Google Update 27th Jan 2011

Matt Cutts announced that last week Google made a change to the algorithm focused specifically on tacking their issue with web spam. You can read more here however in true to Matt Cutts fashion the statement can be read in multiple ways.

Apart from tacking wholesale duplicate content Matt states…

…and sites with low levels of original content.

Does this mean sites that have a lot of duplicate content on them or sites that have a small amount of original content per page?

..I’m confused already.
