Links should have meaningful labels to describe their context, purpose, or destination. When URLs are long and have complex syntax structures, screen reader users may have difficulty reading and understanding these links.
Use concise, readable text to create a useful description of the link. Below is a screenshot of a hyperlink with poor readability that you should avoid.
The accessibility of this link can be improved by replacing the URL with a more reader friendly description.
To create a link, highlight the label, right-click and select Link, or highlight the link and use the Ctrl + K keyboard shortcut.
