As the title states, I'm interested in learning more about how to identify a Google manual reviewer. I realize a lot of this will be speculative, though if anyone has any real insight feel free to PM me. I know Goog hires "at home" workers at least in part for manual reviewing. My question is whether or not those reviewers are required to log into a Google VPN that could be easily identified....or if they use random Residential IPs. I'm looking to correlate manual reviews with ranking fluctuations, as well as forecast niches in which Goog seems to be more "proactive" in the number of reviews they conduct per month.
