Applicability

This rule applies to any set of any two or more HTML or SVG elements for which all the following are true:

• the elements are inheriting semantic link nodes; and
• the elements are in the same web page (HTML); and
• the elements are included in an accessibility tree; and
• the elements have matching accessible names that are not empty ("").

Note: The test target for this rule is the full set of link elements that share the same matching accessible name.

Expectation

When followed, the links in each set of target elements resolve to the same resource or to equivalent resources. Resolving the links includes potential redirects, if the redirects happen instantly.

Assumptions

• This rule assumes that the purpose of the links with identical accessible names would not be ambiguous to users in general when seen in context on the web page, which is the exception mentioned in Success Criterion 2.4.9 Link Purpose (Link Only). If the links are ambiguous to users in general, users of assistive technologies are not at a disadvantage when viewing the links out of context, e.g. on a list of links in a screen reader, which makes it more of a general user experience concern than an accessibility issue.
• This rule assumes that, within the context of the test subject, the description provided by the accessible name of a link can only accurately describe one resource (notably, homonyms alone are not used as link names). Thus, if two or more links have the same accessible name but resolve to different resources, at least one of them does not describe its purpose.
• This rule assumes that the language of each test target can be correctly determined (either programmatically or by analyzing the content), and sufficiently understood.
