Google has released 5th Penguin 2.1 update on 4th october

Matt Cutts, Head of web spam team at Google, tweet on twitter that latest release would impact about 1 % of all searches.

It means everyone is trying to improve their website that’s good for everyone but bad for those who are affected by this update. Before Penguin 2.1, Google has introduced another algorithm on his birthday know as Humming Bird. It just shocked all the SEO and webmasters who are not working according to these updates.
