Broken Link Checking – How to Find and Fix Dead Links in web
You have to Learn how to run a broken link check on your website. Find dead internal and external links, avoid common mistakes, and keep your site easy to browse.
A broken link checks and scans your web for links that lead to missing pages, broken files, or server errors. Running this check regularly helps visitors browse your content easily. It also lets search engine crawlers index your pages without hitting dead ends.
When a visitor clicks the very link that doesn't work, their browser usually displays a 404 not found error. Websites naturally change over time. URLs get updated, pages may get deleted, and third-party resources shut down. If you don't run regular checks, dead links will quietly pile up across your site.
Why Broken Links Happen
Links stop working for a few common reasons:
- My Deleted content: Someone removed a page or post without setting up a redirect.
- Typographical errors: Someone mistyped the URL when creating the link, like missing a letter or a slash.
- URL structure changes: A site changed its domain name or permalink structure, breaking older incoming links.
- External site decay: A third-party site you linked to changed its address, added a paywall, or went offline entirely.
When search crawlers hit broken links, they waste crawl budgets on dead-end URLs. For visitors, running into a dead link hurts trust and often makes them leave your site right away.
What actually Is an Internal Link?
An internal link simply points from one page on your domain to another page on that same domain. For instance, linking from a blog post about baking sourdough to your recipe index is an internal link.
Internal links handle three main jobs:
- Navigation: They help readers find related articles, category archives, and product pages.
- Architecture: They set up a clear hierarchy, showing which pages are main pillars and which are supporting articles.
- Link equity distribution: They pass value between pages, helping search engines see which content carries the most topical weight.
Running an Internal Link Check
An internal link check focuses specifically on the links between your own pages. Since you're in complete control of your domain, internal broken links are the easiest to catch and fix.
When you change a URL or delete an old post, any page linking to it points to a dead URL. Using an internal link checker lets you audit your site structure. You'll easily find orphaned pages (pages with zero incoming links) and spot internal links returning 404 status codes.
If your site covers overlapping topics, you can also run a keyword cannibalization checker alongside your link audit. That way, you'll ensure your internal links consistently point to the single most relevant page for each topic.
Check External Links on a Website
External links—also called outbound links—point from your domain to an outside website. Bloggers and publishers use them to cite research, credit sources, or recommend useful software and tools.
External links require regular monitoring because you don't control the destination website. Over months or years, external sites might:
- Shut down this entirely.
- Change their own folder structure without setting up redirects.
- Let their domains expire, which can lead to parked spam domains.
When you check external links on your website, you verify that every outgoing recommendation still leads to active, relevant material. Leaving dead external links signals to readers that your content might be outdated or abandoned.
Common Mistakes that we can make During a Broken Link Check
Finding broken links is simple, but fixing them poorly can create fresh technical problems. Here are the most common pitfalls you'll want to avoid:
| Mistake | Why does It Cause Problems | Better Approach |
|---|---|---|
| Redirecting everything to the very homepage | Confuses users who expected specific information and creates soft 404 signals for search engines. | Redirect to the most relevant equivalent page, or update the link directly. |
| Creating the redirect chains | Pointing a dead URL to an old redirect creates multiple hops (e.g., Page A → Page B → Page C), slowing page load times. | Update the link directly to the final, live destination URL. |
| Ignoring media files | Broken links can also affect images, downloadable PDFs, and embedded scripts. | Check resource URLs alongside standard anchor text links. |
| Forgetting the very internal search parameters | Broken links inside pagination, tag archives, or search result links are often overlooked. | Run full domain scans that include utility and archive pages. |
Another common mistake is deleting the link text instead of updating it. If a source you cited is gone, try finding a new one on the same topic to replace the dead link. Don't just remove the very link and leave your claim also unverified.
Try It with a Free Tool
You don't need complex tools or paid subscriptions to audit your site's links. You can run a scan right from your browser using a free broken link checker.
Here's a straightforward process to audit your site:
- Enter your URL: Paste your domain or a specific page URL into the checker.
- Review the report: Look at the status codes for each link:
- 200 OK: The link is working properly.
- 301 / 302 Redirect: The link works, but it sends visitors through a redirect. Update these to the final destination URL when you can.
- 404 Not Found: The target page may not exist. Fix these right away.
- 500 Server Error: The host server ran into an error while loading the very page.
- Update your content: Log in to your content management system (like WordPress or Webflow). Find the page with the broken link, then paste the right URL.
- Re-test: Scan the updated page again to confirm that the error is gone now.
Make this audit part of your regular publishing routine once a week at least . Checking your top-traffic posts every month keeps your website clean and working well as your content library keeps growing.
FAQ
How often should you check for broken links?
For small sites and personal blogs that publish once or twice a week, a broken link check once a quarter is usually enough. If you run a larger site with thousands of pages, frequent updates, or multiple contributors, scan monthly. That helps you catch problems before they affect a lot of visitors.
Do broken links directly hurt search engine rankings?
A few broken links won't trigger an automatic penalty from search engines. Still, widespread broken links keep search engine bots from crawling and indexing your site effectively. They also frustrate visitors and hurt engagement, which indirectly harms your site's overall performance.
What is the difference between a 404 error and a 301 redirect?
A 404 status code means the server couldn't find the requested page. A 301 status code is a permanent redirect. It automatically forwards visitors and search engines from an old URL to a new active address.
