页面 SEO
失效链接
为何重要
Links that lead to errors frustrate visitors, waste crawl activity and leak the value that links pass between pages.
如何修复
- Update or remove links that return 404 or 5xx errors.
- Add 301 redirects for pages that moved.
- Re-check links regularly, especially after deleting pages.
使用以下工具检查
- Broken Link Checker – Test every link on a page and find 404s, server errors and redirects.
- Full Site Audit (Crawler) – Crawl a whole website to find broken pages, duplicate titles, missing tags and thin content.
