HTTP 状态
为何重要
Only pages that return HTTP 200 can be indexed. Error codes (4xx, 5xx) keep the page out of search and tell visitors something is broken.
如何修复
- Make sure the URL returns 200 OK.
- Fix server errors (5xx) in your hosting or application logs.
- For moved pages use a 301 redirect; for removed pages a 404 or 410 is correct.
使用以下工具检查
- Bulk HTTP Status Checker – Check the status code, redirects and response time of up to 25 URLs at once.
- Redirect Checker – Trace every hop of a redirect chain with status codes and timings.
