I am a new SEO (I'm in this filed for while however i was mainly building sites not actively trying to rank sites on super competitive niches). I read on many places that GSA, ScrapeBox and FCS Networker are very useful for SEO and i brought then along with proxy for 1 year. Yeah, i spend quite a lot of money. however, i want to know from an expert how should i use them for maximum ROI in 2017 and beyond. I know about tire 2, tier 3 and all that, basically i exactly want to know how i should use them and for what.
