Hello all!

I have always worked successfully with SEO on E-commerce sites, however we are currently revamping an older site for a client and so I thought I'd turn to the community to ask what the best practices that you guys are experiencing for url structures at the moment.

Obviously we do not wish to create duplicate content and so the big question is, what would you guys do for the very best structure for URLs on an E-commerce site that has products in multiple categories?

Let's imagine we are selling toy cars. I have a sports car for sale, so naturally it can go in the sports cars category and it could also go in to the convertibles category too. What is the best way you have found recently that works and increases rankings, but does not create duplicate content?

Thanks in advance!

Kind Regards,

JDM
