Penguin 2.0 rolled out today


SEO Update: Penguin 2.0 rolled out today

Google started rolling out the next generation of the Penguin webspam algorithm this afternoon (May 22, 2013), and the rollout is now complete. About 2.3% of English-US queries are affected to the degree that a regular user might notice. The change has also finished rolling out for other languages world-wide. The scope of Penguin varies by language, e.g. languages with more webspam will see more impact.

This is the fourth Penguin-related launch Google has done, but because this is an updated algorithm (not just a data refresh), Google has been referring to this change as Penguin 2.0 internally. For more information on what SEOs should expect in the coming months, see the video that they recently released.
