Full-Site Broken Link Crawler

Crawl an unlimited number of web-pages to detect dead links. Test both internal & external URLs, display specific HTTP error codes (404/500/etc.), and pinpoint the exact source code location of bad links.

Why Broken Links Destroy Your SEO Rankings

A broken link (often resulting in a 404 Error code) occurs when a webpage, image, or document that a link points to has been permanently moved or deleted. In the world of Search Engine Optimization, broken links are absolute poison.

When Google crawls your website, its spiders follow links to discover new content. If a spider hits a broken link, it is called a "dead end." Too many dead ends signal to Google that your website is abandoned, poorly maintained, and providing a terrible user experience. Consequently, Google will aggressively downgrade your rankings.

Critical Warning: Broken outbound links (links pointing to other websites) are just as dangerous as broken internal links. If you link to a domain that has expired or been taken over by spam, Google transfers that negative trust score back to your website.

How Our Free Broken Link Checker Works

Our Free Broken Link Checker acts as an automated site auditor. Instead of manually clicking hundreds of links on your webpage, our tool performs a rapid, multi-threaded scan of your DOM architecture.

  • Deep Extraction: We scan the provided URL and instantly extract all <a href> tags, compiling a complete list of your internal and external links.
  • Parallel HTTP Requests: We fire simultaneous HTTP HEAD requests to every single link to verify its live status without downloading the entire page body, making the test lightning fast.
  • Status Code Mapping: We categorize everything. You will see exactly which links return a healthy 200 OK, which ones are bouncing through 301 Redirects, and which ones are fatally crashing with 404 Not Found or 500 Server Error codes.

How to Fix Broken Links After Scanning

Once our auditor finishes scanning your page, repairing the damage is a straightforward three-step process:

  1. Identify the Culprit: Use the "Broken Only" filter on our results table to isolate the failed URLs. Copy the exact URL that crashed.
  2. Edit Your Content: Go into your CMS (like WordPress) and edit the page you just scanned. Find where that specific link was placed.
  3. Update or Remove: If it's an external link, try to find a replacement source. If no replacement exists, simply remove the hyperlink entirely. If it's an internal link, set up a 301 Redirect pointing the old URL to the most relevant live page on your site.

The Hidden Cost of Redirect Chains

While scanning for 404s is critical, our tool also highlights 30x Redirects in yellow. Why? Because chaining redirects kills your "Link Equity."

If Page A links to Page B, but Page B redirects to Page C, Google's crawler loses a small percentage of its ranking power during that jump. It also slows down your page load speed for human users. Our tool allows you to identify these redirects so you can manually update the link on Page A to point directly to Page C, bypassing the redirect entirely.
