扫描页面以查找损坏的超链接以及 404/500 错误。

Broken links damage user experience, hurt SEO rankings, and make your site look unmaintained. They accumulate silently over time — pages get renamed, external sites go offline, CDN URLs change, and images get deleted. Broken Link Checker finds them all on any page with a single scan. It collects every URL referenced on the page (anchor href attributes, img src, script src, link href for CSS, and other resource references) and checks each one by making an HTTP HEAD request. The results are categorized by status: 200 OK (working), 301/302 redirects, 404 Not Found (broken), timeout, and connection refused. The summary shows counts for each category. Broken links are listed prominently with their URL, the HTTP status code, and the HTML element that references them. Click any broken link entry to highlight the corresponding element on the page and scroll to it — so you can see exactly where the broken link appears in the page content. Export the full report as CSV or JSON for documentation or bug tracking.

核心功能

Comprehensive Page Scan

Checks every URL on the page: anchor hrefs (internal and external links), image sources, script sources, stylesheet references, favicon, and other resource URLs. Nothing is missed — every reference is tested.

Color-Coded Status Report

Results are color-coded by HTTP status: green (200 OK), blue (301/302 redirects), red (404 Not Found), orange (timeout/connection errors), and gray (skipped/filtered). The summary shows a count for each category.

Click to Locate on Page

Click any link in the report to highlight the HTML element that references it on the page. The page scrolls to the element and it's highlighted with a colored border. Immediately see where the broken link appears in the content.

鞫倩ヲ∫サ溯ョ。謨ー謐ョ

A dashboard at the top shows total links found, how many are OK, how many are broken, how many are redirects, and how many timed out. Get the page's link health at a glance.

蟇シ蜃コ荳コ CSV / JSON

Export the full link report with all URLs, status codes, and source elements. CSV format for spreadsheet analysis, JSON format for programmatic processing. Include in QA reports or hand off to content teams.

Progress Indicator

For pages with many links, a real-time progress bar shows how many links have been checked out of the total. Results appear as they complete — you don't have to wait for the full scan to see initial results.

使用场景

Regular Site Health Checks

Run the checker on your site's key pages periodically to catch newly broken links. External sites go down, internal pages get renamed, and CDN URLs change — catching these early prevents user frustration and SEO damage.

霑∫ァサ蜷守噪體セ謗・螳。隶。

After migrating a site to a new domain, CMS, or URL structure, run the checker on every major page to find links that weren't updated during the migration. Catch broken internal links before users do.

Content QA Before Publishing

Before publishing a new blog post or landing page, run the checker to verify that every link in the content works. Catch typos in URLs, missing anchor targets, and unreachable external references.

SEO 體セ謗・蛛・蠎キ扈エ謚、

Broken links (especially internal 404s) hurt SEO rankings. Google treats them as signals of a poorly maintained site. Regular scans help you maintain a clean link profile.

逶第而螟夜Κ萓晁オ夜。ケ

Check whether external resources (CDN-hosted libraries, third-party images, partner links) are still accessible. External dependencies can break without warning — the checker catches these failures.
