What is on-page SEO, and why are header tags important? Header tags (H1, H2, H3, etc.) organize your content, making it easier to read for both users and search engines. These tags define the structure of your page, breaking content into digestible sections and improving user experience. Proper use of header tags in on-page SEO helps search engines understand the hierarchy of your content. Well-structured headings also enhance your SEO by allowing you to incorporate relevant keywords naturally. By optimizing header tags, you provide a clear roadmap for your content, improving both readability and search engine performance.
