Google Updates 2006



False Alarm - December 2006

There were stirrings about an update in December, along with some reports of major ranking changes in November, but Google reported no major changes.



Supplemental Update - November 2006

Throughout 2006, Google seemed to make changes to the supplemental index and how filtered pages were treated. They claimed in late 2006 that supplemental was not a penalty (even if it sometimes felt that way).
