What does Heading structure mean?

Heading structure refers to the hierarchical arrangement of headings on a web page using the HTML tags H1 to H6. H1 usually represents the main heading of the page, while H2, H3 and further levels divide the content into smaller thematic sections and subsections. A correct structure helps visitors quickly find their way around the text and also makes it easier for search engines to understand its organization and context. Headings should be factual, clear and follow each other logically according to their meaning, not according to the desired font size. In SEO, they can include relevant keywords, but always naturally and only where they match the actual topic of the section.
