I'm currently redesigning a site that organizes information into categories. Some of these categories contain subcategories (and some of those contain even more subcategories).
I'm trying to decide between the following url structures for the resulting pages:
I'm leaning toward the first because there will be more relevant keywords that may help long tail search traffic, but I can see disadvantages as well... the most specific keywords to that page will be further away from the "front" of the url and a long url is harder to share and type correctly. For whatever it's worth, I don't expect there to be more than 3 levels of nested categories.
Thoughts on which approach to take, or even something completely different?
