Google[5] Penguin is a significant update to Google’s motor de busca[2] algorithm[4] designed to penalize websites that use manipulative techniques to achieve high search rankings. Launched in 2012, it specifically targets websites with doorway pages and those not adhering to Google’s guidelines. Google Penguin has seen several updates, the most notable being Penguin 4.0 in 2016, which became part of Google’s core algorithm and operates in real-time. This latest update assesses websites based on individual URL[6] merits and discredits bad links rather than demoting entire websites. Google provides recovery measures for affected websites, including a feedback form, and recommends building good links while removing bad ones for the best results. Google Penguin plays a key role in Google’s broader algorithm updates, along with Google Panda[3], Google Hummingbird[1], RankBrain, and Mobilegeddon.
Google Penguin was a codename for a Google algorithm update that was first announced on April 24, 2012. The update was aimed at decreasing search engine rankings of websites that violate Google's Webmaster Guidelines by using now declared Grey Hat SEM 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, as of 2013, Google announced all updates to the Penguin filter to the public.
