What we detect

Every type of broken link, covered.

A comprehensive scan that goes far beyond simple 404 checking — we analyse every type of link and asset on your website.

🔗

Broken Internal Links

Every internal link pointing to a non-existent page. Most damaging for SEO — they break the link equity flow between your pages.

🌐

Broken External Links

Outbound links to dead external websites. Signals poor content maintenance to search engines and damages visitor trust.

🖼️

Missing Images

Detects broken image src attributes — including files in subfolders, images with spaces in filenames, and relative paths.

↪️

Redirect Chains

Identifies URLs that redirect to other URLs. Excessive chains slow your site and dilute PageRank through internal links.

📄

Empty & Thin Pages

Flags pages with very little text content. Google penalises thin content and lowers the quality score of your entire website.

🎨

CSS & JS Resources

Checks stylesheets and JavaScript files are loading correctly. Broken CSS breaks layouts; broken JS disables functionality.

🔤

Web Font Files

Verifies .woff, .woff2, .ttf and .eot font files are accessible. Missing fonts cause text to render in fallback fonts.

🏷️

Open Graph & Meta URLs

Checks URLs in og:image, og:url, and other meta tags. Broken OG images make your pages look broken on social media.

🔍

Source Code Viewer

Click any broken link to see the exact line in your source HTML where it appears — highlighted and ready to fix.

Process

How it works in five steps.

Our crawler mimics a search engine bot to give you an accurate picture of what Googlebot actually sees.

Enter Your URL

Paste your website address and choose scan depth — up to 500 pages.

Crawl & Discover

The crawler visits your homepage and follows every internal link it finds.

Check Every Link

Each URL is verified. Images, CSS, JS, and fonts checked in parallel batches.

Review Results

Results stream in real time. Filter by status, search by domain or URL.

Fix & Export

Use the source viewer to find the exact code line, then export a CSV report.

Reference

Understanding HTTP status codes.

Every link on your website returns a status code. Here's what each one means for your SEO and user experience.

Code	Status	Meaning	SEO Impact
200	OK — Working	The link is healthy and returns the expected page.	✓ Positive
404	Not Found — Broken	Page doesn't exist. Wastes crawl budget and frustrates visitors.	✗ Harmful
500	Server Error	Server encountered an error. Repeated errors signal hosting problems.	✗ Harmful
403	Forbidden	Server refuses the request. Often misconfigured file permissions.	~ Warning
301	Permanent Redirect	URL has permanently moved. Each redirect wastes a small crawl budget.	~ Caution
302	Temporary Redirect	Temporary redirect. Switch to 301 if the move has been permanent.	~ Caution
—	Empty Page	Page loads (200) but has less than 200 characters of visible text.	~ Thin Content
0	Timeout / Unreachable	Server took too long to respond or is completely offline.	✗ Harmful

FAQ

Frequently asked questions.

How many pages can I scan for free?

You can scan up to 500 pages per scan, completely free with no sign-up required. Run as many scans as you like. Choose your depth from the dropdown: 25, 50, 100, 200, 300, or 500 pages.

Will scanning my website affect its performance?

Our crawler includes a small delay between requests (50ms) and uses parallel checking for non-page resources to minimise server load. For most websites the scan is unnoticeable. Consider running scans during off-peak hours if you have a resource-constrained server.

Why is a link showing as 404 when it works in my browser?

This can happen if the URL contains spaces or special characters that browsers encode automatically, the page requires a login or session cookie, or the server blocks requests without a browser-like User-Agent. Our checker sends a standard browser User-Agent to mitigate most of these issues.

What is an "empty page" and should I fix it?

An empty page loads successfully (HTTP 200) but has less than 200 characters of visible text after stripping HTML. Google considers these "thin content," which can lower your site's overall quality score. Add meaningful content or redirect these pages to a more relevant destination.

What does the Source button do in the results?

Clicking "Source" fetches and displays the HTML source code of the page containing the broken link. The exact line where it appears is highlighted in yellow so you can immediately find and fix it in your template or CMS.

How often should I run a link check?

For active websites that publish content regularly, once a month is a good baseline. Run additional scans after publishing large content batches, performing site migrations, changing your URL structure, or updating your CMS. E-commerce sites benefit from weekly checks.

Does this tool check JavaScript-rendered content?

No — like Googlebot's primary crawler, our tool checks the raw HTML returned by the server before JavaScript executes. Links only inserted by JavaScript (via React, Vue, Angular etc.) won't be detected. This accurately reflects what Googlebot sees for raw-HTML SEO purposes.
