Finally after so much of discussion in forums and webmaster’s thread, 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 update was Panda 23 on December 21, 2012 and it impacted 1.3% of English queries . 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.
Last week there were many threads in forums regarding algorithm update, which Google denied.
