Headings Hierarchy: Headings hierarchy refers to the structure and organization of headings and subheadings on a webpage or within a piece of content. It's essential for both SEO and user experience (UX) as it allows search engines to understand the content better, and it enables users to easily navigate and comprehend the content. Headings are typically indicated by HTML tags (such as H1, H2, H3, etc.) with H1 being the main heading, followed by H2 for subheadings, H3 for sub-subheadings and so on. A clear and consistent headings hierarchy improves readability, accessibility, and content organization.
