Screen reader users have an advantage over other people when it comes to browsing web pages. The screen reader provides secondary methods to browse properly marked up pages. For instance, they can skip through the headers, lists, forms, and links. This is especially helpful when confronted with the mother of all drop-down topnavs.
Headers should define the content that immediately follows. Think of an essay that you may have written in school. The essay starts off with a title (the h1). The h1 defines what the entire paper is about. You will then define the main sections of your essay with subeaders (h2). If a section has multiple sub-sections, you'd use another header for each section (h3). Continue to increase the header number (h4, h5, h6) as the content becomes more granular. Avoid using headers without appropriate following content.
