I want to go for a very competitive keyword but I dont want to waste my time if it's manually reviewed. I have checked everybody on page 1 and nobody is doing anything that is obviously blackhat. either the sites are ranking naturally, or they are using very clean PBNs containing sites that look like real sites. How can I find out if this is manually reviewed? because I dont want to waste time ranking it just to have it taken away from me in a couple of days.
