Do you think GSA SER still useful in 2017 after so many changes in Google algorithms? Long ago in 2006 even when I was using BMD only (with no proxy setting changed whatsoever), I still remember my website got high jump in SERP within overnight and it stayed there till end of last year (2016). Then now I turn to GSA SER and seems to have super slow effect.
What is your experience using GSA SER in 2017? Is it still effective to boost SERP?
