Regarding the benefits of including the keywords in the URL, does it make a difference if they're split by forward slashes or by dashes/underscores? For instance, are these any different for the SE's? http://www.example.com/phones/nokia/unlocked/6288 or http://www.example.com/phones-nokia-unlocked-6288 Thanks!
Slashes may indicate that the page is in a folder. That would results to making that page too deep to get crawled by the bots. On the other hand, dashes just means that it is a single page, and that the keyword with dashes on it is just a filename format. So it is a way lot better to use dashes instead of slashes and underscore.
