Web Accessibility: Text Links
Clearly Indicate Text Links
Make a hypertext link informative when read out of context, whether it is on its own or as part of a sequence of links. For example, rather than using the word "more", use full descriptions like "more about career information" or "full text of the report". Make link text succinct.
Avoid using "click here" as clicking refers to using the mouse, which is not possible for everyone, and it is meaningless when read out of context.
Do not use the same link phrase to describe links that point to different URLs. Same link text should point to the same resource.
Use the TITLE attribute to provide more information about links.
