Use consistent navigation and orientation

Consistency in the interface and information design means people can learn how to use your site and apply what they know across all the pages of your site. Inconsistency in approach can be particularly disruptive for people who use assistive technology, such as screen reader or screen magnification software.

If you provide a useful navigation aid on more than one page, make sure it’s consistently presented in appearance and position each time you use it. When using platforms like Canvas and OpenScholar, much of the interface is provided by the platform. That said, the information design of page’s content also supports wayfinding.

  • Use descriptive page titles. When you create a new page, think about how the page title will appear in the browser history or bookmarks. Provide a title that clearly communicates the purpose and content of the page.
  • Use headings consistently. If you start a convention of preceding the first paragraph on each page with a Level 2 section heading, make sure you always do this.
  • Provide consistent navigation. If you provide a list of items on more than one page, such as a list of links, make sure that the list is consistently ordered on each page.

Testing

  • Review each page you produce. Are you consistent in the way you use headings and navigation options?
  • Do your pages have a descriptive title? Check how they appear in your browser history. One convention is to use Page Name | Section Name | Site Name.

✎ Technique: Writing document titles

The title of a web page is the page's accessible name, and it will be the first thing read aloud by a screen reader when it starts reading the page. It will also be used by search engines, and it labels the browser’s tab containing the page.

To be as helpful as possible, the title should briefly tell the user what the page is about and where they are within the site. 

Examples

Good example

A page containing this content on Harvard's web accessibility site might be described like this:

<title>Writing document titles | Harvard Online Accessibility</title>

This <title> element should be placed in the document's <head> section. When a screen reader loads the document, the title will be the first thing they hear, naming and describing the current page.

PDF example

PDF documents can also be opened in browser tabs, just like HTML pages. Providing a title for a PDF document involves editing its meta information, like so:

  • Select File > Properties
  • Select the Description tab
  • Modify the Title field

Bad example

The <title> element should not be empty or absent—the browser will likely give the page an unhelpful title of "Untitled document."

The title should be plain text, and it shouldn’t contain any HTML markup because the markup will not be parsed and it will appear as garbled text to end users in their browser tab and window labels.


<!-- avoid this -->
<title><strong>Writing document titles</strong> | Harvard Online Accessibility</title>

Note: If you are entering content using a CMS system, the <title> content is usually added automatically, based on the text you enter in the “title” field of your post. It will usually appear as both the main heading of the page (<h1>) and a subset of the <title> content. So writing a good <title> comes down to entering a good description in the page title field.
