I have using GSA with SEREngies and Kontent Machine to build tier 1, tier 2,tier 3 for my money site about two weeks, it generate ~50 backlinks for each tier per day. But I find the ranking are not improved. (I am using 5 dedicate proxy with 50 threads on my personal gaming laptop). I am not sure I did right.
I also find some threads suggested using personal web 2.0 with hand write content as tier 1,is that still working in 2018?
what is the average time to take new site's keyword(medium diffculty) into top 3? (which software can help analysis the keyword difficult? )
Thanks for sharing your experience.
