# Using aria-label for link purpose

ID: ARIA8

Technology: aria

Type: Technique

## When to Use

Technologies that support Accessible Rich Internet Applications (WAI-ARIA).

## Description

The objective of this technique is to describe the purpose of a link using the `aria-label` attribute. The `aria-label` attribute provides a way to place a descriptive text label on an object, such as a link, when there are no elements visible on the page that describe the object. If descriptive elements are visible on the page, the `aria-labelledby` attribute should be used instead of `aria-label`. Providing a descriptive text label lets a user distinguish the link from links in the Web page that lead to other destinations and helps the user determine whether to follow the link. In some assistive technologies the `aria-label` value will show in the list of links instead of the actual link text.

Per the Accessible Name and Description Computation and the Accessible Name and Description Computation in the HTML Accessibility API Mappings 1.0, the `aria-label` text will override the text supplied within the link. As such the text supplied will be used instead of the link text by assistive technology. Due to this it is recommended to start the text used in `aria-label` with the text used within the link. This will allow consistent communication between users.

## Examples

### Describing the purpose of a link in HTML using aria-label.

In some situations, designers may choose to lessen the visual appearance of links on a page by using shorter, repeated link text such as "read more". These situations provide a good use case for aria-label in that the simpler, non-descriptive "read more" text on the page can be replaced with a more descriptive label of the link. The words 'read more' are repeated in the aria-label (which replaces the original anchor text of "[Read more...]") to allow consistent communication between users.
