That cuddly Google Panda is back; a new updated version. The updated algorithm is being rolled out this week and is expected to affect 3-5% of queries.
The update targets poor quality website content. For example websites containing thin content could be see their rankings drop.
Looking on the bright side, and for all of our clients, many websites will benefit from having their own unique content, which is meaningful and interesting!
