If you are organizing the site structure for an ecommerce site, how would you do it?

[Zookeeper]

Should you use not use slashes and use all dashes or use just a few slashes and the rest with dashes? For example,

domain.com/category/brand/product-color-etc  OR  domain.com/anythinghere-color-dimensions-etc

Which structure would you rather go for and why?

I would go with the first choice, or even something like domain.com/category/product (you could always include the brand in the SEO-friendly URL). The only situation where I would use the second option would be if I had a really tiny site, say 50 products or less. I would do it more from a future-proofing viewpoint than any specific SEO reason. With choice #1, if you ever move or replatform your site, it will be far easier to keep your products organized and to implement any necessary 301-redirects than if you choose options #2. It will also be far easier to sort these URLs in a database and then populate new categories on a new site. I suppose I prefer #1 because it makes managing the data easier, particularly on large sites.
