Frequently Asked Questions
What is an HTTP status code?
An HTTP status code is a three-digit response a web server sends back indicating the result of a request — such as 200 (success), 404 (not found), or 301 (permanent redirect).
What does a 404 error mean?
404 means "Not Found" — the server couldn't find the requested page, often due to a broken link, deleted content, or mistyped URL.
What's the difference between a 301 and 302 redirect?
301 is a permanent redirect (search engines transfer ranking signals to the new URL), while 302 is a temporary redirect (the original URL is expected to be used again, and ranking signals typically stay with it).
Is this tool free to use?
Yes, completely free with no signup, no limits and no software to install.
Is my data saved anywhere?
No — lookups run on request and are not stored or linked to you.
Why do I need to check status codes for SEO?
Broken links (404s), redirect chains, and server errors (5xx) can hurt both user experience and search rankings — regularly checking status codes helps catch and fix these issues.
What does a 500 error mean?
500 is a generic "Internal Server Error" — it indicates something went wrong on the server itself, rather than a problem with the request, and typically requires investigation by the site owner.
What is a redirect chain, and why is it bad for SEO?
A redirect chain is when one URL redirects to another, which redirects again, and so on — each hop adds load time and can dilute SEO value, so chains should generally be simplified to a single direct redirect.
Does this follow redirects to show the final destination?
Yes, typically the checker shows both the initial status code and follows through any redirect chain to reveal the final destination URL and its status.
Is this useful for auditing a whole website's links?
For checking individual URLs, yes — for auditing an entire site's links at scale, a dedicated site crawler tool designed for bulk checking would be more efficient.
The HTTP Status Code Checker reveals the exact status code a URL returns — whether it loads successfully, redirects, or fails — without needing to open browser developer tools.
Why Status Codes Are Worth Checking Directly
A URL that looks fine when visiting normally in a browser might still be masking an underlying issue, since browsers often follow redirects silently and don't clearly surface the exact code returned at each step. Checking the raw status code reveals what's actually happening at the server level, which is essential information a normal page view doesn't show.
Status Code Ranges Worth Knowing
- 2xx (Success) — the request completed successfully; 200 is the standard "OK" response for a normally loading page.
- 3xx (Redirection) — the resource has moved; 301 signals a permanent move, 302 a temporary one, each treated differently by search engines.
- 4xx (Client Error) — the request itself has a problem; 404 means the page doesn't exist, 403 means access is forbidden.
- 5xx (Server Error) — something went wrong on the server's end while processing an otherwise valid request, such as 500 (internal server error) or 503 (service unavailable).
Common Use Cases
Auditing a site for broken links returning 404s, confirming a redirect implementation returns the correct 301 rather than a 302, and diagnosing why a page isn't appearing in search results by checking whether it's actually accessible to crawlers.
