What Is the HTTP Status Checker?

Every web response starts with a three-digit status code that tells browsers and search engines what happened. This tool requests a URL and shows the code it returns, such as 200 OK, 301 Moved Permanently or 404 Not Found.

When to Use It

To check that important pages return 200 and not an error.
To confirm that removed pages return 404 or 410, and moved pages 301.
When Google Search Console reports server errors or soft 404s.

How to Use It

Enter a URL or domain.
Read the returned status code and its meaning.

Understanding the Result

200 is what normal pages should return. 301 and 308 are permanent redirects, 302 and 307 temporary ones. 403 means access is forbidden, 404 not found, 429 too many requests, and 500, 502, 503 and 504 are server-side failures that also hurt search rankings if they persist.

Limitations

Some sites block automated requests or show different responses by country or device. To see every step of a redirect, use the Redirect Checker; look up any code with the HTTP Status Code Lookup.

Frequently Asked Questions

A 301 signals a permanent redirect (search engines transfer ranking signals to the new URL); a 302 signals a temporary one (the original URL is expected to be used again, and ranking signals generally stay with it) - using the wrong one is a common, impactful SEO mistake.

A page can display content while still returning a non-200 status invisible to a casual look (for example, a custom error page incorrectly served with a 200 status, or vice versa) - search engines and automated tools rely on the actual header, not visual appearance.

4xx codes indicate a client-side issue (like 404 Not Found - the specific resource doesn't exist); 5xx codes indicate the server itself encountered an error while trying to fulfill a valid request - a much more serious signal about server health.

Generally yes, but a "soft 404" - a page that returns 200 while displaying "page not found" content - can confuse both users and search engine crawlers, which is worth checking for on any page meant to signal it doesn't exist.

403 means the server understood the request but is refusing to fulfill it - often due to permissions, IP blocking, or a security rule - as opposed to 404, which specifically means the resource wasn't found at all.

Indirectly, yes - persistent 5xx errors can affect crawl budget and indexing, and improperly configured redirect chains or status codes can prevent ranking signals from consolidating onto your intended canonical URL.
