Owing to this, webmasters and SEO are experiencing the recovery from their degraded ranking and lower traffic that they suffered due to previous algorithms.
Previously Google has announced that new Panda algorithm would be implemented over a 10 day period of the month. But they did delay the deployment. Google official Matt Cutts informed that the cause of delay in monthly Panda refresh is they wanted to release the signal that would soften Panda algorithm bit more.
