SEO Fact

Google does not “penalise” duplicate content - it will just show one page over another. If there are 3 pages of duplicate content on your website it generally will only show 1 result on a Google results page, (unless the search is incredibly longtail and specific – but of course we now get the “omitted results” link displayed). Google just shows the content that it feels is most relevant to the users search. New algorithms take into account things like content age (so original content is more likely to rank higher).
