How this free tool helps
Review 200, redirect, client-error and server-error responses. Redirect chains are traced with bounded requests and protected URL handling.

Free HTTP Status Code Checker
Check a public URL for HTTP response codes, redirects and the final destination in the redirect chain. Quickly identify 200, 3xx, 4xx and 5xx responses that may affect crawling or user access.
What each response class tells you
2xx responses normally indicate successful access, 3xx responses move users and crawlers, 4xx responses indicate client-side unavailability and 5xx responses indicate server failures.
Common mistakes to avoid
Long redirect chains, soft-404 behaviour and important pages returning intermittent errors can waste crawling and degrade user experience.
What to do after using this tool
Correct the underlying server or routing rule, update internal links to final destinations and retest the exact URL after deployment.
Frequently Asked Questions
What do 200, 3xx, 4xx and 5xx responses mean?
A 2xx response generally indicates success, 3xx indicates redirection, 4xx indicates a client/request problem such as not found, and 5xx indicates a server-side failure. The exact code provides more detail.
Why do HTTP status codes matter for SEO?
Crawlers use HTTP responses to understand whether content is available, moved or unavailable. Incorrect codes can waste crawling, preserve broken URLs or make a valid page appear inaccessible.
Can the checker follow redirects?
Yes. For public URLs it can report redirect hops within bounded request limits so you can see the response path and final destination.
What is the difference between 404 and 410?
Both indicate unavailable content, while 410 explicitly states that the resource is gone. The appropriate response depends on whether the URL is missing, permanently removed or has a relevant replacement.
What does a 429 response mean?
HTTP 429 means too many requests. It usually indicates rate limiting, so repeated automated checks should slow down rather than treating the response as a normal page error.
