The Google Panda Timeline: 22 Dates To Remember

One of the common misconceptions about Google Panda was that it was just 1 or 2 major updates.

That has hardly been the case. Instead Panda has been a well thought out, well executed, and highly patient process of multiple roll-outs over the past 2 years. Here are the 22 Google Panda updates that took place from January 2011 to December 2012 in chronological order.

• 1. February 23, 2011: The Original Panda Update - Google's attempt to stop scrapers and according to Matt Cutts, this update affected roughly 2% of all queries.
   
• 2. April 11, 2011: Panda 2.0 - This update by Google rolled out Panda to all English search queries worldwide.
   
• 3. May 9, 2011: Panda 2.1 - Minor changes.
   
• 4. June 21, 2011: Panda 2.2 - Really just a continuation from past Panda updates.
   
• 5. July 23, 2011: Panda 2.3 - Details were never really disclosed about this update.
   
• 6. August 12, 2011: Panda 2.4 - Google rolls out Panda to international non-english speaking queries with the exception of Chinese, Japanese, and Korean.
   
• 7. September 28, 2011: Panda 2.5 - Details were also never disclosed here. But many large sites received huge hits from this update.
   
• 8. November 18, 2011: Panda 3.1 - After many updates of what Google dubbed "Panda Flux Updates," this update was released.
   
• 9. January 18, 2012: Panda 3.2 - More changes with no real algorithm updates.
   
• 10. February 27, 2012: Panda 3.3 - Another type of "flux" update.
   
• 11. March 23, 2012: Panda 3.4 - This update impacted an estimated 1.4% of search results.
   
• 12. April 19, 2012: Panda 3.5 - Yet another routine minimal impact update by Google.
