HTTP Status Checker

Alright, so you're probably wondering what all these HTTP status codes mean and why you should care. Here's the deal - every time someone (or a search engine bot) tries to access a page on your website, the server sends back a status code. Think of it as your website's way of saying "hey, everything's cool" or "oops, something's broken here."

Our HTTP status checker tool is like having a watchdog that monitors all your URLs and tells you exactly which ones are working perfectly and which ones are causing problems. And trust me, broken links can seriously tank your SEO rankings and frustrate the heck out of your visitors.

Understanding the Most Common HTTP Status Codes

Let's break down what these numbers actually mean. A 200 status code is the holy grail - it means everything loaded perfectly. When you see that green 200, you can breathe easy because that URL is working exactly as it should.

Now, 301 and 302 redirects are a bit different. A 301 is a permanent redirect (like when you've moved a page forever), while a 302 is temporary. This tool follows a redirect automatically and reports where it actually ends up — if you need to see every hop along the way (useful for spotting loops or unnecessary chains), our Redirect Checker is built for exactly that.

The 404 error means the page doesn't exist at that URL — usually because it was deleted, moved, or mistyped. A handful of 404s on any active site is normal; it becomes a real problem at volume, especially when Google's crawlers keep hitting the same broken links repeatedly. See our full 404 error guide for causes, fixes, and the nuance on when a 404 is nothing to worry about.

And then there's 500 series errors - these are server errors that mean something went wrong on the backend rather than with the URL itself. A 500 is often a generic application failure, while a 503 specifically means the server is temporarily unavailable (overloaded or under maintenance) and may resolve on its own. See our HTTP 500 error guide and 503 status code guide for the details.

How Our Website Crawler Works

Here's where things get really cool. You know how most URL checkers make you manually paste in every single URL? Yeah, that's tedious as hell. That's why we built a website crawler right into this tool.

Just enter your homepage URL, click "Extract URLs," and our crawler goes to work. It fetches your robots.txt file, finds your sitemap URLs, and discovers every page listed in them automatically (up to 500). We even handle nested sitemaps - you know, those sitemap index files that link to other sitemaps. This relies on your sitemap actually listing your pages, though - it's sitemap-based discovery, not an unrestricted crawler that follows every internal link, so anything missing from your sitemap won't show up this way.

And we're smart about filtering too. We automatically remove junk like RSS feeds, category pages, tag pages, and image files because let's be honest, you don't need to check the HTTP status of every single JPEG on your site. We focus on what matters - your actual content pages.

Bulk HTTP Status Checking for Large Websites

Got a website with hundreds of pages? Our bulk URL checker can handle up to 500 unique URLs in a single scan. Once you've extracted your URLs using the crawler, just hit the "Check Status Codes" button and we'll verify all of them.

We check them in small sequential batches (10 at a time) rather than firing every request at once, so a large scan stays within its own rate limit instead of failing partway through. Each result shows you the original URL, the final URL (if there was a redirect), the status code, and whether it's working, broken, or needs a closer look.

Why You Need Regular Link Checking

Look, websites aren't static things. Content gets updated, pages get moved, external links break, server configurations change. What was working perfectly last month might be throwing 404 errors today. That's why regular link checking is crucial.

A site that accumulates broken internal links without anyone noticing tends to have a rougher time getting fresh content crawled and indexed promptly. Running a status code check regularly is how you catch that before it becomes a pattern instead of an occasional 404.

Not Every 4xx or 5xx Means "Broken"

It's tempting to treat every non-200 result as a dead link, but that's not quite accurate. A 401 or 403 often means the page is intentionally protected — login-gated or blocking automated requests — not actually gone; see our 401 vs 403 guide for the exact distinction. A 429 means the target is temporarily rate-limiting requests, which can clear up on its own. And a 5xx can be a transient server hiccup rather than a permanent failure. That's why this tool separates confirmed-broken results (404, 410) from ones that need a closer look instead of lumping everything non-200 together.

How This Relates to Crawling and SEO

HTTP status codes are part of how Google's crawlers decide where to spend their attention. A single clean 404 for a page that's genuinely gone is a normal, expected signal — not a penalty trigger. What actually costs crawl attention is a large, uncorrected volume of broken links or redirect chains that crawlers keep running into on an ongoing basis. See our full HTTP status codes guide for the complete picture, including how each status range behaves and what's actually worth fixing first.

Broken links also create orphan pages that can't be reached through normal navigation — even great content on those pages won't rank if nothing points to it anymore. Our Broken Links Checker helps you find those before they become invisible.

Download Your Results as CSV

After running your bulk status check, you can download all the results as a CSV file. This is super handy if you need to share the report with your team, keep records of your site health over time, or import the data into other tools for further analysis. Just click the "Download CSV" button and you're good to go.

Best Practices for Maintaining Healthy URLs

First off, run this check at least once a month. Set a reminder, make it part of your routine. Second, when you find broken links, fix them immediately. Either restore the missing content, set up proper 301 redirects, or remove the links entirely.

For redirects, try to minimize redirect chains. If page A redirects to page B which redirects to page C, that's inefficient. Use our Redirect Checker to trace the full hop-by-hop path for a single URL, then update your links to point directly to the final destination, then use the Internal Linking Assistant to find other relevant source passages for that page. Your site will load faster and search engines will reach the intended URL directly.

Combine This with Other SEO Tools

Want to level up your SEO game? Use this tool alongside our SEO Audit tool to get a complete picture of your site's health. While this tool focuses on link status and redirects, the SEO Audit checks things like page speed, meta tags, and Core Web Vitals. Together, they give you everything you need to optimize your website.

Also check out our Broken Links Checker which digs even deeper by analyzing the HTML of each page to find broken external links. It's like having a full technical SEO suite at your fingertips - and it's all completely free.

Once your priority URLs are returning clean 200 status codes, the next question is whether Google has actually indexed them. Run those same URLs through the Google Index Checker to see if they're appearing in search results.

Stop letting broken links and server errors go unnoticed. Use our free HTTP status checker now to scan up to 500 URLs, identify issues, and get actionable insights in minutes.
