Documents must have <title> element to aid in navigation

The title element of the HTML document must not be empty in order to give users with an overview of its content.

Users using screen readers utilize page titles to obtain an overview of the page’s content. If a page lacks a title, navigating through it can soon become difficult and confusing for screen reader users. The title element of the page is the first item screen reader users hear when the page loads.

When they arrive at a page, screen reader users hear the page’s title first. If there is no title or if the title is not descriptive and unique, users of screen readers must read the page to discern its content and purpose.

What this Accessibility Rule Checks
