I could see a big traffic change for few of my blogs starting form 5th November 2012. Initially I thought it’s a Monday effect as 4th Nov was Weekend, but similarly I could see many bloggers asking in the Webmaster forum about traffic change from 5th November. Today (7th November), Google confirmed about the panda data refresh which affected less than 1.1 English queries.
