I am trying to SEO 1 small low competitor keywords, but I am not good in building backlink with GSA. I read this: http://forum.gsa-online.de/discussion/comment/18224/#Comment_18224He share his tier 1 and tier 2 to everyone. But he said: If i build links to micro niche websites or any other new websites i just turn Tier 2 into Tier 1. So that means I have to build link with only 1 tier? I'm confused right now. Should I build link follow his advice? If not, can you suggest me for a good campaign?
