Google Penguin is a code name for a Google algorithm renews
that was first announced on April 24, 2012. The renew is aimed at declining
search engine rankings of websites that abuse Google’s Webmaster guiding
principle by using black-hat SEO techniques, such as keyword filling, cloaking,
participating in link schemes, deliberate creation of duplicate content, and
others.
The differences between Penguin and previous updates
Previous to Penguin Google on the rampage a series of
algorithm updates called Panda that first appeared in February 2011. Panda
aimed at down ranking websites that provided pitiable consumer familiarity. To recognize
such websites, a machine-learning algorithm by Navneet Panda was used, hence
the name. The algorithm follows the logic by which Google’s individual superiority
raters determine a website value. In January 2012, purported page layout
algorithm update was released, which beleaguered websites with minute content
above the fold. The calculated goal that Panda, Penguin and page layout update
share is to display superior quality websites at the top of Google search consequences.
However, sites that got down ranked as the outcome of these updates have dissimilar
sets of uniqueness. The main target of Google Penguin update is to check web
spam.
Name of the algorithm
Penguin update went live on April 24, 2012. However, Google
had not come up with an official name for it waiting two days later.
Google Penguin feedback form
Two days after Penguin update was released Google geared up
a response form, planned for two categories of users: those who want to report
web spam that still ranks extremely after the search algorithm change, and
those who think that their site got unfairly hit by the update. Google also has
a re-examination form through Google Webmaster Tools for the 700,000 sites who
received an email stating their sites demonstrated abnormal linking.
Penguin effect on Google search results
Through Google’s estimates, Penguin affects roughly 3.1% of
search queries in English, about 3% of queries in languages like German,
Chinese, and Arabic, and an even larger percentage of them in
"highly-spammed" languages. On May 25th, 2012, Google unveiled the
latest Penguin update, called Penguin 1.1, this Penguin update, according to
Matt Cutts, is believed to crash less than one-tenth of a percent of English
searches.
