# Heading

Heading tags from H1 to H6 in HTML structure the hierarchy of page content for both users and search engines.

**Heading (Heading tags / H1-H6)** is a six-level heading tag used in HTML to structure a page’s content hierarchy.

Hierarchy:

- **H1:** The main heading of the page; there should be only one per page.
- **H2:** Main section headings.
- **H3:** Subsection headings under H2.
- **H4-H6:** Deeper subheadings (rarely needed).

The importance of headings in SEO:

- They communicate the content structure to search engines
- They increase the chances of being selected for a featured snippet
- They provide screen reader navigation for accessibility
- They strengthen the context of keywords

Common mistakes: using multiple H1s, skipping the hierarchy (using H3 when there is no H2), and using headings purely for visual style (CSS should be used for font size instead of H tags).

**Tip:** Create the heading tree (outline) first when planning your content. This structure organizes your writing process and provides a more scannable experience for the reader.
