What Is an HTTP Status Code Checker?
An HTTP status code checker is a tool that sends a request to a URL and identifies the HTTP response returned by the server. These response codes help you determine whether a webpage is working correctly, redirecting somewhere else, unavailable or returning an error.
For SEO audits, checking HTTP response codes can help you identify:
- Working URLs returning 200 OK
- 301 permanent redirects
- 302 temporary redirects
- 307 temporary redirects
- Broken pages returning 404 Not Found
- Removed pages returning 410 Gone
- Authentication issues returning 401 Unauthorised
- Server problems such as 500 Internal Server Error
- Temporary server problems such as 503 Service Unavailable
- Redirect chains and unexpected final URLs
How to Use the Bulk URL Checker
- Enter or paste the URLs you want to check, with one URL per line.
- Add up to 20 URLs in a single batch.
- Click Check Status Codes.
- Review the HTTP status code returned for each URL.
- Check the final URL and redirects to identify unexpected redirect behaviour.
- Export the results to CSV if you need to analyse or share the data.
This makes the tool useful as both a Bulk URL Checker and a Batch Link Checker for technical SEO audits, website migrations and routine website maintenance.
Common HTTP Status Codes Explained
| HTTP Status Code | Meaning | What It Usually Means |

| 204 No Content | Successful | The request succeeded, but the server returned no response body. |
| 301 Moved Permanently | Permanent Redirect | The requested URL has permanently moved to another URL. |

| 308 Permanent Redirect | Permanent Redirect | The resource has permanently moved while preserving the request method. |
| 401 Unauthorized | Client Error | Authentication is required before the requested resource can be accessed. |
| 403 Forbidden | Client Error | The server understands the request but refuses access. |

Why HTTP Status Codes Matter for SEO
Search engines need to crawl URLs successfully to understand your website. Incorrect HTTP response codes can waste crawl resources, prevent important pages from being indexed and create poor experiences for visitors.
Regularly checking URLs can help you identify technical SEO problems before they affect larger sections of your website.
Find Broken 404 and 410 URLs
A 404 status code means the requested resource cannot be found. A 410 error communicates that the resource is no longer available and is expected to be permanently gone.
Review 404 and 410 URLs to determine whether they should remain unavailable, be restored or redirect to another genuinely relevant page.
Check 301 and 302 Redirects
A 301 Moved Permanently response should generally be used when a URL has permanently changed.
A 302 Found response indicates a temporary redirect. If a page has permanently moved but continues returning a 302 status code, review whether a permanent redirect would better reflect the intended change.
Our checker lets you review the returned status and final destination URL so unexpected redirects are easier to find.
Identify 307 Temporary Redirects
A 307 redirect indicates that a resource is temporarily available at another location while keeping the original request method unchanged.
Checking 307 redirects can be especially useful during technical audits when you need to determine whether redirects are intentional or whether a permanent redirect would be more appropriate.
Check 401 Unauthorised Responses
A 401 status code indicates that authentication credentials are required to access the requested resource.
If an important public page unexpectedly returns an HTTP 401 error, search engines and normal visitors may be unable to access the content. Investigate authentication, server or security settings when this response appears on pages that should be public.
Find 503 Service Unavailable Errors
A 503 error code means that a server is temporarily unable to handle the request, which can happen during maintenance or periods of server overload.
Occasional temporary 503 responses may be expected, but persistent 503 errors should be investigated because users and crawlers may be unable to access the affected URLs.
Check 204 No Content Responses
A 204 status code means the request was successfully processed but the server returned no response content.
A 204 response may be appropriate for certain requests, but an important webpage normally expected to display HTML content should be reviewed if it unexpectedly returns 204 No Content.
Check Redirect Chains and Redirect Loops
Redirect problems can make websites harder for users and search engines to navigate.
A redirect chain happens when one URL redirects through several URLs before reaching its final destination:
URL A → URL B → URL C → Final URL
Where possible, unnecessary redirect steps should be removed so the original URL points directly to the intended destination.
A redirect loop occurs when URLs repeatedly redirect between each other and never reach a working final page:
URL A → URL B → URL A
Redirect loops should be fixed because visitors and search engine crawlers cannot successfully access the intended content.
Check Canonical Redirects
Canonical URLs and redirects serve different purposes but should work together consistently.
If a URL permanently redirects to another page, review the canonical configuration on the destination page as part of your technical SEO audit. Conflicting redirect and canonical signals can make your preferred URL structure less clear.
Use the HTTP Status Code Checker to identify redirects first, then review the canonical tags on the relevant pages.
When Should You Use a Batch Link Checker?
A bulk HTTP status checker is particularly useful when:
- Migrating a website to a new domain or URL structure
- Changing webpage URLs
- Auditing old blog posts or landing pages
- Checking URLs from an XML sitemap
- Reviewing internal or external links
- Troubleshooting indexing problems
- Checking redirects after a website redesign
- Finding 404 and 410 URLs
- Validating 301, 302 and 307 redirects
- Investigating 500 or 503 server errors
- Reviewing large lists of URLs from Google Search Console or SEO tools
Instead of checking every URL manually in a browser, paste your list into the Bulk URL Checker and review the results together.
Frequently Asked Questions
What is a Bulk URL Checker?
A Bulk URL Checker lets you check multiple URLs at the same time instead of testing each URL individually. It can help identify successful pages, redirects, broken URLs and server errors across a list of webpages.
What is a Batch Link Checker?
A Batch Link Checker checks a group of URLs in one request or workflow. It is particularly useful for SEO specialists, developers and website owners reviewing large URL lists during technical audits.
What does HTTP 200 mean?
HTTP 200 OK means the request was completed. For a normal indexable webpage, a 200 response generally indicates that the page is accessible.
What is a 301 status code?
301 Moved Permanently means that a resource has permanently moved to another URL. It is commonly used when URLs are permanently changed, pages are consolidated, or websites are migrated.
What is a 302 status code?
302 Found indicates a temporary redirect. The requested URL temporarily points visitors to another location.
What is a 307 redirect?
307 Temporary Redirect means that a resource has temporarily moved to another URL while the HTTP request method should remain unchanged.
What does a 401 status code mean?
401 Unauthorised means authentication is required to access the requested resource. If a public webpage returns 401 unexpectedly, its access or authentication configuration should be reviewed.
What is a 404 status code?
404 Not Found means the server cannot find the requested resource. Broken internal links pointing to 404 URLs should be reviewed and corrected where appropriate.
What is a 410 error?
410 Gone indicates that the requested resource is no longer available and that its removal is expected to be permanent.
What does a 503 error code mean?
503 Service Unavailable means the server is temporarily unable to handle the request, often because of maintenance or temporary overload.
What does HTTP 204 mean?
204 No Content means that the server successfully processed the request but returned no response body.
Can this tool check redirects?
Yes. The checker can help identify redirecting URLs and show their final destination, making it easier to audit 301, 302 and other redirects.
Can I check multiple URLs at once?
Yes. Enter one URL per line and check up to 20 URLs in a single batch.
Is the HTTP Status Code Checker free?
Yes. You can use SEO Acronym’s HTTP Status Code Checker for free to check URLs and identify HTTP response codes, redirects and broken pages.
