I see no reason why PDF couldn't be considered duplicate content but I haven't seen any threads about it. We publish loads of product documentation provided by manufacturers as well as White Papers and Case Studies. These give our customers and prospects a better idea off our solutions and help them along their buying process. However, I'm not sure if it would be better to make them non-indexable to prevent duplicate content issues. Clearly we would prefer a solutions where we benefit from to keywords in the documents. Any one has insight on how to deal with PDF provided by third parties? Thanks in advance.
