SEO Question about URL Slashes in Slugs

Question

I do a lot of development in Codeigniter and Wordpress, but I'm wondering something in terms of SEO when it comes to URL segmentation. Wordpress automatically adds children page slugs onto a parent page. For example:

http://example.com/parent/child/child/

Would it be better for SEO reasons to go with the following?

http://example.com/parent-child-child/

Thanks in advance.

Answer 1

Based on the reports of consultants that we've hired in the past: Yes. According to them lower precedence is placed on each path-part keyword as it's distance from the root increases.

Basically meaning that this:

example.com/my-post-name-that-contains-good-keywords/2011/01/01

is better than:

example.com/2011/01/01/my-post-name-that-contains-good-keywords
