Matt Cutts: Google Panda Updated Monthly But Slowly Rolled Out
Jun 13, 2013 • 8:52 am
Back in March, Google said they will stop confirming Panda updatesbecause they are now more baked into the index and 
algorithm.
Well, at SMX Advanced, Matt Cutts of Google announced it is still roughly updated monthly (although it has been 6 weeks because they are trying tosoften Panda - note, next Panda update sites should be released) but these updates are rolled out gradually over a 10 day period. (How is that for a run on sentence?)
So, Panda might be pushed out on the 1st of the month but take ten full days to fully roll out everywhere. Then it will happen again roughly a month later. So 1/3rd of the month, Panda is rolling out. I called this at Search Engine Land, the Panda Dance.
Google Panda Update Version #24; 1.2% Of Search Queries Impacted
Google has announced a new Panda refresh, making this version number 24.
This refresh has a noticeable impact 1.2% of English based queries according to Google.
The previous confirmed update was #23 and it impacted 1.3% of English queries on December 21, 2012. Prior to that was a refresh on November 21st that impacted 0.8% of queries. It seems like Google is now rolling out these updates every 4 weeks or so.
