Bulk HTTP Status Code & Redirect Chain Checker

What does Bulk HTTP Status Code & Redirect Chain Checker do?

This Actor checks the HTTP status code and the full redirect chain of up to 100,000 URLs in one run. For every URL you get the first status code, every redirect hop, the final URL and its status code, plus issue codes for the problems that hurt SEO and users.

It also verifies redirect maps after a website relaunch: paste lines like old URL -> new URL and see at a glance which redirects land on the wrong page.

No proxies and no browser, so runs are fast and cheap.

Why use this HTTP status checker?

• Find broken URLs (404, 410, 500) in lists from Google Search Console, sitemaps, backlink tools or old exports
• Check every redirect hop: redirect chains waste crawl budget and slow down users
• Catch 302 instead of 301: temporary redirects don't pass rankings reliably
• Detect redirect loops and URLs with too many redirects
• Make sure http:// redirects to https://
• Website relaunch / migration: check hundreds of old URLs against their expected new targets
• Monitor link lists on a schedule and export to Google Sheets, Excel or CSV
• Pay per URL: URLs that can't be reached at all are free

What does it check?

Issue code	Meaning
INVALID_REDIRECT	A redirect status (301, 302, …) without a valid Location header
CLIENT_ERROR	Final status is 4xx (404 not found, 410 gone, 403 forbidden, …)
SERVER_ERROR	Final status is 5xx
REDIRECT_CHAIN	More than one redirect before the final page
REDIRECT_LOOP	The chain leads back to a URL it already visited
TOO_MANY_REDIRECTS	More than 10 redirects
TEMPORARY_REDIRECT	A 302, 303 or 307 redirect in the chain instead of 301 or 308
HTTP_TO_HTTPS_MISSING	An http:// URL does not end on https://
WRONG_TARGET	Redirect map only: the final URL is not the expected target
UNREACHABLE	No HTTP response at all (DNS error, timeout, connection refused). Not charged
INVALID_URL	The input line is not a valid URL. Not charged

What data does it return?

Field	Description
url	Checked URL
statusCode	Status code of the first response
finalUrl, finalStatusCode	Where the chain ends
redirectCount	Number of redirects followed
redirectChain	Every hop with url, statusCode and location
responseTimeMs	Total time for the whole chain
contentType	Content type of the final response
expectedUrl, matchesExpected	Redirect map only
issues	Issue codes, see above
error	Network error, if no response was received

A Summary (key-value store record SUMMARY) counts all URLs by final status code and by issue.

FAQ

Why HEAD requests?

HEAD asks only for the headers, so checks are fast and light on the server. Some servers answer HEAD with a wrong error code, so every error response is double-checked with a GET request. Choose GET if you want only GET requests.

Does it run JavaScript redirects?

No. It follows HTTP redirects (301, 302, 303, 307, 308), like search engines do on the first pass. Redirects done with JavaScript or <meta http-equiv="refresh"> are not followed.

Some sites return 403 for every URL

Some firewalls (for example Cloudflare bot protection) block automated requests. The 403 is then what bots see, not what browsers see. Try another User agent in the advanced options.

Will it overload a server?

It uses 10 parallel requests by default. If all URLs are on one small server, lower Parallel requests.
