Why Monitor HTTP Status Codes?

Broken links and improper redirects actively harm your website's search engine optimization (SEO) and degrade user experience. Search engine bots like Googlebot rely on HTTP status codes (like 200 OK, 301 Moved Permanently, or 404 Not Found) to understand the structure and health of your site. Our Bulk HTTP Status Checker automates this monitoring for you.

1. Detect "Soft 404s" Automatically

A Soft 404 occurs when a webpage displays a "Not Found" message to users, but actually returns a 200 OK status code to search engines. This tells Google the page is perfectly fine, wasting your crawl budget and confusing search rankings. Our tool scans the HTML payload of every URL tested and uses heuristic analysis to accurately flag Soft 404s alongside standard network codes.

2. Validate Redirect Chains

Are your 301 and 302 redirects working properly? Redirect loops or broken redirect chains bleed link equity. By checking URLs in bulk, you can quickly audit site migrations, backlink profiles, or affiliate links to ensure traffic ends up exactly where it belongs.

3. High-Speed Bulk Processing (Up to 2,000 URLs)

Unlike traditional desktop crawlers that take hours to scan a list of URLs and consume your bandwidth, our cloud-native infrastructure checks up to 2,000 URLs concurrently per batch. Simply hit our async API endpoint, provide an optional webhook, and we will ping you when the entire batch is completed.

Questions

Frequently Asked Questions

What is a bulk HTTP status checker?
A bulk HTTP status checker is an SEO tool that allows you to upload or paste a large list of URLs and instantly retrieve the server response code (e.g., 200 OK, 301 Redirect, 404 Not Found, 500 Server Error) for all of them simultaneously. This is essential for auditing backlinks, site migrations, and finding broken links at scale.
What is a Soft 404 and how do you detect it?
A Soft 404 happens when a webpage returns a '200 OK' success code to search engines, but visually displays a "Page Not Found" message or empty page to users. This wastes Google's crawl budget. Our tool downloads the HTML of the page and uses heuristics to detect standard "not found" footprints even if the server claims the page is perfectly fine.
How many URLs can I check at once?
You can submit batches of up to 2,000 URLs per API request or via the dashboard Workspace. Our cloud workers process them in parallel in the background, allowing you to check tens of thousands of URLs daily without throttling your local network.
Do you follow redirect chains?
Yes. When checking a URL, our HTTP client follows redirects up to 5 times. We will return the final destination URL's status code, allowing you to easily identify broken redirect chains and infinite redirect loops.
