What impact do headings have on web accessibility?

Headings play a critical role in web accessibility by providing a structured framework that enhances navigation and comprehension for all users, particularly for those relying on assistive technologies such as screen readers. By organizing content into a logical hierarchy, headings allow users to easily understand the organization of the information and quickly locate the sections they are interested in.

When headings are used effectively, they help to create a clear and predictable flow of information, which is especially beneficial for users with cognitive disabilities or those who may have difficulty processing large amounts of text. This structured approach allows individuals using keyboard navigation or screen readers to skim through the content, finding relevant headings that guide them toward the information they seek.

Moreover, headings are not merely for visual design; they serve a functional purpose in improving the overall usability and accessibility of web content. Proper use of headings ensures that everyone, regardless of their abilities, can access and engage with the content effectively.
