| penguin algorithm | A document classifier developed by Google in 2012 to identify Websites that violate Googles quality guidelines either through keyword-stuffing (q.v.) or outbound manipulative links pointing to other Websites. So-named to avoid associating the algorithm with any specific Google engineer. The Penguin algorithm has been compared to the Panda algorithm (q.v.) and some people believe that Penguin may have been adapted from Panda primarily by using a different type of learning set. You would never know if your Website was affected by the Penguin algorithm but sites depending on links from large numbers of sites affected by Penguin would lose their search referral traffic. |
