How do I use header tags in my SEO marketing?

Header tags, such as H1, H2, and H3, play an important role in SEO marketing as they help search engines understand the structure and hierarchy of your content. To use header tags effectively, ensure that your main headline uses an H1 tag and that subheadings use H2, H3, and so on, in descending order of importance. 
This helps search engines identify and display your content's key topics and subtopics in search results. Additionally, using relevant keywords in your header tags can help improve your rankings for those specific terms. However, using header tags sparingly and avoiding keyword stuffing is important, as this can negatively impact your SEO efforts.
