Google Panda Holiday Break 14455Google has confirmed rumors of a Google update announcing on Twitter that they pushed out a Panda data refresh today impacting about 1.3% of English queries.

This would make for the 23rd Panda update since the first Panda algorithm was introduced on February 24, 2011. Since then we had 22 updates both to the algorithm and also to the index or data refreshes.

The latest impacted 1.3% of the queries, whereas version 22 impacted only 0.8% of English queries.

We did see signs of a major update a week ago but Google told us there was no such update. Then again, I reported early signs of another update at the Search Engine Roundtable and Google confirmed it on Twitter.

Honestly, I am surprised they released a data refresh right before Christmas. Last year Google promised they would not update the Panda algorithm or do data refreshes until after the holidays – this year, I guess they decided not to wait.

Here are all the releases so far for Panda:

  1. Panda Update 1, Feb. 24, 2011 (11.8% of queries; announced; English in US only)
