What is a 404 Page Checker?

A 404 link checker is a software solution that assesses websites for broken or dead links. These hyperlinks, when clicked, lead to unavailable pages or 404 errors, negatively impacting the user experience and SEO. Search engines may perceive sites with multiple inactive links as poorly maintained.

Our free online dead link checker tool helps you by:

  • Checking your website or blog for dead hyperlinks. You’re able to check up to 150 links for free; you can check an unlimited number of references with any of our paid plans.
  • Identifying errors and making suggestions for opportunities to best optimize your website.
  • Reporting error codes for any broken URLs —including 404 and 502 errors and 301 redirects.
  • Fixing end-user usability issues to remove problematic redirects.
  • Providing high-value links for your website through broken link outreach features.
  • Scanning both internal and external hyperlinks.
  • Regularly monitoring the website for any new broken links that may appear and promptly fix them.

Domain and Distinct URL Check Capabilities of the Free Website Error Checker

There are two methods to check for 404 errors on a website, namely by domain or by searching on a specific page. Opting for the domain check is useful if you want to verify all links on a website and spot any dead URLs across the entire site.

However, the URL check is more suitable if you need to focus on a specific page, including all its links and related data, such as HTTP status codes. Select the method that suits your needs, input the domain or URL, and use the “Find broken links” button. Once initiated, the tool starts analyzing your site data.
