robots.txt
重要な理由
robots.txt controls which parts of a site crawlers may visit. A wrong Disallow rule can block important pages from Google; a missing file is fine but wastes the chance to list your sitemap.
修正方法
- Make sure no Disallow rule blocks pages that should rank.
- Add a “Sitemap:” line pointing to your XML sitemap.
- Test changes before publishing them.
