Broken link checker

Find the dead links on your site and stop leaving visitors on a 404 page. Enter your address, verify with Search Console, and the first scan is on us.

Free · nothing to install on your site · scans only your own verified domain.

How it works

Three steps, no code on your site

  1. 1

    Verify your site

    Connect Google Search Console and pick one of your verified sites.

  2. 2

    Start the scan

    no404 walks your links and lists the addresses that do not respond, along with the pages they sit on.

  3. 3

    Write the redirect

    Send the 404s to bulk matching in one click. no404 finds the closest page in your catalog and you approve the 301.

Why it matters

A broken link costs you in three places

The visitor leaves

Someone who can't find what they were looking for lands on a 404 page. Most hit the back button, return to the search results and never come back.

The ad click is wasted

An ad pointing to a removed product sends the click you paid for to an empty page.

Crawl budget goes to waste

Dead addresses eat crawl budget. Google reaches your newer pages later than it should, and sometimes not at all.

Why we ask for verification

We do not scan just any site

A scan sends hundreds of consecutive requests to a site's server. Doing that to an address whose ownership has not been proven is an attack from that owner's point of view, and firewalls read it the same way, even though we pay for the traffic.

So the only thing you can scan is a domain proven to be yours through Google Search Console. We drew the line there on purpose.

What the scan finds

The report is a to-do list

  • Broken addresses and where they are linked

    Every broken link is listed together with the page that links to it. You don't have to hunt for where the fix goes.

  • Dead links to other sites

    Links to sites that shut down are reported too. You can't redirect those, but you can change the link in your text.

  • Pages with no internal link

    Pages that are in your sitemap but get no link from anywhere on your site are listed separately. They aren't broken, but no visitor can click their way there, and often Google can't either.

    The numbers, the status codes and the full list in one file.

FAQ

Frequently asked questions

What is a broken link?
A link that leads to a page that no longer exists. The server usually answers 404 (not found) or 410 (gone). It happens when a product is deleted, an address changes, or a link is mistyped.
Why is Search Console verification required?
A scan sends hundreds of requests to the target server in a short window, and doing that without the owner's knowledge is not something we're willing to do. Search Console verification is simply the easiest way to prove permission.
Is it really free?
One scan per verified domain is free and we do not ask for a card. Regular scanning comes as a monthly allowance in the paid plans.
How much does the free scan cover?
The trial scan starts at your home page, goes one step further and checks those links. Deeper scans can be selected on paid plans.
Do I need to add code to my site?
No. Scanning works entirely from the outside. A snippet or plugin is only needed if you also want 404s redirected automatically.
What happens after the broken links are found?
The 404 and 410 addresses go to bulk matching; no404 finds the closest page in your live catalog and suggests the redirect for you to approve.

How many broken links does your site have?

The first scan is free for your verified domain. The trial scan runs at a depth of 1 and you can download the result as a PDF.
