I'm very experienced using blog networks to rank my sites and it's going well for me. However, there are affiliate sites I constantly see that are just KILLING it for huge keywords and I know these sites are making thousands per day. All of these sites are using a huge amount of mass links that are obviously being built with GSA, SENuke, or something else. Everyone I have hired to run GSA for me sucks and cannot rank my site, or they just get it penalized. Are there any products out there with real information on how to use mass links as your first tier? I can't find any no matter where I look. Apparently this info is only known to few.
