One of the key features of pages is the ability to build information hierarchies. It’s called “nesting”, and it means that content is associated with content at other levels of what can be thought of as a site outline. This practice not only creates a site outline/map that is useful to search engines, but in WordPress it also builds the default navigation menus.

An example of this can be seen on this site. Below is a screenshot of the child pages of “Managing Your Site.”

How the hierarchal parent/child relationship works to organize pages.
Rules of thumb for building successful content relationships:
  1. A parent page can have multiple children, but a child page can only have one parent.
  2. There are no limits to the number of pages you can have, or the depth to which you can nest your content. However, be aware of the best way to organize your site such that users can find and understand how and why things are related.
