Version: WCAG 2.0 and up
Number: 2.4.9
Level: AAA
Applicability:
  • Links
Requirement:

A mechanism is available to allow the purpose of each link to be identified from link text alone, except where the purpose of the link would be ambiguous to users in general.

Purpose

The purpose of this success criterion is to ensure that readers can determine the destination of a link from the text of the link alone (i.e., excluding the surrounding context as allowed in success criterion 2.4.4).

Assistive technologies typically provide access to a list of all the links in a document, for example, so ensuring the link text alone describes the destination optimizes the use of this list.

How to Meet

Authors need to ensure that the text inside the link element describes the destination. In most cases, this is as simple as providing the chapter the link goes to or information about the topic covered at the destination for internal links or providing the site or page name for external links.
