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. Below is an example of a link that is difficult to read:
Instead consider using concise, readable text to create a useful description of the link:
To create a link, highlight the label, right-click and select Link, or highlight the link and use the Ctrl + K keyboard shortcut. Paste the URL in the address field and click OK.
Avoid using uninformative phrases like "Click Here". Screen reader users may not be able to interpret the URL with insufficient descriptions.
