Why is this important?

Screen reader users rely on headings to understand the structure and organization of a page. Incorrect heading order can confuse screen readers and make it difficult for users to navigate and find the information they need.

How to solve this issue

To fix this, use headings in the correct order, starting with H1 for the main heading and using lower-level headings (H2, H3, etc.) for subheadings. This helps screen readers provide a clear and logical structure to the content.
