Google release his last update and give him a name “PENGUIN”. In this update google change his algorithm and target those site which is using duplicate contant , from this update lots of sites got very bad results in google and lots of sites ranking is almost not found, because they are using duplicate contant. They copied good and professional sites contant and published that in his own sites .Professional sites point of view this update is very good because they spend lots of money in his own site and get business from this sites if someone stolen his contant and use in his own site and get good result than the professional site owner got very disappointed and he cant do anything about that, but now if someone do this kind of work than he will be punished by google and his site will be not found in google so professional sites owner is very happy from this update and this update is harmful for those companies and webmasters who use only duplicate contant and not use unique contant.
