Links are part of the World Wide Web. Browsers used by visually impaired people often allow a navigation from link to link in order to gain time. With this style of navigation, the user reads only the text of the links. Consequently, it is important to use texts that can be understood out of the context (especially links, which are not clearly formulated, should be avoided: like «Click here»). For the same grounds, if links can be found several times in the same document, they should refer to the same URL.
Moreover, Braille displays usually have a length of 40 and often a length of 20 characters. As far as possible, use brief texts for the links. It is also useful to provide keyboard shortcuts («accesskey» attribute) for people who do not use the mouse. Finally, the «title» attribute allows to define a title for each link and to determine the content of the page which is pointed out by this link.
Here are three examples :
Click here and win an orange
This example is very bad because the text of the link gives no indication about the destination.
Click here and win an orange
This example is bad because the text of the link is too long, the beginning brings nothing.
Win an orange
This example is clear, the link indicates precisely and shortly where it points out.
