Yesterday we broke the news that there was an other update that overlapped the EMD update that we had on friday targeting exact match domains. I wasn’t sure what that update was, so I emailed our friends at Google and Matt Cutts responded that it was a Panda update that began to roll out on Thursday and has been continuing to roll out even today and will likely finish rolling out through the weekend.
