Anybody else noticed this over the past couple of days? My linking strategies are quite conservative, and over the past 6 months competitior sites who are buying thousands of links walked right past me in the serps. Now I am seeing some big link buyers dropping by 3 or 4 positions all of a sudden. Could it be that Google is finally rewarding people who follow its guidelines? Or just a quirk that will right itself in a few days time? I know sites move up and down all the time, but this seems to be across the board.
