HTTP Status Code Checker Online

If you recently migrated a website or changed your domain name, you must ensure your server is returning the correct 301 redirects, or Google will completely destroy your SEO rankings. This diagnostic tool is built to ping any URL and expose the exact raw HTTP header response the server sends back.

Understanding the 200, 300, 400, 500 Blocks

The internet operates entirely on HTTP status codes. 200 means Success. 300 block indicates Redirects (where 301 is permanent, and 302 is temporary). 400 block indicates Client Errors (like a 404 Not Found, meaning the user typed the wrong URL). 500 block indicates Server Errors (like a 502 Bad Gateway, meaning your backend crashed).

The CORS Limitation

Web browsers enforce a strict security policy called CORS (Cross-Origin Resource Sharing). If you try to ping a website via client-side JavaScript, the browser will often block the response to prevent malicious scraping. To bypass this, this specific tool utilizes a secure backend proxy to fetch the raw HTTP headers unhindered.

Following Redirect Chains

A common SEO disaster is the "Redirect Chain." If URL A redirects to URL B, which redirects to URL C, Googlebot will often give up, and the page will lose its indexing. This tool exposes the entire path of the request so you can identify and flatten inefficient server hops.
