It's no secret that throughout September & October rankings were seeing major fluctuations, which was a prelude to Penguin 4.0. I am still seeing this level of fluctuations on one of my own sites. I can be position 9 on the morning, then 15 a few hours later, then 10, 12 and finish up on 9 across a couple of my main terms. Im seeing competitor domains pop onto page 1 between ranking position 2-4 to then be out of the top 30 later in the day. Is this going to be "the norm" going forward now? Also - in regards to link building post penguin 4.0 - is building manual super web 2.0 and manually writing unique content as tier 1 links and then using GSA for tier 2/3 still a viable option?
