失效連結檢查工具

檢查一個頁面上的所有連結，查找失效的狀態碼（4xx、5xx）。每次掃描分析至多 30 個連結。

如何使用本工具

1
Paste the full URL of the page you want to check (for example https://example.com/blog) into the input field.
2
Click Analyze and wait while the server fetches the page and probes each link it finds.
3
Read the two tallies at the top: Checked (how many links were probed) and Broken (how many failed).
4
Scan the per-link list below, where each broken link is highlighted in red with its HTTP status code or error reason.

失效連結會損害使用者體驗和 SEO。搜尋引擎會檢索每一個連結；持續存在的 404 錯誤會浪費檢索預算，並暗示網站已被棄管。本工具會並行檢查一個頁面上的前 30 個連結，並回報任何狀態碼失效的連結。對於全站檢索，請使用 Screaming Frog 或 Sitebulb。

Verifying a new blog post or landing page before publishing, so no outbound reference 404s on launch day.
Spot-checking a high-traffic page after a site migration, where redirects and moved pages often leave dangling links.
Auditing a resources or links roundup page where external sites you cited may have quietly disappeared.
Confirming that internal navigation and footer links still resolve after a CMS template change.
Checking a documentation page for dead links to external API references or download mirrors.
Quickly validating a competitor or client page during an SEO review without installing a desktop crawler.

我應該多久檢查一次？▼

穩定的網站每季一次；外部連結不斷累積的活躍網站每月一次。

指向付費牆內容的連結呢？▼

它們往往會回傳 200（登入頁面）：屬於誤報。需要進行人工核查。
