9. HTML Headings
Headings are used to define the structure of your content, organizing it into sections with meaningful titles. They play a significant role in SEO and accessibility.
What Are HTML Headings?
HTML provides six levels of headings, from <h1> to <h6>, to help structure the content hierarchically. The <h1> tag represents the most important heading, while <h6> is the least important.
Importance of HTML Headings
Headings help:
- SEO: Search engines use headings to understand the content hierarchy and prioritize key information.
- Accessibility: Screen readers rely on headings to navigate and understand the structure of the page.
- Content Organization: Headings break down the content into digestible chunks, making it easier for users to skim and find relevant information.
Using Headings Correctly
Headings should be used in a hierarchical manner:
<h1>should be used once per page, typically for the main title of the page or section.<h2>to<h6>should be used for subheadings, with<h2>representing the most important subheading and<h6>for the least important.- Avoid skipping heading levels. For example, use
<h2>before<h3>, and so on.
Examples of HTML Headings
Example 1: Using <h1> for the Main Title
Typically, the <h1> tag is used for the main title of the page or section. This helps search engines and screen readers identify the primary topic of the content.
<h1>Welcome to Our Website</h1>
Example 2: Using <h2> and <h3> for Subsections
Headings can be used to divide content into sections, making it more organized and readable. Subsections can use <h2> and <h3> tags for further categorization.

Best Practices for Headings
- Use headings to define the structure of your page. Each page should have only one
<h1>tag, which represents the page's primary topic. - Use
<h2>for major subsections and<h3>,<h4>, etc., for more granular levels of content. - Keep headings concise and descriptive. Avoid using headings for styling purposes only.
Common Mistakes to Avoid
- Skipping heading levels (e.g., jumping from
<h1>to<h4>). - Using headings purely for styling without adding meaningful content.
- Using multiple
<h1>tags on a single page.
