Best Dead Link Checkers to Keep Your Site Error-Free

Dead links can cripple a site’s user experience and undermine its credibility.

I’ve learned that when search engines see these broken links pile up, they aren’t happy, nor are your visitors.

Manually hunting down faulty URLs on a mid-to-large site is like searching for a bent needle in a haystack. Fortunately, there is a set of tools available to ease the task.

In this post, I’ll share my personal top 9 dead link checker tools. Along the way, I’ll explain how each tool helps with technical SEO, why it is useful, and which tasks it handles well.

My aim is to simplify your decision so you do not end up with several partial solutions that complicate your workflow. 

Here is a simplified overview of the tools in the list:

Why Dead Links Grate on Your SEO

I have spent countless hours performing SEO audits and know firsthand that broken links can:

• Frustrate site visitors
• Disrupt your internal linking structure
• Send negative signals to search engines about overall site maintenance

These are serious issues. If you manage a rapidly growing site or a large e-commerce store, broken links are almost inevitable.

With the right dead link checker, however, you can locate and fix them in an afternoon instead of over several weeks.

Technical SEO is challenging enough, so it is best to simplify this process.

The Importance of Automated Dead Link Checkers

Manually checking each page wastes time and can lead to mistakes. I rely on automated tools that:

1. Crawl your entire site (or a single webpage).
2. Identify links that produce 404 errors, timeouts, or routing loops.
3. Generate easy-to-read reports so you can fix or redirect them as needed.

The simplicity is appealing. Most of these tools also categorize link issues by type, allowing you to prioritize fixes based on severity or frequency.

1. SEO.AI

I’m working at SEO.AI, so it may come as no surprise that I’m recommending it but even so, I still find it to be one of the best platforms out there for optimizing your content, from meta descriptions to product feeds.

Built around AI that focuses on SEO, it’s ranked as the #1 platform for AI SEO and helps you write and optimize everything so it appeals to both customers and search engine algorithms.

Why SEO.AI Stands Out

• Offers an AI SEO assistant for generating and refining content.
• Provides data-driven insights to align with Google’s algorithm.
• Built-in AI Chat for streamlined editing and collaboration.
• Integrates easily with Google Merchant Center, Search Console, Shopify, WordPress, and more.

Beyond just helping with broken link strategies, SEO.AI’s real value lies in its ability to create and optimize content in a brand-consistent voice, measure performance across webpages and product feeds, and automate large-scale tasks like meta descriptions. If you’re looking to handle both content quality and link auditing in one platform, SEO.AI offers a powerful suite of tools.

2. Google Search Console

I often use Google Search Console first because it is free and already connected to my sites. Although it does not call itself a “broken link checker,” it alerts you about pages that have crawling or indexing errors, some of which come from dead or broken links.

Here’s why I find it useful:

1. It is straightforward to set up.
2. You get direct data from Google’s index.
3. Error reports can reveal issues beyond broken links, such as server errors.

3. Dead Link Checker

Dead Link Checker is a tool dedicated to detecting dead links. I like that it makes the process very simple. You can start a scan, and the tool provides a report that shows non-functional URLs. Since it is web-based, there is no need to install any software.

Why It Matters

• Straightforward interface.
• Options for checking a single page or an entire site.
• Offers scheduling for regular link audits (with the paid plan).

4. Broken Link Checker (WordPress Plugin)

If you work a lot in WordPress, you have probably heard of the Broken Link Checker plugin. It is something I install frequently on new WordPress projects that require frequent content updates. It scans your site for broken links, usually running automatically, and flags them directly within the WordPress admin panel.

Highlights

• Real-time scans that run in the background.
• Allows quick editing or removal of dead URLs from a central dashboard.
• Free and well-maintained.

5. Screaming Frog

For those who prefer more advanced SEO analysis, Screaming Frog is a reliable tool. I run a crawl on my site, which reviews pages, images, CSS, and scripts, then reports any errors or issues, including broken links.

Features I Like

• Desktop-based tool with deep crawling abilities.
• Exports data in CSV or XLS, making sharing or integrating with other reports easy.
• Integrates with Google Analytics and Search Console for added data.

6. SEMrush

SEMrush offers much more than checking for dead links, but I find its Site Audit tool a trustworthy resource for detecting them. If you are already using SEMrush for keyword research or competitor analysis, you will appreciate that its broken link detection is part of a broader SEO toolkit.

Why It Stands Out

• Detailed site crawl with automatic issue categorization.
• Provides suggestions on how to fix each type of error.
• Monitors your site’s overall health score.

7. Ahrefs

Ahrefs is another popular all-in-one tool among SEO professionals. Its Site Audit feature scans your URLs and finds dead links, along with data on backlinks, anchor text, and more. I appreciate that it separates link errors into clear categories, which makes prioritizing fixes easier.

Key Advantages

• In-depth backlink analysis (useful for external link repair efforts).
• User-friendly interface with color-coded issue severity.
• Regular recrawls for ongoing monitoring.

8. Dr. Link Check

Dr. Link Check focuses on dead links, suspicious links, and SSL certificate issues. I appreciate its focus on security—beyond basic broken link checks, it flags links to sites with poor reputations.

Dr. Link Check Specialties

• Categorizes issues as “Dead,” “Parked,” or “Malware.”
• Sends automated email reports when new issues appear.
• Offers a free plan for small sites.

9. Xenu’s Link Sleuth

An old-school yet reliable free tool, Xenu’s Link Sleuth remains popular with veteran SEOs. It is Windows-based, with a basic interface. Despite its age, I find it surprisingly effective for large-scale crawls, especially when you simply need to spot broken links and check for server errors.

Strengths

• Manages large websites with few issues.
• Free to download and use for unlimited scans.
• Reports are clear once you get familiar with the interface.

Comparison Table

Below is a snapshot of how these nine tools compare on key aspects. Keep in mind that some features may vary by plan or software version.

Choosing the Right Tool for Your Needs

How do you choose one? Here are a few guidelines I have learned over time:

1. Budget and Frequency
   • If you only need occasional checks, a free or one-time purchase tool might be enough.
   • If you conduct audits daily or weekly across multiple domains, consider a subscription-based tool or robust desktop software.
2. Integration with Your Existing Workflow
   • Already using SEMrush for keyword tracking? Rely on its site audit for dead links.
   • Prefer working directly in WordPress? The Broken Link Checker plugin is a natural fit.
   • Need data integrated from Google? Google Search Console or a tool that works with it may be best.
3. Size and Complexity of Your Site
   • Smaller sites (up to a few hundred pages) can get quick results with free, web-based checkers.
   • Larger sites with thousands of pages require a more powerful crawler like Screaming Frog or Xenu’s Link Sleuth.

In my experience, I usually use more than one tool. For example, I might start with a quick pass using Dead Link Checker and then run a detailed crawl with Screaming Frog for further analysis.

My Personal Workflow (An Example)

Sometimes I get asked how I handle link audits. Here is a rough outline:

1. Check Google Search Console
   • Look for glaring 404 errors or server issues.
   • Note which URLs are affected.
2. Run Screaming Frog
   • Crawl the site to confirm or uncover additional broken links.
   • Export the broken link report.
3. Use a WordPress Plugin (if applicable)
   • On WordPress sites, quickly fix or remove problematic links in bulk.
4. Confirm Fixes
   • Re-run Screaming Frog or another crawler to ensure the 404s are resolved.
   • Check Search Console to see if the errors have cleared after the next update.

This approach of using multiple tools might seem excessive for smaller sites, but for larger ones with many contributors and frequent updates, it has saved me from serious issues more than once.

Addressing Dead Links Beyond Just Fixing Them

You might think, “Alright, I’ve found my dead links—time to fix them, done.” Consider turning them into opportunities through broken link building, an advanced SEO method. When external sites link to outdated pages on other domains, you can offer them an updated resource from your site. In return, they might update their link to point to you.

I have had success with this tactic using Ahrefs. I locate pages on competitor sites that result in a 404 and then contact the webmasters with my own well-organized content. It does not always result in a link, but it is a useful approach.

FAQ

What are dead link checkers?

Dead link checkers are tools designed to identify broken or non-functional links on a website. These tools help maintain the integrity of a website by ensuring that all links direct users to active and relevant pages.

Dead link checkers scan a website's pages and analyze each link to determine if it leads to a valid destination. If a link is broken, the tool will typically provide details about the error, such as a 404 status code, and identify the page where the broken link is located.

Can dead link checkers fix broken links automatically?

Most dead link checkers do not fix broken links automatically. They identify and report the issues, allowing website administrators to manually update or remove the problematic links to ensure proper functionality.
