Link Purpose (Link Only)

Understanding WCAG2.0

The link letters alone must be able to understand the purpose of the link. The difference from 2.4.4 is that it does not allow context dependence. Representing the example of "book" in 2.4.4, HTML version, PDF version, MP3 version must have book name in link letters respectively. However, if "the purpose of the link is ambiguous for most users", it does not seem to be limited to this, but the example of "guava" seems to be difficult for users without disabilities. The door example of "Understanding Success Criterion 2.4.4" may be easier to understand.

there are often implementations that There is a title and it is linked, a little introduction sentence and "Read more" link to the same place as the title. In this case, "Read more" is not a link that can be understood by itself (by the way it is acceptable in 2.4.4). If you read "Read more" as "Read more about {title}", you can "understand independently", so 2.4.9 is satisfied. However, with a screen reader, reading while skipping to the link on the tab is a bit annoying as it reads similar functions in succession. In this case, you can use aria-hidden="true" or tabindex="-1" etc. in this case "Read more" (or "Read more about {title}") If you do, the number of tab key presses will be reduced, making comfortable use in the audio environment. By the way, in 3-2-4a, it is required that "components having the same function can be consistently identified". For example, it is forbidden that the link to the inquiry form of the site is "Contact" or "Contact Us page" and it is not unified (In other words, it is said to be consistent in "Contact" or "Contact Us page"). As in Section 2.4.9, it is considered that understanding the purpose of the link is not disturbing, but even if the character string of the link can be understood, different notation makes the user uneasy You may need to be conscious of it being there.

Principle Operable User interface components and navigation must be operable.
Guideline Navigable Provide ways to help users navigate, find content, and determine where they are.
Criterion Link Purpose (Link Only)
(2.4.9 AAA)
A mechanism that can specify the purpose of each link with the text of the link alone can be used. However, excluding cases where the purpose of the link is ambiguous to most users.
