What
By using descriptive link names, you can create a user-friendly website that ranks higher in search results, converts more visitors, and leaves a positive impression on everyone who interacts with it.
A link name is the Aria rule,
Each link’s accessible name should concisely describe its unique purpose.
Why
Link names are really important for screen readers.
An accessible name is a word or phrase coded in a way that assistive technologies can associate it with a specific user interface object.
Assistive technologies can then refer to the object by name, not just by type.
When a link doesn’t have an accessible name, people who use assistive technologies have no way of knowing its purpose.
How
Add an "aria-label" attribute provides an accessible name that describes the link's purpose. Everyone can then know what the link does.
