Hello Guys, Currently I am working on my site with my personal SEO methods and till now I am getting good keyword movement. Now I would like to know how many ways we can make tiered link building? Means which links should we send to 2nd tiers with which keywords? Suppose on 1st tier I made manual web 2.0 blogs, high pr bookmarks,social signals with main keywords. Now for 2nd tier should I target all of the above or just web 2.0 is sufficient with same main keywords along with generic keywords combined? Currently I am targeting only web 2.0 for comment blast. So is there any advantages on targeting social signals,bookmarks etc in 2nd tier? Also I would like to know what are the possible ways we can provide additional link juice? Also what tier 1 platforms you would like to suggest to add it in my arsenal?
