Penguin 4.0 - Google has updated the algorithm
Google has officially announced its latest Penguin-related release, which most of us in the search community are calling “Penguin 4.0.”
The update makes some major changes to how Penguin operates, and if your strategy includes any search engine optimization (SEO), you need to know how this affects you.
Google launched the Penguin Update in April 2012 to better catch sites deemed to be spamming its search results, in particular those doing so by buying links or obtaining them through link networks designed primarily to boost Google rankings.
Penguin 4.0 introduces a handful of significant changes to the Penguin algorithm as a whole. When a new Penguin Update is released, websites that have taken action to remove bad links or to remove spam may regain rankings. New websites not previously caught might get trapped by Penguin.
Google appears to be working on consolidating their algorithms to be more streamlined, faster, more gradual, and less noticeable, and I anticipate this trend will continue over time. More of their new updates will likely work their way into the core, and all their new work will likely be as iterative and non-intrusive as possible. Google has reached a solid foundation for ranking determination, and as a result, volatility will only drive itself lower.
