In Site view, the structure of your site is represented by page icons. As in a family tree, pages have parent, child, and sibling relationships.
In Site view you can add pages to the site, rename pages, move them, copy them, delete them, and complete other site-oriented actions. To add content to a particular page—for example, to add text or pictures—use Page view. As you construct a site, you typically go back and forth between Site view and Page view.
