Your Site Hierarchy is the functional arrangement of pages as displayed in the Site Admin — structured much like a folder/file setup in your OS. Your Site Navigation is the visual arrangement of these pages displayed of your site, as seen by visitors. Site Hierarchy and Navigation are not necessarily the same — initially they mirror each other, but Navigation can be made unique (see "Adjust Pages in Site Navigation" below).
Site Maps are an effective visual tool for organizing content, and the first level of structure that should be established before building sites. They can be as basic or as detailed as you want, and can even be drafted in tools like PowerPoint.
In a perfect world, you'd never need to modify your site hierarchy, but when the inevitable adjustments must be made you'll need to know how to move your pages.
Relocating Pages (change URL/Name)
- Relocate pages using the 'Move' feature. Select a page, and from the toolbar click Move

- The Move Page dialogue is the only way to rename (URL) pages – it also allows you to retitle pages as well, though this is also possible via Page Properties.

- Remember to use all lower case, dashes or underscore to separate words, and definitely don't leave any spaces in the name.
- All rearrangements or property edits need to be activated.
Adjust Pages in Site Navigation
First switch to the List View, then drag pages up or down to place it in the desired order. Note this adjustment can only be done within the current directory. Use the Move function to relocate pages to different hierarchy locations.

Change a page's navigation title to be unique
Within Page Properties, adjust the Navigation Title field. Otherwise, the navigation title mirrors the Page Title.
