Why heading structure matters for AI search

1

AI engines use headings to understand topics

When ChatGPT, Perplexity, or Google AI Overview crawls your page, headings are the primary signal for understanding what each section covers. A clean H1 > H2 > H3 hierarchy tells AI exactly how your topics relate.

2

Question headings match user queries

People ask AI engines questions. When your H2 or H3 is phrased as that exact question — like "What is AEO?" or "How does schema markup help?" — AI can match the heading directly to the query and cite the content underneath.

3

Skipped levels break the content map

Jumping from H1 to H3 (skipping H2) breaks the logical hierarchy that AI depends on. It is like having chapter 1 jump straight to section 1.1.1 — the AI loses context about the parent topic. Always follow proper nesting.

4

One H1, many H2s, deeper H3s

Your page should have exactly one H1 (the page title/topic). Use H2s for major sections and H3s for sub-sections. This creates a table-of-contents structure that AI engines can navigate to find the most relevant section.

Headings are just one piece of AEO

Clean heading structure improves how AI parses your page, but content quality, schema markup, and technical factors also matter. Check your content quality too, or run a full AEO audit for the complete picture.
