The Hosted documentation does not cover this aspect from informational point of view but it is important for you to know how to create a single page or a multi-page website.

Assigning a single web page on Hosted service is a matter of one click, but for multi-page website structure you’ll need different URL paths.
We call them directories because they differ from the main root URL
This are some examples of URLs and description

Subdomain
https://dan.camgirl.cloud/
– the root of this subdomain

Subdomain with blog category
https://dan.camgirl.cloud/blog/
– root subdomain followed by blog directory (or category as showed in Assign Urls to Host Pages window)

Subdomain with blog category and article
https://dan.camgirl.cloud/blog/article-name
– root subdomain followed by blog directory and article name

Now you can create different structure for your website like blog or product directories and assign different web pages to them
https://dan.camgirl.cloud/blog/article-name-1
https://dan.camgirl.cloud/product/product-name-1
https://dan.camgirl.cloud/product/product-name-2
https://dan.camgirl.cloud/product/product-name-3

Make sure that all those pages are linked.
Root subdomain hosted page should have links to both /blog/ and /product/ categories and vice versa
