+`[aria-label]` content should be formatted in the same way you would visual text.
 
-Do not kebab case the words like you would an HTML ID. An `aria-label` is different from `aria-labelledby`.
-An `aria-label` is not an ID, and should be formatted as human-friendly text.
+Keep the following practices in mind:
+
+- Use sentence case.
+- Do not kebab case the words like you would an HTML ID. An `aria-label` is different from `aria-labelledby`. An `aria-label` represents the name of a control, and has the same purpsoe as a visual label would for screen reader users. Therefore, it should be formatted as human-friendly text.
+- Do not use line-break characters like, `
`. An accessible name should be concise to start with.
+- Do not set the `aria-label` to a URL. Instead, use an appropriate name.
