The Google Penguin update came into effect in 2012 and was dedicated to overly optimized websites. The Google Penguin Update affected 1% of all search queries in the USA after the last update in October 2014. Since 2016, Google Penguin update is part of the core algorithm and thus takes place in real time. The extension is intended to prevent manipulation of results. Google Penguin Update lowers overpimped websites in the rankings or even removes them completely from the search index.
