On our eCommerce website we sell products that each have about 20 color variations. When the site was built each color variation was added individually instead as a single product with a configurable color option. Would it be best to combine the different variations into a single product with a configurable drop down menu for color or to leave as is? I am worried the search engines see the individual product pages for each color as duplicate content. What are your thoughts on how Zappos handles color variations? On the category page they display each color variation as an individual product but when the product is clicked it goes to a single product page with the different configurable color variations.
Thanks
