Building out my first Amazon Affiliate site, and have two question on how Google treats duplicate content. Let's say I have a review for a single product (Rayband Sunglasses) and that product has both an individual review page, and is also included in the 'Best of Sports Sunglasses' page. Can I use the same content within both pages, or will that been seen as duplicate content. For example, my 'Best of Sports Sunglasses' has 5 products, and each product has at least a 600 word description, so it seems a bit of a waste to have to re-write each individual review for their own pages. Wonder if I can just copy over the content. Second, what happens if a single product fits in two different 'Best of X' pages. For instance I have a 'Best Rayband Sunglasses' and 'Best Sports Sunglasses' and the Rayband XR-4 are included in both pages. Should I have a unique write up for XR in each 'Best Of' page or can I copy/paste. Appreciate any thoughts or input.
