Status code checker

What is the Status code checker?

The Status code checker verifies the HTTP status codes of many URLs at once. Every URL on the web responds to a request with a status code, a three-digit number that describes the outcome of the request, such as a successful load, a redirect, or an error. The tool takes a list of URLs as input and returns the status code for each one, giving you a quick health report across a whole set of addresses.

Status codes are the language servers use to tell clients how a request went. A code in the 200 range means the page loaded, the 300 range signals a redirect, the 400 range indicates a problem with the requested URL, and the 500 range means the server failed. Checking many URLs at once turns scattered uncertainty about a site's pages into one clear list of what is working and what is not.

The tool is designed for the reality that sites grow beyond a handful of pages. When a site has dozens or hundreds of URLs, checking each one individually is impractical, and problems tend to hide among the pages you do not visit. A batch check surfaces the entire picture at once, so nothing slips through because it was never looked at.

What the Status code checker does

The tool accepts a batch of URLs and checks each one to determine its HTTP status code. You provide the list of addresses, the server requests each URL, and the response code for every address is reported back. The output pairs each URL with the status code it returned, so you can scan the list and immediately see which pages are healthy and which are returning errors.

Because the tool processes the URLs in a single batch, it is practical for checking pages that are too numerous to visit by hand. A sitemap, a list of newly published pages, or a set of old links can be verified in one submission, producing a snapshot of the current state of every address on the list.

The check reflects the response each URL gives at the time of the request. Codes can change as pages are updated, moved, or taken down, so the tool is best understood as a point-in-time report that can be re-run whenever you need a fresh picture of a set of URLs.

The results are organized to be acted on quickly. By pairing each URL with its code, the report lets you separate healthy pages from problems at a glance, and because the whole batch is checked in one run, the list is complete rather than a sample you have to assemble yourself.

The check also works as a monitoring tool when run repeatedly. A series of snapshots taken over time shows which URLs have been stable and which have drifted into errors, so problems are caught early rather than discovered after they have already cost traffic.

The tool's design favors speed of review. Instead of a verbose report, it pairs each URL with its code so the list stays compact and scannable, letting you focus immediately on the entries that need a decision rather than reading through the healthy ones.

That focus on quick review matters at scale. A batch of many URLs produces a report that can be worked through in minutes, and because the format stays the same across runs, you can compare results from one check to the next without re-learning how to read them.

How to use the Status code checker

Checking a batch of URLs is straightforward. Gather the addresses you want to verify and follow the steps below.

1. Collect the URLs you want to check, such as the pages in a sitemap or a list of links you plan to reference.
2. Enter the URLs into the input field on the tool page, placing each address on its own line so the batch is processed cleanly.
3. Submit the form so the list is posted to the server and each URL is requested to determine its status code.
4. Review the output, noting which URLs returned successful codes and which returned errors or redirects.
5. Follow up on any unexpected codes, such as fixing pages that return errors or updating URLs that no longer resolve as expected.

How to get better results

• Check URLs in batches that share a purpose, such as all pages from one section, so the results are easy to interpret and act on.
• Include the full protocol in each URL, such as the https prefix, so each address is requested exactly as intended.
• Re-run the check after making changes to a page or server, since status codes can change the moment a configuration is updated.
• Look beyond error codes at redirects too, since an unexpected redirect can send visitors somewhere they did not intend to go.
• Combine the status check with a review of the pages that return errors, so you understand whether each failure needs a fix or a removal.
• Keep a record of past checks so you can see when a URL began returning a new code and correlate it with site changes.
• Check the URLs you link to from your pages as well as your own pages, since external links can break just as easily as internal ones.

Why the Status code checker matters

Status codes are the foundation of how search engines understand a site's pages. A page that returns an error code is a page search engines cannot index as intended, and a page that redirects unexpectedly may pass its value somewhere unwanted. Keeping the codes across your pages healthy is a basic condition for a site to perform as planned, and checking them in bulk is the only practical way to do that across a large set of URLs.

The checker also prevents avoidable mistakes. A link that goes to a dead page, a page that was moved without a redirect, or a configuration error that breaks a whole section can all go unnoticed without a status check. Surfacing those codes early turns a potential loss of traffic into a fixable list, which is why a batch status checker is a standard part of maintaining any site with more than a handful of URLs.

The batch approach is what makes the check genuinely useful. A single URL can be tested by visiting it, but the problems that hurt a site are rarely confined to one page. Checking the whole set in one pass reveals the pattern, whether that is a broken section, a run of stale links, or a few isolated failures, and that pattern is what guides the fix.

Status checks also give you a defensible record. When a page stops performing or a migration goes wrong, a history of codes shows when the change happened and what the URL returned before and after. That context turns troubleshooting from guesswork into a comparison of concrete states.

When to use the Status code checker

• When you are auditing the URLs of your site and want a complete picture of which pages are returning errors.
• When you have migrated a site or changed its structure and need to confirm that URLs respond with the codes you expect.
• When you are preparing a sitemap or submitting a list of pages and want to verify every address is live before submitting.
• When a page or section is reported as broken, and you want to check the status codes of the related URLs to isolate the cause.
• When you maintain a list of external links and want to confirm the destinations still return healthy codes.

Frequently asked questions

What is an HTTP status code?

An HTTP status code is a three-digit number a server returns with every response, describing the result of a request. It tells you whether a page loaded, redirected, or failed, and is the standard way to check the health of any URL.

What do the different code ranges mean?

Codes in the 200 range indicate success, the 300 range indicates redirection, the 400 range indicates a problem with the request such as a missing page, and the 500 range indicates a server-side failure.

Can the tool check URLs that are not on my own site?

Yes. The tool requests each URL you provide and reports its status code, so it can check any address, whether it belongs to your site or points to an external destination.

How should I format the list of URLs?

Enter one full URL per line, including the protocol. This keeps each address distinct and ensures every URL is requested exactly as you intended.

How often should I check status codes?

Check whenever you make significant site changes, and periodically as part of regular maintenance. Because codes change as pages are moved or removed, periodic checks keep you aware of problems before visitors find them.

What should I do when a URL returns an error code?

First confirm the code is consistent, since a temporary failure can clear on its own. If the URL consistently returns an error, either fix the underlying problem, update references to it, or remove it if the page is no longer needed.
