The latest Google algorthum update has hit websites & search. Learn about how Google Panda Update 4.2 will affect your website's rankings.
Technically, Panda 4.2 is not an update: Google didn't introduce new signals, it just reapplied the same signals on new data.
Over the weekend, Google rolled out Panda 4.2, a refresh of the Panda algorithm that will take months to fully roll out.
Panda 4.2 is all about improving the online user experience – which is why the refresh is an enhancement and not a version update.
It's affected on 2% to 3% of English queries, still it is rolling out.
