Google on 20th May 2014 officially announced the roll out of
yet another Panda update termed as Panda 4.0. Surprisingly Matt Cutts
personally tweeted about its confirmation in the backdrop of the fact that
very recently Google officially stated that it would not be making any
further confirmation about the Panda. With Google claiming to affect as
much as 7.5% English queries it would not be wrong to assume that we are
sure to witness a wide spread changes in SERP.
