Using H1, H2, and H3 tags is an excellent way to guide your readers through your content and help them understand your content’s structure and which topics are larger or more important. H1 tags should be used for the main title of your page - Google has confirmed that more than one can be used on a page, however - while H2 tags are used for section headings. H3 tags can be used for subheadings under H2 tags, and so on. By following this hierarchy, you make it easy for both readers and search engines to understand the content's structure.
