H1 見出し
重要な理由
The H1 is the main visible heading of the page. It tells visitors and search engines what the page is about at a glance.
修正方法
- Use exactly one H1 per page that describes its main topic.
- Keep it close to the title tag in meaning, but write it for readers.
- Do not hide the H1 or use it for the logo on every page.
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.
