404 Quick Check
What it does
Tests a single URL and returns HTTP status code, redirect chain, response time and detailed error message — perfect for quick troubleshooting when you suspect a specific link is broken.
You suspect a link is broken, but do not have a quick tool to verify it without opening the browser and clicking manually
Dead links are one of the most common and overlooked SEO problems. When a user clicks a link and gets a 404 page, you lose both trust and potential conversions. But checking individual links manually is surprisingly cumbersome — you have to open the browser, navigate to the URL, interpret the error message and check if a redirect is involved. For developers and SEO specialists who work with hundreds of links daily, this is an enormous time thief.
- Manual checking is slow — you have to open the browser, wait for loading, and interpret the result for every single URL you want to verify
- Redirects are invisible — the browser follows redirects automatically, so you do not see if a link gøs through 2-3 redirects before reaching the destination
- Status codes are hidden — the browser does not show you whether it is a 301, 302, 307 or 404 — information that is critical for SEO decisions
- No context — when something fails you do not know if it is a server error, DNS problem, SSL error or that the page is actually removed
Get complete status information for any URL in under one second — including redirect chain and response time
404 Quick Check tests a URL and returns all information you need to diagnose the problem: HTTP status code, complete redirect chain, response time, SSL status and detailed error message. All in under one second, without leaving the platform.
- Instant status code: get the HTTP status code (200, 301, 302, 404, 500 etc.) immediately — no interpretation needed
- Redirect chain: shows the entire redirect chain from start to finish — so you see if the link gøs through unnecessary intermediate steps that slow performance
- Response time: measures how long the server takes to respond — so you can identify slow pages that affect user experience
- Detailed error message: when something fails you get a clear explanation of what went wrong — DNS error, SSL problem, timeout or actual 404
Features
- Batch mode: paste multiple URLs (one per line) to check up to 10 links simultaneously — perfect when you have a short list you want to verify quickly
- Header inspection: shows important HTTP headers like Cache-Control, Content-Type and X-Robots-Tag — useful for troubleshooting indexing problems
- History: saves your last 50 checks so you can go back and compare results over time — useful for tracking whether a fix actually worked
- Copy as report: export the result as a formatted report you can share with developers or clients — including all technical details
How it works
- Paste the URL you want to check — the tool sends an HTTP request and analyzes the response complete with status code, headers and redirects
- Get the result in under one second — status code, redirect chain, response time and any error messages are displayed immediately
- Use the information to diagnose and fix the problem — or share the report with the development team for quick bug fixing
Use cases
- SEO specialists — quickly verify if a reported dead link is actually broken, and get technical details to communicate the fix to developers
- Developers — troubleshoot redirect chains and server responses without using curl or browser developer tools
- Content producers — check that external links in your articles still work before you publish or update content
Why use 404 Quick Check?
Speed in troubleshooting. When someone reports a dead link — whether it is a colleague, a client or a monitoring tool — you need the answer now. Not in five minutes after you have opened the browser, navigated to the URL and tried to interpret what happened. 404 Quick Check gives you the answer in under one second, with all the technical context you need to act.
Redirects are SEO-critical. A link that goes through 3-4 redirects before reaching the destination loses link equity at each step. 404 Quick Check reveals these hidden redirect chains so you can simplify them and preserve maximum SEO value.
Professional communication. When you report a link problem to developers or clients, "the link does not work" is not enough information. With 404 Quick Check you can say exactly what the status code is, where the redirect fails and what the response time is — which makes bug fixing faster and more precise.
FAQ
- What is the difference between this and Broken Link Hunter?
- 404 Quick Check checks individual URLs quickly — perfect for troubleshooting specific links. Broken Link Hunter crawls your entire website and finds all dead links automatically. Use Quick Check for quick verification and Hunter for complete site analysis.
- Can the tool check links behind login?
- No. The tool sends standard HTTP requests without authentication. Links that require login will return a 401 or 403 status code, which in itself is useful information for identifying access problems.
- Why does the tool show a different status code than the browser?
- The browser follows redirects automatically and shows you the final page. The tool shows the first status code in the chain (e.g. 301) plus the entire redirect chain. This gives you more precise information about what is actually happening behind the scenes.
- Can I check if a page is indexed in Google?
- The tool checks HTTP headers including X-Robots-Tag which can indicate if a page is blocked from indexing. For complete indexing checks we recommend using Google Search Console or a dedicated indexing tool.
