Google Penguin Algorithm

A major Google algorithm that launched in April 2012, it was followed by a series of updates and refreshes. The goal of Penguin was to reduce the visibility of overly-optimized sites, or sites that excessively abused certain spammy tactics (e.g., building low-quality links, keyword stuffing). In 2016, Penguin started running in real-time as a part of Google’s core algorithm.
