I am sure this question has been asked before but, I don't know how recently. Is GSA Search Engine Ranker still relevant in SEO today? I am thinking about purchasing it and using it but, will it hurt or help my website if I use GSA to build tier 1 and tier 2 backlinks? Also, can I use GSA to only build keyword relevant backlinks on HIGH PR webpages and not on spammy low PR webpages? Lastly, what would the total cost come to for GSA, a good VPN, and 10 private proxies?
