Write descriptive labels for links
When you include links in a document, make sure the label or text for the link accurately describes the link's purpose and the content it leads to. This will help users understand why a specific link was included in a document.
Most assistive technology software provides users with a list of the links in a document, no matter the user's current position in a document. This feature removes links from their original context, which can make it difficult for users to understand why a link might be included. Also, if a link in a document is simply the document's URL, some screen readers may end up reading the URL out letter-by-letter. Using descriptive text for links will avoid this.
When writing descriptive text for links, avoid using common, nondescriptive phrases like "learn more" or "click here", or using only the URL. For example, "For more information, " will sound clearer and more useful to those using screen readers than "For more information on certificate series, ".
If creating a document that is intended for print, as opposed to electronic use, you should provide both descriptive text and the full URL.
