When a user tabs through a webpage, they often rely on screen readers or other assistive technologies to inform them about the function and purpose of various elements. By employing aria-describedby, developers can enhance the experience for keyboard users by ensuring that these additional instructions are read aloud by the screen reader. This helps clarify the roles of buttons, links, or other interactive components that are not directly focusable.

For instance, tooltips activated on mouse hover do not assist users navigating via keyboard, as they do not typically trigger those interactions. Similarly, audio instructions may not be accessible to all users and can create confusion without proper context. Visual prompts may help some users, but they do not offer the specific auditory guidance necessary for those relying solely on keyboard navigation. Hence, utilizing aria-describedby effectively delivers targeted guidance for users navigating
