“ You’ll note that all this discussion has basically been about nouns—the main things that make up your site, whatever those are (videos, blog posts, books) . There are typically three other types of pages: subpages (which drill down into some aspect of the nouns) , site pages (like about and help and so on) , and verbs (which let you do things with the nouns) . Subpages are some of the easiest, and some of the most difficult. In the easy cases, you just indicate the subpage by adding a slash and a slug for the subpage. ”
