Readers should be able to determine the purpose of links either from the link text (the words enclosed by the anchor tag) or the link context (generally the same sentence, preferably preceding the link or enclosing element). Descriptive link text helps all users decide whether they wish to follow the link. All links that go to the same location should use the same link text.
2.4.4 Link Purpose (In Context): The purpose of each link can be determined from the link text alone or from the link text together with its programmatically determined link context, except where the purpose of the link would be ambiguous to users in general. (Level A)
How to fix:
- Word your content in such a way that the link text describes the destination of the link.
- Provide context for the link in the preceding text.
- Make sure all links to the same destination use the same link text.
- You can enhance the descriptiveness of the link by adding a descriptive title attribute. (this is not an alternative to making the link text itself descriptive.)
