I am creating a very large table with about 120 different types of generic, related products on my money. I plan on putting a link in the name to a separate post containing basic information about these products, however, I was wondering if I could just copy and paste information from other sites such as wiki or amazon and use that information on those pages. Would I be penalized for doing something like that? My site still has lots of original content, and I'd be putting links to the source. What do you guys think? also, what if I created a wiki with all those pages linking back to my money site as a type of tier 1? I would think wiki's would be fine to have duplicate content. Hell, what's the general opinion on duplicate content for something like this?
