見出し構造
重要な理由
Headings (H2–H6) give a page its outline. A logical structure helps readers scan, helps screen readers navigate and helps search engines and AI tools extract sections.
修正方法
- Use H2 for main sections and H3 for sub-sections – do not skip levels.
- Make headings descriptive instead of decorative.
- Do not use heading tags just for styling; use CSS instead.
次のツールで確認
- Heading Structure Checker – See the H1–H6 outline of any page and spot missing or skipped headings.
