Heading tags define the hierarchy of content on a web page for users and search engine bots. H1 is used for the main heading, while H2 through H6 can organize subheadings. The H1 tag should appear only once on a page, while other heading levels may be used multiple times. It is also recommended that the H1 include the target keywords, because search engine bots pay close attention to it alongside the <title> tag.
