Google Penguin

Google Penguin is a codename[1] 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[2] 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.[3] According to Google's John Mueller, Google has announced all updates to the Penguin filter to the public.[4]

Effect on search results

By Google’s estimates,[5] 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. On May 25, 2012, Google unveiled another Penguin update, called Penguin 1.1. This update, according to Matt Cutts, head of webspam at Google, was supposed to affect less than one-tenth of a percent of English searches. The guiding principle for the update was to penalize websites using manipulative techniques to achieve high rankings. The purpose per Google was to catch excessive spammers. Allegedly, few websites lost search rankings on Google for specific keywords during the Panda and Penguin rollouts. Google specifically mentions that doorway pages, which are only built to attract search engine traffic, are against their webmaster guidelines.

In January 2012, the so-called Page Layout Algorithm Update[6] (also known as the Top Heavy Update)[7] was released, which targeted websites with too many ads, or too little content above the fold.

Penguin 3 was released October 5, 2012 and affected 0.3% of queries.[8] Penguin 4 (AKA Penguin 2.0) was released on May 22, 2013 and affected 2.3% of queries.[9] Penguin 5 (AKA Penguin 2.1)[10] was released on October 4, 2013, affected around 1% of queries, and has been the most recent of the Google Penguin algorithm updates.[11]

Google may have released Penguin 3.0 on October 18, 2014.[12]

On October 21, 2014, Google's Pierre Farr confirmed that Penguin 3.0 was an algorithm "refresh", with no new signals added.[13]

On April 7, 2015, Google's John Mueller said in a Google+ hangout that both Penguin and Panda "currently are not updating the data regularly" and that updates must be pushed out manually. This confirms that the algorithm is not updated continuously which was believed to be the case earlier on in the year.[14]

The strategic goal that Panda, Penguin, and the page layout update share is to display higher quality websites at the top of Google’s search results. However, sites that were downranked as the result of these updates have different sets of characteristics. The main target of Google Penguin is spamdexing (including link bombing).

Google’s Penguin feedback form

Two days after the Penguin update was released Google prepared a feedback form,[15] designed for two categories of users: those who want to report web spam that still ranks highly after the search algorithm change, and those who think that their site got unfairly hit by the update. Google also has a reconsideration form through Google Webmaster Tools.

In January 2015, Google's John Mueller said that a Penguin penalty can be removed by simply building good links. The usual process is to remove bad links manually or by using Google's Disavow tool and then filing a reconsideration request. Mueller elaborated on this by saying the algorithm looks at the percentage of good links versus bad links, so by building more good links it may tip the algorithm in your favor which would lead to recovery.[16]
