404 page checker

404 page checker tests a generated missing URL and reports its HTTP status. Find misleading success responses and review how your website handles missing pages.

What is 404 page checker?

404 page checker tests how a website responds when a requested page does not exist. It requests a generated missing path and reports whether the server returns an appropriate 404 status. This helps you investigate error handling separately from the design of the error page.

How to use this tool

Enter a URL on the website you want to check, then submit the test. Review the generated test address, returned status code, and result. Open that test address in a browser when you also want to evaluate whether the error page provides useful navigation for visitors.

Understanding the results

A page can display a not-found message while returning a success response. Conversely, a correctly reported 404 can still have an unhelpful visual design. Treat the response code and the visitor experience as separate checks. The result covers the generated path, so route-specific rules may behave differently elsewhere. Test representative missing paths after changing application routing or supported server settings.

Frequently asked questions

Does this find every broken link on my site?

No. It checks the website's response to a generated missing URL. A broken-link audit requires examining the actual links published across your pages.

Should the error page redirect to the homepage?

A homepage redirect can hide the original missing-page condition. Choose behavior that fits the route and confirm that visitors and crawlers receive an accurate response for genuinely missing content.
