Hypertext Links: Use text that makes sense when read out of context.

Checkpoint 13.1 [Priority 2] Clearly identify the target of each link.

Good link text should not be overly general; don't use "click here." Not only is this phrase device-dependent (it implies a pointing device) it says nothing about what is to be found if the link if followed. Instead of "click here", link text should indicate the nature of the link target, as in "more information about sea lions" or "text-only version of this page". Note that for the latter case (and other format- or language-specific documents), content developers are encouraged to use content negotiation instead, so that users who prefer text versions will have them served automatically.

In addition to clear link text, content developers may specify a value of the "title" attribute that clearly and accurately describes the target of the link.

If more than one link on a page shares the same link text, all those links should point to the same resource. Such consistency will help page design as well as accessibility.

If two or more links refer to different targets but share the same link text, distinguish the links by specifying a different value for the "title" attribute of each "A" element.

"Auditory users" -- people who are blind, have difficulty seeing, or who are using devices with small or no displays -- are unable to scan the page quickly with their eyes. To get an overview of a page or to quickly find a link, these users will often tab from one link to the next or review a list of available links on a page.

Thus, for a series of related links, include introductory information in the first link, then distinguishing information in the links that follow. This will provide context information for users reading them in sequence.
