The subheadings H2, H3, H4, H5 and H6 are intended to make up the logical content of the document - this is like a table of contents in a large book. The further the subtitle is from the beginning of the page, the smaller the role it plays in the overall structure and the less its role in SEO promotion .

<h1>Main header</h1>
   ...
   <h2>Subheader</h2>
      ...
      <h3>Subheader</h3>
   ...
   <h2>Subheader</h2>
...

Each of the headings can be only one level with the previous one or one point above or below it. We can not allow a gap of more than 1 level with the previous subtitle. And, of course, all subheadings should follow only after H1 already placed above . Otherwise, these elements do not have specific recommendations for completion.

Final checklist for writing subtitles

► Be sure to use H2-H6 subtitles in the text.

► Observe hierarchy and nesting

► Write diluted key queries without exact entries.

► Subheadings must be unique within one page.

Do not use subheadings in product names, menus , etc.

Do not insert nested tags in the subtitle text
