A heading on a web page serves as the title for the page and its individual sections, providing structure and hierarchy to the content. The primary page title is designated as an H1 heading, which is typically the most prominent and is used to convey the main topic or purpose of the page. Subsequent headings are categorized as H2, H3, and so on, with each level representing sub-sections that fall under the previous heading’s category. This hierarchical structure helps both users and search engines understand the organization of the content, making it easier to navigate and improving readability. Proper use of headings also enhances SEO by allowing search engines to better index and rank the content based on its relevance and structure.
