In a new blog post, Matt Cutts – the head of Google’s Webspam team, confirmed that Penguin 2.0 – the next generation of the Penguin webspam algorithm rollout is now complete (on May 22, 2013).
“About 2.3% of English-US queries are affected to the degree that a regular user might notice, Matt Cutts explains. “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.”
