Reflections of the fight
against the engine poor quality sites that invade its results, updates Google
Panda and Google Penguin days have marked Search Engine Optimization in 2011 and 2012.
Deployed overseas for the
first time in late February 2011, Google Panda was originally described as an
update to penalize content farms. If the algorithm was indeed poor quality
sites, it has proved much more complex, other players who could suffer as price
comparison sites such. E-commerce, however, did not appear to be particularly
targeted.
A list of official matters
can know if a site can feel targeted by Google Panda, or at least to know the
practices qu'aimerait punish Google with its algorithm. The content, duplicated
or stuffed with spelling mistakes for example, appears to be crucial, but other
criteria may also enter into play. Google does not obviously reveal all.
Today, however SEOs know
that Google Panda is actually a filter with the engine "refresh" the
data and deploys regularly, possibly allowing penalized sites to lift their
sanctions.
After being
"tested" and strengthened the United States, Google Panda was first
shaken the European web extending the English versions of the engine before
being deployed in France on August 11, in the middle of summer holidays summer
and just before the long weekend of August 15 ...
The frequency of deployments
filter was then varied and appears to have accelerated between 2011 and 2012,
although the extent of the damage seems a bit lost in intensity with time.
Thus, in 2011 counted nine deployments of Google Panda, only four in France , although some of these updates have had
severe impacts in France
Mid-March 2013, Matt Cutts
announced that Google Panda would now be integrated into the ongoing updates of
the algorithm. The filter will no longer be deployed manually, and Google will
not be able to confirm the official date for Deployment.
