Table of Contents

What is a Table of Contents?

A Table of Contents (TOC) or table of contents is a structured overview of the main sections of an article or web page. It serves as a navigation aid for users and search engines to quickly grasp the content and jump to relevant sections.

1. Improved User Experience

• Quick Navigation: Users can jump directly to relevant sections
• Content Overview: Better orientation in long articles
• Reduced Bounce Rate: Users stay longer on the page

2. SEO Benefits

• Structured Data: Better understanding for search engines
• Featured Snippets: Higher chance of snippet awards
• Internal Linking: Improved internal linking structure
• Dwell Time: Longer dwell time on the page

Types of Table of Contents

Best Practices for Table of Contents

1. Structure and Hierarchy

H2 headings as main points:

• Use H2 tags for main sections
• H3 tags for subsections
• Maximum 3-4 levels deep

Logical order:

• Introduction → Main content → Conclusion
• Chronological or thematic arrangement
• Most important points first

2. Technical Implementation

HTML structure:

<nav class="table-of-contents">
  <h2>Table of Contents</h2>
  <ol>
    <li><a href="#introduction">Introduction</a></li>
    <li><a href="#main-content">Main Content</a>
      <ol>
        <li><a href="#sub-point-1">Sub Point 1</a></li>
        <li><a href="#sub-point-2">Sub Point 2</a></li>
      </ol>
    </li>
    <li><a href="#conclusion">Conclusion</a></li>
  </ol>
</nav>

Set jump marks:

• Give each heading a unique ID
• Use kebab-case for IDs (e.g. #keyword-optimization)
• No special characters or spaces

3. Content Optimization

Optimize headings:

• Integrate keywords in headings
• Use clear, descriptive titles
• Maximum 60 characters per heading

Design anchor texts:

• Use descriptive anchor texts
• Integrate keywords naturally
• No generic terms like "click here"
