Links are important for all users and should be constructed properly whether you are aiming for Accessibility or not.
Links should be provided with text that identifies the purpose of the link. This is a good guideline not only for Accessibility but for search engine optimization. Your site visitor should be able to determine where the link will take them or what it will do without clicking on it. Some Assistive Technologies provide users with a list of all links on a page. A link that reads “click here” will not give them any useful information when taken out of context this way.
Links to the same destination should also have the same description. This is a requirement for a good interface because it gives predictability but it is frequently ignored by search engine optimizers who pepper pages with keyword links all leading to the same place. Don’t do this.
Sometimes it will not be possible to include the full context within the link.
The guidelines do provide an exception for links where the purpose of the link cannot be determined from the information on the page. In our view, there is no good reason to have a link that has no context on the page. The example given by the W3C is as follows:
Example: The word guava in the following sentence "One of the notable exports is guava" is a link. The link could lead to a definition of guava, a chart listing the quantity of guava exported or a photograph of people harvesting guava. Until the link is activated, all readers are unsure and the person with a disability is not at any disadvantage.
In our opinion, all users would be better served by simply re-wording the content: “One of the notable exports is guava. Learn more about guava exports.”
SiteCM supports the creation of a title attribute on a link however this is not a suitable solution for accessibility because of poor support browsers and Adaptive Technologies.
