Penguin Algorithm Update
After much speculation over when Google’s fourth Penguin launch would be released, the company’s webspam team leader announced last week that the next generation of the spam-fighting algorithm hit the web on May 22nd.
In his Matt Cutts: Gadgets, Google, and SEO blog, Cutts said the company had both started and finished rolling out the next generation of the Penguin webspam algorithm. 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 worldwide. The scope of Penguin varies by language, e.g. languages with more webspam will see more impact.
According to Cutts, this is the fourth Penguin-related launch Google has done, but because this is an updated algorithm (not just a data refresh), “we’ve been referring to this change as Penguin 2.0 internally,” he says. “For more information on what SEOs should expect in the coming months, see the video that we recently released.”
Cutts also noted that if there are spam sites that you’d like to report after Penguin, Google has created a special spam report form at http://bit.ly/penguinspamreport.
