I read that it is best practices that if you have a product that comes in 3 colours to have one URL for the product, and then to have a dropdown with all the colours that it comes in?
For example if I had a shirt that comes in 3 colours, grey, green and blue then you will have to have 1 URL like:
www.example.com/product/1001/brand-shirt instead of:
www.example.com/product/1001/brand-shirt-grey www.example.com/product/1001/brand-shirt-green www.example.com/product/1001/brand-shirt-blue
So now my question is, if you are using the one URL for the product, how do you promote the green shirt? How do you direct a customer to the green shirt? How do you share just the green on Facebook, Twitter, etc?
