Penguin Update is an update to the algorithm used by Google to determine the ranking of the web page to display against the search query entered by the searcher.
It is an algorithm to lower the search ranking of sites that are running web spam that violates Google Webmaster Guidelines.
First penguin update was done in April 2012 and like panda update, it is an update that has made publishers frightening every time they announce, but since September 2016 it has been incorporated into regular updates of Google and no announcement of implementation is done.
Therefore, Google updated the algorithm so that websites that would be of high value to search users are displayed.
