Google has officially announced via Twitter that they rolled out another Panda update. Webmasters closely following the updates differ in labeling every time a new Panda “version” comes out. As far as we are concerned, Google made no specific mentions of labels to their panda outings. We are calling this Panda Update #16 – to simply follow the chronology of events and not get lost in version-calling.
Another Google tweet confirms this update.
The 16th update was only a refresh, meaning, Google did not tweak any algorithm signal updates. A refresh can mean that Google reruns the Panda algorithm and capture sites that may have missed the first time updates were implemented.
Not to disregard, because this update reportedly – still – affected 1% of the queries. How very insignificant this may look, Google is driving a point that it is serious on catching violators. Wonder how they do not necessarily make scheduled updates and formal announcements. They tweet things only after they have whipped things up.
