Free Website Dead Link Checker
Crawl your entire website to uncover 404 Not Found errors, broken external URLs, and redirect chains. See the exact source pages where dead links are located so you can fix them before they damage your SEO rankings.
How Our Free Dead Link Checker Works
A simple 3-step engine that detects broken 404 links and maps them back to their exact source pages.
Automated Site Crawl
Our crawler starts from your homepage, checks your XML sitemap, and traverses internal HTML pages up to 50 levels deep to extract every single anchor URL.
Concurrent Status Probing
Every unique link is tested with concurrent HTTP requests measuring exact status codes: 200 OK, 404 Not Found, 301/302 redirects, and 500 server errors.
Pinpoint Exact Source Pages
Instead of guessing where a broken URL lives, our report gives you the exact source page and anchor text so your developers can edit or remove the dead link immediately.
Why Dead & 404 Links Damage Your Website
Leaving broken links unattended negatively impacts search engine crawl budgets, user conversion rates, and SEO equity.
Wasted Crawl Budget
Search engine bots like Googlebot have limited crawl time. Encountering repeated 404s causes bots to abandon crawling your high-priority money pages.
High Bounce Rates
When visitors click a dead link and land on an ugly 404 error, over 73% hit the back button and go to a competitor instead of browsing further.
Broken PageRank Equity
Internal links pass valuable PageRank link juice throughout your domain. When an internal link leads to a 404, that ranking authority vanishes into a black hole.
Easy 301 Redirect Fixes
Once identified with our tool, you can easily point obsolete URLs to relevant new content using permanent 301 redirects or update the HTML anchor.

Dead Link Checker FAQs
What is a dead link (broken link)?
A dead link (also called a broken link) is a hyperlink on a website that points to a webpage, image, or resource that no longer exists or cannot be reached. When clicked, the server typically responds with an HTTP 404 Not Found error.
How does this tool check all pages on my website?
Our crawler starts at your provided URL, inspects your XML sitemap if present, and follows internal links across your domain up to 50 pages deep. It extracts all anchor tags (<a href>) and concurrently tests their HTTP response codes in real time.
Why is showing the "Found On Source Page" so important?
Knowing that a 404 URL exists is only half the battle. Our report lists the exact source page(s) where the link was found, so your developers or content editors can open the specific page and fix or remove the bad link in seconds.
What is the difference between internal and external broken links?
An internal broken link points to a page on your own domain that returns 404 (for example, a deleted blog post). An external broken link points to a third-party website that has moved or shut down. Both harm user experience, but internal 404s severely hurt your SEO architecture.
How can I fix broken 404 links once found?
For internal pages that were moved or deleted, set up a 301 permanent redirect pointing to the most relevant active URL. For typos in anchor URLs, simply edit the page and correct the address. For external broken sites, update or remove the hyperlink.
