Penguin 4, the fourth and newest release of Google’s Penguin Update is now live.  Penguin 4 actually contains a technology from an older update, Penguin 2.0.  Google stated that this is a new generation of tech that should help better stop spam.  Matt Cutts, who heads the web spam team at Google, had announced the Penguin 2.0 update during episode #19 of This Week In Google.

Matt said that 2.03% of English queries will be impacted noticeably by the newest update.  So, Webmasters and SEOs, you may want to take note on this.

More details were posted on Cutts’ blog about the new update.  According to the blog, it says that the launch is complete, which includes languages other than English.  He also said that “the scope of Penguin varies by language, e.g. languages with more webspam will see more impact.”

You want to know what has happened so far with all of the Penguin updates in sequential order?  Here’s a list of all of the updates to date.

  • Penguin 1 on April 24, 2012 (impacting ~3.1% of queries)
  • Penguin 2 on May 26, 2012 (impacting less than 0.1%)
  • Penguin 3 on October 5, 2012 (impacting ~0.3% of queries)
  • Penguin 4 on May 22, 2013 (impacting 2.3% of queries)

Despite the updates one and two, which contained minor updates, this new update is a pretty major one.  Because the changes are so big, Google has called it Penguin 2.0.  The update will go deeper than the first Penguin update, and in turn, impact more SEOs and webmasters than the first generation version.
