Google[3] Penguin, a substantial upgrade to Google’s search engine algorithme[4], was launched in 2012 to penalize sites using deceptive practices to obtain high search rankings. It specifically targets sites with doorway pages and those not complying with Google’s guidelines. Google Penguin has undergone several updates, with Penguin 4.0 in 2016 being the most significant, as it became a part of Google’s core algorithm and functions in real-time. This recent update evaluates websites on the merits of individual URLs and disregards poor links instead of downgrading whole websites. To aid affected websites, Google offers recovery measures, such as a feedback form, and advises on building beneficial links while eliminating harmful ones for optimal results. Alongside Google Panda[2], Google Hummingbird[1], RankBrain, and Mobilegeddon, Google Penguin is a crucial component of Google’s wider algorithm updates.
