 5% of my KW. Is this normal nowadays? How long should a wait to start worring? How long to wait to build safe backlinks? Thanks in advance guys!!
