Today, Penguin 2.0 is rolled out to stop web spam. It is considered as the fourth release of penguin update. Google says that it’s a new generation of algorithm.
The head of Google Web spam team, MattCutts announced the release of penguin update in his blog. The earlier penguin update only targeted the site’s home page, but this update goes much deeper and has actually large impact in certain small areas.
MattCutts informed in his blog that the penguin 2.0 is rolled out completely and this web spam algorithm affects 2.3% of English queries. He also added that it also affects non English languages.
“We 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), we’ve 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 we recently released.”
Then he also provided a video to explain more detail about Penguin 2.0 update and what expected changes may happen in SEO in the coming months. Here is that video
