Hi, We are redoing our site structure and I was wondering what are the benefits of having a flat url structure. For example store.com/product instead of doing store.com/category/product. I noticed sites doing it both ways, even moz.com has both structures ex: moz.com/learn/seo and when you clck on something it brings you to moz.com/seo-expert-quiz (even though following the previous logic it should be moz.com/learn/seo/seo-expert-quiz) Please advise, Thanks!
