Heading levels, often referred to as heading tags or H tags, are structural elements used in markup languages like HTML to denote the hierarchy of headings within a document. These levels range from H1, representing the most important heading, down to H6, representing the least important. The H1 tag is typically reserved for the main title of a page or document, while subsequent levels (H2, H3, etc.) are used to break down content into logical sections and sub-sections.

The primary purpose of heading levels is to improve document organization and readability for both human users and machines. Visually, they often appear with increasing font sizes and decreasing prominence as the level number increases. For web accessibility, heading levels are crucial. Screen readers use them to allow users to navigate through content efficiently, skipping between sections. Search engines also utilize heading levels to understand the structure and topics covered in a document, which can impact search engine optimization (SEO). Proper use of heading levels creates a clear and navigable outline, enhancing the overall user experience.
