Checkpoint AA2.4.5: *WCAG 2.0 AA* Multiple Ways

More than one way is available to locate a Web page within a set of Web pages, except where the Web Page is the result of, or a step in, a process.


Rationale

This checkpoint is used to enable users to locate information in a way that best suits their needs. With access to multiple ways of locating information, users may prefer one way over another. For example, a user may prefer a site's search function to locate specific information rather than scrolling through a table of contents. Alternatively, a user who prefers to understand a Web site's structure may find a table of contents or site map more useful.

On the home page of a small Web site, links to other pages may serve as a site map.

Required development and unit test techniques


To comply with this checkpoint, you must meet two or more of the following techniques. These techniques are defined in WCAG 2.0 Level AA Success Criterion 2.4.5 (link resides outside of ibm.com).

  1. Site map: Provide a site map.
  2. Table of contents: Provide a Table of Contents.
  3. Link list: Provide a list of links to all other Web pages.
  4. Related links: Provide links to navigate to related Web pages.
  5. Search: Provide a search function to help users find content.
  6. Home page links: Provide links on the home page to all other pages of the Web site

Note: The examples presented in the techniques are not exhaustive. They are meant to illustrate the spirit of this checkpoint.

General examples

  1. Site map: Provide a site map.

    To comply with technique 1, you must implement the following example.

    General example 1

    The Web Accessibility Initiative's site map (link resides outside of ibm.com) contains links to pages on the site, including introductory information, guidelines and techniques.

    Required unit tests for general development technique 1

    Manually review the page to confirm the following criteria:

    • The user can get to all the corresponding pages using links in the site map.
    • Each target page has a link to get back to the site map.
  2. Table of contents: Provide a Table of Contents.

    To comply with technique 2, you must implement the following example.

    General example 2

    The Web Content Accessibility Guidelines (WCAG) 2.0 (link resides outside of ibm.com) contains a table of contents near the top of the page to help users quickly locate information.

    Required unit tests for general development technique 2

    Manually review the page to confirm the following criteria:

    • The section names and the order of entries in the table of contents correspond to the names and order of the sections of the document.
    • Each entry leads to the correct section in the document.
  3. Link list: Provide a list of links to all other Web pages.

    To comply with technique 3, you must implement the following example.

    General example 3

    A school Web site contains a short biography of each of its instructors. A Web page is dedicated to each instructor and each biography page contains a list of links to all the other biographies.

    Required unit tests for general development technique 3

    Manually review the page to confirm that the site contains a list of links for each of the site's pages and that the links open the appropriate target.

  4. Related links: Provide links to navigate to related Web pages.

    To comply with technique 4, you must implement the following example.

    General example 4

    The Web accessibility checklist contains a set of checkpoints that developers use to assess the compliance status of Web content. Each checkpoint contains a link to related techniques and examples that can be used to implement a checkpoint's requirements.

    Required unit tests for general development technique 4

    Manually review the page to confirm that a list of links is provided for every related Web page in the site and the links take the user to the appropriate target.

  5. Search: Provide a search function to help users find content.

    To comply with technique 5, you must implement the following example.

    General example 5

    The ibm.com site contains hundreds of Web pages. The site provides a search function that enables users to quickly find specific topics of interest.

    Required unit tests for general development technique 5

    Manually review the page to confirm the following criteria:

    • The user can activate the search function with a search term using the keyboard.
    • The user is taken to the appropriate content as a result.
  6. Home page links: Provide links on the home page to all other pages of the Web site.

    To comply with technique 6, you must implement the following example.

    General example 6

    The home page of a department store's Web site contains all the links in the site, including the manager's biographical information, a link to a page about how to return merchandise, and information on the parent company that owns the store.

    Required unit tests for general development technique 6

    Manually review the page to confirm the following criteria:

    • The home page contains links to all other pages in the Web site.
    • The user can get back to the home page from all other pages.

Recommended development techniques

Although you are not required to implement the recommended techniques in order to comply with this checkpoint, you should review these techniques because they can improve the accessibility and usability of the application. Refer to WCAG 2.0 Additional Techniques (Advisory) for Success Criterion 2.4.6 (link resides outside of ibm.com) for a list of techniques and examples.
