I am building a BigCommerce store for selling framed art.  Many of the pieces of art will fall in more than one product category. Let's say I have a framed print of a photograph of a western landscape.  This piece of art would fit into these categories;  "western", "landscape", and "photography".   I would have three pages with duplicate content for just this one framed print. Will google give me less page rank due to this?  Can all the link juice be given to just one of the three categories by use of rel=canonical?  If so, does anyone know how to do this for a bigcommerce site? I would appreciate any feedback. Thanks, Kelly
