提供您的网站基本网址，此工具将抓取您的网站并报告其在所有页面上找到的所有内部和外部死链接。

在大网站上速度较慢，但至少在我们的测试中，它确实检测到了其他工具未能报告的失效链接。获取结果时，您需要将浏览器停留在该页面上。

In case of a broken link, it will provide the link, your page where the link is located, and the server response type (404, 503 ….)

提示： in our own tests with this tool, we had some false positive “broken” links when the remote site was using a CDN blocking the tool bot. So double-check.

它可与 Google Search Console 或类似工具互补。

Up to 3000 links, there is no registration nor fee required. Just no export of the results in the Free version (but copy/paste…)

学科： 搜索引擎优化、网站开发、内容管理、数字营销、网站管理。

W3C Link Checker 是 Screaming Frog 的免费替代品。

Broken Links Checker compared with Screaming Frog and W3C Link Checker
Broken Links Checker (brokenlinkcheck.com)	Screaming Frog SEO Spider	W3C Link Checker
Method and scope: You give the base URL and it crawls the site, reporting broken internal and external links on all pages it finds. It can be slow on large sites, and the browser must stay open on the page during the run.	Method and scope: A desktop crawler that finds 404 errors and server errors across a site. It also audits many other on-page SEO issues.	Method and scope: It reads an HTML or XHTML document and verifies that links and fragments resolve, that no anchor is defined twice, and warns about redirects. Recursive checking is available with a depth setting.
限制和成本： Up to 3,000 links are checked without registration or fee. The free version has no result export.	限制和成本： The free version crawls up to 500 URLs. The paid licence removes that limit, the maximum then depending on allocated memory and storage.	限制和成本： It is open source under the W3C Software License. By default it waits 1 second between requests to each server, which is also the minimum.
平台和安装： It runs in the browser, so nothing is installed.	平台和安装： It runs on Windows, macOS and Linux.	平台和安装： It is a command-line program or CGI script, installed from CPAN. The listed release is version 5.0.0 of June 2021.
Results and caveats: Each broken link is listed with the page that contains it and the server response, such as 404 or 503. False positives occurred when a remote site used a CDN that blocked the bot, so double-check. It complements Google Search Console.	Results and caveats: Errors can be exported together with their source URLs. Exports can also be scheduled or run from the command line.	Results and caveats: Warnings cover HTTP redirects, including directory redirects. The request timeout defaults to 30 seconds.
