HTTP Status Code Checker
Enter an HTTP status code to see its meaning and category. For live URL response testing, browser security restrictions may require a server-side checker.
How to Use the HTTP Status Code Checker
Enter an HTTP status code to see its category and plain-language meaning.
Practical Example
Entering 404 identifies a client-error response meaning the requested resource was not found, while 301 identifies a permanent redirect.
Factors That Affect the Result
The checker explains the code itself; a live website can return different codes depending on server rules, authentication, redirects or outages.
Frequently Asked Questions
What does HTTP 200 mean?
It generally means the request succeeded.
What does 404 mean?
It means the requested resource was not found at that location.
Why do status codes matter for SEO?
They tell crawlers whether URLs are available, redirected or returning errors.
Reading HTTP Status Codes
HTTP status codes describe how a server responded to a request. Codes in the 200 range generally indicate success, 300-range codes describe redirects, 400-range codes indicate client-side request or access problems, and 500-range codes indicate server-side failures. A 200 response does not automatically mean the page contains the expected content, and a redirect should be followed to confirm its final destination. When auditing a website, pay attention to repeated 404 errors, redirect chains and unexpected 5xx responses because they can affect users and crawlers. Some sites return different results depending on user agent, location, authentication or request method, so one check may not represent every visitor. For troubleshooting, combine the status code with response headers, page content and server logs when those sources are available.
