I've used services like LinkEmperor in the past (2013) for diversity purposes and things went really well other then the fact that once you quit their services your sites WILL tank. (link loss penalty). I also know just buying normal everyday link blasts won't work as well as they did in the past. What I did with a couple of my sites (past couple months, 1st page rankings for low comp keywords) is just buying junky web2.0 and blog comments spam from a website (not going to state it anywhere for anyone). It just doesn't seem very how do I put it... Effective? Also those links tend to drop like flies but the OBL is extremely low (huge plus compared to buying GSA ser lists). How would you recommend I outsource and/or automate my backlinking (for just diversification)?
