Why Heading Structure Matters

Proper heading hierarchy helps AI platforms understand your content’s organization, main topics, and relationships between sections. It’s one of the easiest and most impactful on-page SEO improvements you can make.
AI Insight: AI platforms like ChatGPT and Perplexity use heading structure to extract key information and determine what to cite from your content.

​
The Heading Hierarchy

​
H1 - Main Page Title

  • ✅ Only ONE H1 per page
  • ✅ Should match or closely mirror your title tag
  • ✅ Describes the main topic of the page
  • ✅ 20-70 characters optimal
<h1>AI Search Analytics Platform for Marketing Teams</h1>

​
H2 - Main Sections

  • ✅ Multiple H2s allowed
  • ✅ Breaks content into major topics
  • ✅ Should form a logical outline
<h2>Real-time Brand Monitoring</h2>
<h2>Attribution Tracking</h2>
<h2>Citation Analysis</h2>

​
H3 - Subsections

  • ✅ Child topics under H2
  • ✅ Provides additional detail
<h2>Real-time Brand Monitoring</h2>
  <h3>Track ChatGPT Mentions</h3>
  <h3>Monitor Perplexity Results</h3>
  <h3>Analyze Gemini Responses</h3>

​
H4-H6 - Deeper Levels

  • ✅ Use sparingly
  • ✅ For complex, detailed content
  • ✅ Maintain logical hierarchy

Best Practices

Use exactly one H1 tag that describes the page’s main topic:
<!-- Good -->
<h1>Lantern: AI Search Analytics Platform</h1>

<!-- Bad: Multiple H1s -->
<h1>Welcome</h1>
<h1>Our Product</h1>
<h1>Get Started</h1>
Maintain hierarchical order (don’t jump from H2 to H4):
<!-- Good -->
<h2>Main Topic</h2>
  <h3>Subtopic</h3>
    <h4>Detail</h4>

<!-- Bad: Skipping H3 -->
<h2>Main Topic</h2>
  <h4>Detail</h4>
Make headings clear and descriptive:
<!-- Good -->
<h2>How to Track Brand Mentions in ChatGPT</h2>

<!-- Bad -->
<h2>Introduction</h2>
<h2>Next Steps</h2>
<h2>Learn More</h2>
Use target keywords in headings when natural:
<!-- Good -->
<h1>AI Search Analytics: Track Brand Visibility Across AI Platforms</h1>
<h2>Monitor ChatGPT and Perplexity Brand Mentions</h2>

<!-- Bad: Keyword stuffing -->
<h1>AI Search Analytics AI Search Tool AI Platform AI Tracking</h1>
Never use headings just to make text bigger:
<!-- Bad: Using H3 for styling -->
<h3>Click here for more info</h3>

<!-- Good: Use CSS for styling -->
<p class="large-text">Click here for more info</p>
