About

The page title is the most important navigation aid, as it confirms to site visitors where they are within the site. The page title appears in the title bar (top left) of a browser. When meaningful, this information can be used to enhance the navigation of the site and assist in understanding the website structure, just as a breadcrumb trail.

If no page title is defined, the full web address or a default name assigned by the page authoring software, such as "Untitled" will appear in the title bar. The person using the speech or Braille software will hear the title of the page first.
