Success Criterion 2.4.4: Link Purpose (In Context)
The purpose of each link can be determined from the link text alone
Technique: Links must not rely on the surrounding text for a meaning, so always use descriptive text on links and linked images. To avoid confusing users, make sure that the link text and the main heading on the target page are the same where possible, or at least contain similar words. Never use ‘click here’, ‘learn more’, or similar phrases as the link text, and avoid URLs as links. Poorly written links make it difficult for the screen reader and the screen magnifier users to navigate the page.
Example from Uni SA:
‘Additional information can be found on the Future Students section of the school website.’
Additional information can be found on the <a href=”http://www.school.edu.au/future/default.asp”>Future Students section of the school website</a>.
