How the HTTP Status Code Checker Works
This tool sends an HTTP request to each URL and reports back the server's response. Here's the process:
- Enter your URLs — paste up to 50 URLs, one per line. The tool adds
https://if no protocol is specified. - Concurrent checking — all URLs are checked simultaneously using HTTP HEAD requests. If a server blocks HEAD, the tool automatically retries with GET.
- Collect response data — for each URL, it records the status code, status text, redirect location (if any), server header, content type, and response time.
- Summary and filtering — results are displayed in a sortable table with a color-coded summary showing the breakdown of 2xx, 3xx, 4xx, and 5xx responses.
Why HTTP Status Codes Matter for SEO
Status codes are the language between your server and search engine crawlers. Getting them wrong can silently destroy your rankings:
- Crawl budget waste — every 404, redirect chain, and server error wastes crawl budget. If Googlebot spends its time hitting broken URLs, it has less time to discover and index your actual content.
- Link equity loss — backlinks pointing to 404 pages are dead weight. Those links carry ranking value that you're throwing away. A simple 301 redirect recovers that equity.
- Indexing signals — a 200 means "index this." A 301 means "index the new URL instead." A 404 means "remove this from the index." A 503 means "come back later." Using the wrong code sends the wrong signal.
- User experience — visitors hitting 404s or 500s leave. High bounce rates from error pages send negative engagement signals to search engines and directly hurt conversions.
- Site migrations — during domain moves or CMS changes, bulk-checking all your URLs is essential. One missed redirect can mean losing your highest-ranking page.
For a deeper dive into redirect behavior, use the Redirect Checker to trace the full redirect chain of any individual URL, or the Sitemap Checker to verify that your sitemap only contains 200-status URLs. To find all broken links on a specific page, the Broken Link Checker scans every anchor tag and reports 404s, 5xx errors, and timeouts. Use the Internal Link Analyzer to see which pages have broken inbound link paths across your site.
Common HTTP Status Codes Reference
A quick reference for the status codes you'll encounter most often:
- 200 OK — page loaded successfully. The ideal response for all indexable pages.
- 301 Moved Permanently — page permanently moved to a new URL. Passes full link equity. Use for permanent URL changes.
- 302 Found — temporary redirect. Does not fully transfer SEO value. Use only for genuinely temporary moves.
- 307 / 308 — temporary / permanent redirect that preserves the HTTP method. Functionally similar to 302 / 301 for SEO.
- 403 Forbidden — server refuses access. Check file permissions and server configuration.
- 404 Not Found — page does not exist. Set up 301 redirects for pages with backlinks or traffic.
- 410 Gone — page permanently removed. Stronger deindex signal than 404.
- 500 Internal Server Error — generic server failure. Investigate server logs immediately.
- 502 Bad Gateway — upstream server returned an invalid response. Often a hosting or proxy issue.
- 503 Service Unavailable — server temporarily down. Use during maintenance with a Retry-After header.
To check whether your pages have correct meta tags after confirming they return 200, use the Meta Tag Checker or the Open Graph Checker.
HTTP Status Code Checker: FAQ
What is an HTTP status code?
An HTTP status code is a three-digit number returned by a web server in response to a browser or crawler request. It tells the client whether the request succeeded, failed, or requires further action. Status codes are grouped into five classes: 1xx (informational), 2xx (success), 3xx (redirection), 4xx (client error), and 5xx (server error).
What does a 200 status code mean?
200 OK means the server successfully processed the request and returned the requested content. This is the ideal status code for all your important pages. It tells search engines that the page exists, is accessible, and can be indexed.
What is the difference between a 301 and 302 redirect?
A 301 (Moved Permanently) tells search engines the page has permanently moved to a new URL and transfers ranking signals. A 302 (Found) signals a temporary move — search engines may keep indexing the original URL. For permanent URL changes, always use 301 to preserve SEO value.
What does a 404 status code mean?
404 Not Found means the server cannot find the requested page. It occurs when a page has been deleted, the URL was mistyped, or a link is broken. While a few 404s are normal, many 404 errors can waste crawl budget and create a poor user experience. Set up 301 redirects for deleted pages that had traffic or backlinks.
What does a 403 status code mean?
403 Forbidden means the server understood the request but refuses to authorize it. This typically happens when the page exists but access is restricted — by IP, authentication, or server configuration. Unlike 401, providing credentials will not help. Check your server permissions if important pages return 403.
What does a 410 status code mean?
410 Gone tells search engines that the page has been deliberately and permanently removed. Unlike 404, which implies the page might return, 410 is a clear signal to deindex the URL. Use 410 for pages you never want to bring back.
What does a 500 status code mean?
500 Internal Server Error is a generic server-side error. It means something went wrong on the server, but the server could not specify what. Common causes include misconfigured .htaccess files, PHP errors, exhausted memory limits, or database connection failures. Persistent 500 errors will cause search engines to drop your pages from results.
What does a 503 status code mean?
503 Service Unavailable means the server is temporarily unable to handle the request, usually due to maintenance or overload. When used correctly with a Retry-After header, search engines will come back later rather than deindexing the page. This is the correct status code to use during planned maintenance.
How many URLs can I check at once?
This tool supports up to 50 URLs per check. Enter one URL per line in the text area. All URLs are checked concurrently for fast results, with a real-time progress indicator as each URL completes.
Is this HTTP status code checker free?
Yes. This bulk HTTP status code checker is completely free with no signup, no limits on daily checks, and no ads. It is built for SEO professionals, developers, and website owners who need to quickly verify URL statuses.
