What it measures

Structure measures how well your page is organized using HTML semantic elements — headings, lists, tables, and structured data markup. It combines DOM Heading Cleanliness (40%), Table/List Density (35%), and JSON-LD Schema (25%).

Why it matters for AI

AI crawlers rely on proper heading hierarchy (H1→H2→H3) to understand your content's outline, and they extract tables and lists as structured data. Good structure makes your content easier for AI to parse, index, and cite specific sections.

How to improve

1. Ensure a clean heading hierarchy — H1→H2→H3 without skips
2. Add structured data (JSON-LD) — Article schema with author, dates, and headline
3. Use tables for comparative data — AI extracts tables into structured answers
4. Include lists for step-by-step content — Ordered lists for processes, unordered for features
