Google PENGUIN Algorithm

Google launched the Penguin Update in April 2012

 

Google Penguin is a code name for a Google algorithm update that was first announced on April 24, 2012. The update is aimed at decreasing search engine rankings of websites that violate Google’s Webmaster Guidelines by using now declared black-hat SEO techniques involved in increasing artificially the ranking of a webpage by manipulating the number of links pointing to the page.

Google PENGUIN release was to better catch sites deemed to be spamming its search results, in particular those doing so by buying links or obtaining them through link networks designed primarily to boost Google rankings. When a new Penguin Update is released, sites that have taken action to remove bad links (such as through the Google disavow links tool or to remove spam may regain rankings).

Global Impact of Google Penguin :

 Penguin affects approximately 3.1% of search queries in English, about 3% of queries in languages like German, Chinese, and Arabic, and an even bigger percentage of them in "highly spammed" languages. 

Two days after Penguin update was released Google prepared a feedback form, designed for two categories of users: 

1. Those who want to report web spam that still ranks highly after the search algorithm change, and

2. Those who think that their site got unfairly hit by the update. Google also has a reconsideration form through Google Webmaster Tools for the 700,000 sites.

Conclusion :

New sites not previously caught might get trapped by Penguin. “False positives,” sites that were caught by mistake, may escape.

There will be frequent updates to this innovative PENGUIN Algorithm by Google.
