ABOUT PENGUIN 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. Such tactics are commonly described as link schemes. According to Google's John Mueller, Google has announced all updates to the Penguin filter to the public. A Google representative has confirmed what has been the subject of much speculation over the weekend — a Penguin 3.0 update was rolled out on Friday. This marks the first update to the Penguin algorithm in over a year. On October 9th at Pubcon Las Vegas, Bruce Clay stated during one of his sessions on link building that sources led him to believe that a Penguin update would be coming within the next 10 days. Less than 10 days later a Penguin update was rolled out, so how’s that for a prediction! Google hasn’t yet given more details on the percentage of search results the latest version of Penguin has impacted or if there were any major changes made to it since the last release.
