Hiho, Just wanted to open up a discussion to hear out what works out for you. When it comes to auth sites, you end up having thousands of articles, and you really want to make it as clean and neat as possible. This leads to creating a solid structure that makes sense to both the users and the algorithms; specially when it is ALL about content. In my personal experience, the sites I've got do absolutely great when using /nameofpost/ permalinks style (domain.com/nameofpost/); they are all included within their correspondent subcat, cat and parent categories, but they do not show the categories in the URLs. The reason behind this is simply to make it more memorable for the users, however, I was thinking about the entire structure and I was curious to know if having the sub/cat/parent in the URL would carry a significant positive increase in the site's performance. When I think about it from a purely SEO point of view, it kind of makes sense to include categories in the URLs, but at the same time, the crawlers already have a perfect path to your posts and the categories they are included. What I want to know is, if someone has actually tested both ways, what works better and your explanation about it.
