Check the HTTP status code of any URL online free - no login. Instantly see if a URL returns 200 OK, 301 redirect, 404 not found, 500 error, or any other HTTP response code.
HTTP status codes tell you whether a URL is working correctly, redirecting somewhere, or returning an error. For SEO, the difference between a 301 (permanent) and 302 (temporary) redirect affects how link equity passes. For site maintenance, catching 404s and 500s before users do prevents ranking drops.
Enter any URL to see its HTTP response code - 200 OK, 301 redirect, 404 not found, 500 server error - along with the final destination URL after all redirects have resolved.
Check if a page returns 200 OK after a site migration, verify that a redirect chain from old URL to new URL resolves correctly, debug 404 errors found in Google Search Console, check if a server is returning 500 errors, verify that HTTPS redirects are working correctly, and audit redirect chains to find unnecessary hops that slow page load.
The most common question is about 301 vs 302 redirects. A 301 (permanent) redirect signals to Google that the original URL has moved permanently - link equity passes to the destination. A 302 (temporary) redirect signals that the move is temporary - Google may continue indexing the original URL.

Common questions about this tool and how to use it.
HTTP status codes are grouped by their first digit: 2xx means success (200 OK, 201 Created). 3xx means redirect (301 Permanent, 302 Temporary, 304 Not Modified). 4xx means client error (400 Bad Request, 401 Unauthorized, 403 Forbidden, 404 Not Found). 5xx means server error (500 Internal Server Error, 503 Service Unavailable). The most important for SEO and debugging are 200, 301, 302, 404, and 500.
A 301 redirect (Moved Permanently) tells search engines that the original URL has moved permanently - Google passes the link equity (PageRank) of the original URL to the destination URL. A 302 redirect (Found / Moved Temporarily) signals a temporary move - Google may continue indexing the original URL and does not pass full link equity to the destination. Use 301 for permanent URL changes; use 302 only when the original URL will return.
A 500 Internal Server Error means something went wrong on the server - not a client issue. Common causes: PHP or application code error, database connection failure, memory limit exceeded, corrupted .htaccess file, or a server misconfiguration. Check your hosting control panel for error logs, which will show the specific cause.
A 404 Not Found error means the URL does not exist on the server. If you moved or deleted a page: set up a 301 redirect from the old URL to the replacement URL. If the URL was mistyped in an external link: contact the linking site to correct the URL. In Google Search Console, monitor 404 errors and prioritize fixing those that still receive traffic or have inbound links.
Google's documentation says it follows redirects, but best practice recommends keeping redirect chains to a maximum of 3–5 hops. Each additional hop adds latency and dilutes the link equity passing through the chain. If you have a chain like A→B→C→D, consolidate it to A→D. Google may drop redirect chains with too many hops from its index.
