When a sighted person visits a page on your website, they view the page at a glance, they can quickly identify the header and footer, the main content area and the navigation. Someone who is blind and who uses a screen reader cannot do this.
Every page on a website should include landmarks. Just like landmarks on a map, landmarks on webpages are recognisable features used for navigation.
The landmarks on the webpage should match the visible features of each page - the header, the main content area, the navigation, the footer and search area, plus any other important “landmark” features.
How does this help screen reader users?
Screen readers recognise these landmarks and provide those who use screen reading software a way to locate items on a webpage easily without having to wade through information on the web pages header etc.
