Google has put a full stop to the rumours that Friday's reported update was a Penguin update. Kicked off last Friday, webmasters reported consistent ups and downs in the search rankings for their keywords.
During a live webmaster hangout on YouTube, Googler john Mueller replied to a question and said that the Friday update the SEO community is chattering about is not related to the Penguin algorithm. Ruling out the possibility Penguin update, John said that Google regularly updates its algorithms that probably impacts the search results. However, he didn't said anything specific about the update or name the update.
