Google has undertaken its 23rd Panda update since the algorithm was introduced in Feb 2012, affecting 1.3% of all user queries.
The update will come as a shock for many just before Christmas, but signals Google’s determination to ensure that it delivers quality search engine results pages.
Earlier in the week some of our clients experienced positive signals, as keyword rankings improved by as much as 25 places. This was timely, as we have conducted extensive work on one particular website, this included: link pruning and the use of the Disavow tool, introducing Google+, Google authorship, and making sure the site carries quality unique content.
