HTTP Status Checker

What Is This HTTP Status Checker Tool?

This free tool checks the HTTP status code returned by any URL the three-digit code a server sends back to indicate whether a request succeeded, failed, or got redirected elsewhere. Paste in a URL, and the tool tells you instantly whether it returns a 200 OK, a 404 Not Found, a 500 server error, or something else entirely, without needing to open browser DevTools or guess based on how the page happens to look.

It’s built for anyone who needs a fast, reliable way to confirm a URL is actually working as expected site owners auditing broken links, SEO professionals checking crawlability, and developers verifying a deployment went smoothly.

How to Use the HTTP Status Checker

1. Enter the URL you want to check into the input box. You can check a single URL, or paste a list of several if you’re auditing more than one at a time.
2. Run the check. The tool sends a request to each URL and captures the exact status code the server returns.
3. Review the results. Each URL comes back with its status code and a plain-language explanation of what that code actually means, so you’re not stuck memorizing the full HTTP status reference.

If a URL redirects before landing on its final destination, the tool notes that too, so you can see both the initial and final status in context. For a full hop-by-hop breakdown of a redirect chain, the Redirect Checker is the tool built specifically for that.

Common HTTP Status Codes Explained

• 200 OK the request succeeded and the page loaded normally. This is what you want for any live, indexable page.
• 301 / 302 (Redirects) the URL points somewhere else, either permanently (301) or temporarily (302). Not an error on its own, but worth confirming the redirect target is actually correct.
• 404 Not Found the server couldn’t find anything at that URL. Common after deleting a page, changing a slug, or linking to a typo’d address. If the URL in question is meant to have a canonical version elsewhere, the Canonical Checker can confirm that setup is pointing somewhere that’s actually live.
• 410 Gone similar to a 404, but it explicitly signals the page was intentionally removed and isn’t coming back, which some search engines treat a little differently for deindexing.
• 403 Forbidden the server understood the request but is refusing to fulfill it, often because of permissions or access restrictions.
• 500 Internal Server Error something went wrong on the server itself, unrelated to the specific URL requested. Usually points to a bug, misconfiguration, or server overload.
• 503 Service Unavailable the server is temporarily unable to handle the request, often due to maintenance or a traffic spike.

Why Checking Status Codes Matters

• Broken links hurt user experience and SEO. A page returning a 404 that’s still linked internally or externally wastes crawl budget and creates a dead end for anyone who clicks through.
• Soft 404s are hard to catch manually. Some pages return a 200 OK status while actually displaying a “page not found” message a soft 404. These mislead both users and search engines, since the server is claiming success while the content says otherwise, and they’re genuinely difficult to spot just by browsing the site.
• Server errors can silently affect crawling. If a page intermittently returns 500 or 503 errors, it can hurt how often and how thoroughly search engines crawl the rest of the site, even if the page loads fine most of the time.
• Confirming redirects resolve correctly. After setting up a redirect, checking the final status code confirms it actually lands on a working page rather than another dead end. If you also want to see the response headers behind that final page, the HTTP Header Checker picks up right where this tool leaves off.

Who Uses This Tool

• SEO professionals auditing a site for broken links, soft 404s, or server errors as part of a technical SEO review.
• Developers verifying that a deployment or configuration change didn’t quietly break existing URLs.
• Content editors checking that internal and external links in an article still resolve correctly before publishing.
• Website owners troubleshooting reports of broken pages, or investigating a drop in search traffic tied to crawl errors.

FAQ

What does a 404 status code mean? It means the server couldn’t find any content at the requested URL commonly caused by a deleted page, a changed URL slug, or a typo in the link.

What’s a “soft 404” and why does it matter? A soft 404 is a page that returns a 200 OK status, indicating success, while actually showing “not found” content to the user. That’s misleading to search engines and can leave a broken page indexed longer than it should be.

Is this tool free to use? Yes, completely free, with no sign-up and no usage limit.

Can I check multiple URLs at once? Yes, paste a list of URLs and the tool checks each one, returning results for the full batch. If the list came from a sitemap, the XML Sitemap Validator can check the sitemap’s structure and every listed URL in one pass.

What’s the difference between a 403 and a 404 error? A 404 means nothing exists at that URL. A 403 means something exists, but access is being denied, often due to permissions or server-level restrictions.

Does this tool follow redirects automatically? Yes, if a URL redirects, the tool shows the final status code after following the chain, and you can use the Redirect Checker for a full hop-by-hop breakdown.
