Let's say I sell a variety of coffee mugs. I have red ones, blue ones, green ones, etc.
Currently, I have one product called "Red Coffee Mug" whose description is "Get a beautiful red coffee mug" and a "Green Coffee Mug" whose description is "Get a beautiful green coffee mug". Obviously, with repeating myself... it's the same thing with every color. :)
Would it smarter for me to simply have a "Coffee Mug" product with an option to choose colors and maybe a description that says, "Our coffee mug is available in green, blue..." than to have individual products for each colored mug?
Let's say I did this because I discovered that "Green Coffee Mug" was a popular keyword and so wanting to rank for it, I made it it's own product assuming that mysite.com/green-coffee-mug.html would rank better for "Green Coffee Mug" than mysite.com/coffee-mug.html.
Even though these descriptions are very vague, often it is difficult to find 10x ways (assuming you have 10 colors) to describe something as boring as mug. :)
Assuming this was my setup, is it safe to assume that this duplicate content is hurting me?
