Broken Links: Why They Hurt Your Site & How to Fix Them for Good

Ever clicked a link only to land on a “404 Page Not Found” error? Frustrating, isn’t it? As a marketing expert with 25 years in the business, I’ve seen how broken links can quietly sabotage even the best websites.

In fact, over 42% of websites have broken links lurking on them. These dead links not only irritate your visitors – they can also hurt your SEO, credibility, and conversions. The good news? You can tackle broken links head-on.

This comprehensive guide will show why broken links are a problem, how to find and fix them, and how to prevent “link rot” from undermining your site’s success. Let’s dive in and turn those 404s into opportunities!

What Are Broken Links (Dead Links)?

Broken links (also known as dead links or “link rot”) are hyperlinks that fail to lead you to the intended webpage. Instead of the content you expected, you’re met with an error or an empty page. The most common example is the infamous “404 Not Found” error – indicating the page no longer exists on the server.

Broken links can occur as internal links (pointing to pages within your own website) or external outbound links (pointing to other websites). In both cases, the result is the same: the link goes nowhere.

Realistically, a broken link can trigger various error messages. For instance, a broken URL might return a 404 Page Not Found (the page doesn’t exist), a 400 Bad Request (malformed URL), an Invalid Hostname (domain doesn’t exist), or other errors. No matter the technical code, a broken link means a dead end for the user.

Why do links break?

Over time, web content moves or disappears. A page you linked to last year might be deleted or relocated today (without a redirect). Maybe a URL was typed incorrectly, or an entire domain expired. This natural decay of hyperlinks over time is often called “link rot” – links “rotting” away as their targets change or vanish. It’s an unfortunate reality of the ever-evolving web.

Why Broken Links Are a Big Problem

Broken links aren’t just a minor annoyance – they can actively hurt your website’s performance and reputation. Here’s why every website owner should care about fixing dead links:

• Poor User Experience: First and foremost, broken links are frustrating to your visitors. If someone clicks a link expecting useful content and hits a dead end, it’s a disappointment. Users may lose trust in your site and leave in search of information elsewhere.One or two broken links might be forgiven, but if your site feels littered with them, visitors may not return. Simply put, a link that leads nowhere is worse than no link at all.
• Lost Opportunities and Conversions: If an internal link on your site is broken, you’re missing the chance to engage that visitor further.For example, if a blog post links to a product page that no longer exists, you lose a potential sale or lead. Even broken outbound links can send someone off your site in frustration – definitely not what you’re aiming for!
• Damage to Credibility and Reputation: Broken links make your site look neglected or unprofessional. Many visitors perceive multiple dead links as a sign of poor maintenance or even “disrespect”. It suggests you’re not keeping your content updated.This can hurt your brand’s credibility. In fact, Google’s own quality raters use the presence of broken links as a factor when assessing the quality of a website. A site riddled with dead links might be seen as lower quality or abandoned.
• SEO Impact – Crawling and Indexing: Broken links can quietly undermine your SEO efforts. How? For one, they waste your crawl budget. Search engine bots like Googlebot have a limited number of pages they’ll crawl on your site.Every time they hit a 404 error page via a broken link, it’s a wasted crawl that could have gone to a valid page. Too many broken links and Google’s crawlers might begin to crawl your site less efficiently.

  Moreover, if important pages on your site aren’t reachable (because internal links to them are broken), those pages might get dropped from search indexes over time.

• SEO Impact – Loss of Link Equity: Broken links can also leak or lose “link juice” (SEO equity). For example, if you have an internal link from one page to another but it’s broken, the receiving page gets no SEO benefit from that link.Likewise, if other websites are linking to a page on your site that no longer exists (a broken inbound link), you’re not getting any of the ranking benefit from those backlinks. All the authority that those links carried is essentially wasted. Fixing broken links ensures that both your internal linking strategy and external backlinks can pass value as intended.
• Higher Bounce Rates: Broken links can contribute to visitors quickly leaving your site (bouncing). If a user hits a 404, many won’t take the time to dig around – they’ll just hit the back button and choose a different search result or website. Multiple dead links can therefore increase your bounce rate and lower the time users spend on your site, which are user engagement signals that can indirectly affect search rankings.
• Negative Effect on Rankings Over Time: While a few broken links won’t automatically tank your Google rankings (even huge sites like Apple.com have a handful), a pattern of many broken links can hurt. Google wants to send users to content that is up-to-date and well-maintained.If your site appears neglected (e.g. a “Top 10 Resources” article full of dead outbound links), it could be seen as lower quality or stale, potentially affecting your rankings.

  In short: broken links won’t trigger an SEO penalty per se, but they undermine the quality and effectiveness of your site, which in turn can harm your SEO performance.

• Pervasive Issue Even for Top Sites: You might think broken links only plague small or old websites, but even high-profile sites struggle with link rot. A 2023 analysis by Pew Research found that 23% of news website pages and 21% of government webpages contained at least one broken link.(And in Wikipedia, over half of the pages had a dead link in their references!) Broken links are a widespread problem, so addressing them is part of staying competitive with the best sites.
• Security Concerns: Here’s an often overlooked point – sometimes a “broken” link isn’t just an error, but something more nefarious. In some cases, an old external link that once was safe might later point to a compromised or malicious site (for example, if the linked domain expired and was taken over by someone else).That’s even worse than a normal 404. You don’t want your site sending users to malware or spam by accident. Regular link checks can catch these issues. As one tool provider notes, “even worse than a broken link is a link to a website that causes harm through malware or phishing.” Keeping links fresh isn’t just about SEO – it protects your users as well.

Bottom line: Broken links hurt user experience and SEO hand-in-hand. They frustrate real people and squander the trust and authority you’ve worked hard to build. Now that we’ve established why dead links are bad for business, let’s look at how they happen and what you can do about it.

What Causes Broken Links?

Understanding why links break can help you prevent them. Here are the most common causes of broken links:

• Deleted or Moved Content (No Redirect): This is the classic cause of a 404 error. You had a page at a certain URL, but then you removed it or moved it elsewhere, and didn’t set up a redirect. Now any link pointing to the old URL is broken.For example, you might delete an old blog post or product page, or change your URL structure (permalinks) during a website redesign. Without proper 301 redirects from the old URLs to the new destinations, those links become dead-ends.
• Typos and URL Formatting Errors: Sometimes the link was simply entered incorrectly. A misspelled filename, an extra slash or character, or the wrong domain suffix (.com vs .org, for example) will mean the link doesn’t work.These mistakes can creep in when content editors manually add links. A malformed URL (like missing http:// or a piece of the path) is another example of a broken link due to human error.
• External Page or Site Went Offline: When you link out to another website’s page, you have no control over how long that content stays up. The external site might remove the page or change its URL structure without notice. It might even shut down entirely or let its domain expire.Now your outbound link is pointing into the void. For instance, if you cited a statistic from an article on another site, and that article gets taken down, your link becomes broken. External link rot is very common because the web is constantly changing (think of how many news sites archive or remove old content).
• Embedded Content Was Removed: Similar to above, if you embedded an image, video, or other media from an external source, and that resource gets removed or moved, you’ll have a broken link (or broken embedded media). For example, an image hosted on a third-party server that gets deleted will show up as a broken image icon on your page.
• Changes in File Paths or Case Sensitivity: On some web servers (especially Linux-based), URL paths are case-sensitive. If you change the capitalization of a directory or file name, or move files around, previous URLs may break.This often affects images or downloadable files – e.g., if /Images/Pic.png moves to /images/pic.png, any old link to the capitalized path breaks.
• CMS or Plugin Issues: Sometimes broken links can be introduced by quirks in your Content Management System or plugins. For example, a faulty WordPress plugin might generate incorrect URLs (as seen in some cases where an extra “/link” was appended to URLs causing 404s).Dynamic content or database-driven links can go awry if the underlying item is removed. If your site software isn’t managing URL changes properly, broken links can proliferate.
• Outdated References: If you have an old article listing resources or linking to sites that were relevant years ago, some of those references might now be outdated or gone. For instance, a blog post from 2015 linking to a tool or report might be full of broken external links by 2025, simply because things have changed or moved.
• Firewall or Geolocation Blocks: In some cases, a link may appear “broken” to certain users if the target site is blocking access. For example, a site might block visitors from certain countries or have firewall rules that make it unreachable to your link-checking tool.While the content might exist, it’s effectively inaccessible (returning timeout or unauthorized errors). This is a less common scenario but worth mentioning – not all “broken link” reports mean the content is gone; sometimes it’s just not reachable due to permission issues.

In summary, broken links happen naturally over time as the web evolves. Your site grows, content moves, other sites change – and links get left pointing to the past. This “digital decay” is so common that a term like “link rot” exists to describe it. But while you can’t stop link rot from occurring, you can stay on top of it. Next, we’ll look at how to proactively find broken links on your website, before they cause too much trouble.

How to Find Broken Links on Your Website

If you’re wondering whether your site has broken links, the answer is probably “yes.” Virtually every site has a few. The key is to find and fix them regularly. Fortunately, you don’t have to click every link on every page manually – there are excellent tools to help discover dead links efficiently. Here are some of the best ways to detect broken links:

1. Run an SEO Crawler or Site Audit Tool

One of the most comprehensive methods is to use an SEO crawling tool or site audit tool. These tools will systematically scan your website (just like a search engine crawler would) and report any broken links or other errors they find.

Popular options include Ahrefs, SEMrush, Moz, Sitechecker, and many others. For example, Ahrefs’ Site Audit can be set to crawl your site and will list all broken URLs (404 errors) it encounters. SEO audit tools typically identify both broken internal links and broken external links on your site.

Using a professional tool is beneficial if you have a large site or want deeper insights. They often provide reports showing the broken link, where it was found (which page is linking to it), and sometimes suggestions for fixes.

Many of these are paid services, but if you already invest in SEO software, make use of the site auditing features. As an example, Ahrefs, SEMrush, and Sitechecker all have robust crawlers that make finding broken links a breeze. These can save you hours that would be spent manually combing through pages.

(Pro tip: Some SEO tools also help you find broken backlinks – i.e. other sites linking to your broken pages. We’ll discuss this more later, but keep in mind that finding broken inbound links is another angle to consider.)

2. Check Google Search Console (for Internal 404s)

Google Search Console is a free tool from Google that every site owner should use. It won’t exactly “crawl” your site on demand for broken links, but it will report issues Google’s own crawlers encounter on your site.

In particular, Search Console has a Coverage or Pages report under the Indexing section, which includes a list of pages that returned errors (such as 404 Not Found) when Google tried to crawl them.

These error pages often indicate broken links somewhere on your site. For example, if pageA has a broken link to pageB, Google might list pageB as “Not found (404)” in Search Console, and when you inspect it, it will show the referring page (pageA) that linked to it. This helps you pinpoint which internal link needs fixing.

To use this: go to Search Console, under Indexing > Pages, look at the section for errors (404 not found). Click on each URL error and check the details – Google will often list “Referring page” – i.e., the page that has a link to the 404. That’s where you should fix the link.

Keep in mind, Search Console will only show internal broken pages (it doesn’t report external outbound broken links). And it might not catch everything if Google hasn’t crawled recently. But it’s a great starting point and prioritization tool (Google will flag what it thinks are the most important issues).

If the top errors shown are trivial or irrelevant, you can be somewhat assured there are no critical broken link issues. But don’t rely on GSC alone – use it alongside other methods.

3. Use a Desktop Crawler (e.g. Screaming Frog)

For a hands-on approach, desktop software crawlers are extremely effective for finding broken links. The most popular is Screaming Frog SEO Spider, which is a program you can install on your computer (available for Windows, Mac, Linux).

Screaming Frog will crawl up to 500 URLs for free (and more with a paid license) and provide a detailed breakdown of your site’s links. It’s widely used by SEO professionals for site audits.

To find broken links with Screaming Frog, you simply enter your website URL as the starting point and hit Start. Once the crawl is done, you can filter by response codes to see which URLs returned 4xx errors (like 404).

The tool will list those broken URLs and importantly, show you which pages on your site link to them (this is in the Inlinks tab). This way, you know exactly where to go to fix the broken link. Screaming Frog will catch broken internal links and can also report broken external links that your pages link out to.

Other desktop tools exist (for example, Integrity for Mac is another free link checker), but Screaming Frog is considered the gold standard.

The advantage of a desktop crawler is you have a lot of control – you can crawl behind login if needed, set ignore rules, etc.

The disadvantage is it uses your machine’s resources and might be slower for very large sites (in which case a cloud-based crawler or splitting the job might help).

4. Try an Online Broken Link Checker (Web-Based Tools)

If you have a smaller site or want a quick check without installing anything, online broken link checker tools can do the job. These are web-based services where you input your website URL, and their servers crawl your site for broken links.

A popular free option is BrokenLinkCheck .com, which allows you to scan up to 3,000 pages for free. It will report a list of broken links it finds, including whether each broken URL is internal or external, and the page on which each broken link occurs.

Similarly, Dead Link Checker (deadlinkchecker. com) is another tool where you can either check a single page or a whole site. It will output a list of bad links found. (Dead Link Checker’s free version finds broken links on your pages, though note it might not list which external sites link to you – it just finds broken outgoing links.)

There are also more advanced paid tools like Dr. Link Check that not only find broken links but also check for issues like improper SSL, malicious content on target pages, etc.

Dr. Link Check lets you schedule regular scans and get email reports, which is great for ongoing monitoring. It emphasizes that it checks each link thoroughly and even catches “soft errors” (pages that return 200 OK but are actually error pages in content).

The upside of online tools: no setup required, often free for basic use, and platform-independent (works regardless of your OS). The downside: many have limits on number of pages or require registration for full features, and they might be slower or get blocked by your site’s firewall if abused. Still, for most small-to-medium sites, running a quick free broken link report online is an easy win.

Tip: When using a tool like BrokenLinkCheck .com, choose the option to report “all occurrences” of broken links (not just one instance). This way, if the same broken URL is linked from multiple pages, you’ll see each page that needs fixing. It can be more time-consuming, but it ensures you don’t miss anything.

5. Use a CMS Plugin or Extension (for Ongoing Monitoring)

If your website runs on a Content Management System like WordPress, you have the option to use a broken link checker plugin for continuous monitoring. One well-known tool is the Broken Link Checker plugin (originally by WPMU Dev).

This plugin will scan your WordPress site’s content for broken links and can even notify you via the dashboard or email when it finds new ones. It provides an interface where you can quickly edit or unlink the broken item right from the plugin screen, which is very convenient.

There is a caveat: the traditional Broken Link Checker plugin gained a reputation for being resource-intensive and potentially slowing down sites (since it would constantly crawl your content). However, it was taken over by a new developer and updated to offer a cloud-based scanning option.

The updated version offloads the heavy work to their cloud service, so it won’t bog down your website while checking. You can schedule scans (daily, weekly, monthly) and have reports sent to you or your webmaster automatically. This is a powerful “set it and forget it” solution to catch broken links early, before your visitors do.

If you prefer not to use the cloud, you can still run the plugin on-demand (and it’s wise to deactivate it when not in use to save resources). There are also alternative WP plugins like WP Broken Link Status Checker, which lets you manually run scans when needed and is lighter on performance (though it lacks automation).

Outside of WordPress, other CMS platforms might have similar tools or extensions. For example, some SEO plugins or services for platforms like Drupal, Joomla, etc., include link checking features. Depending on your setup, it can be worth exploring if an integrated solution exists – especially if you manage a lot of content and want continuous oversight.

6. Browser Extensions and Manual Spot-Checks

Finally, for quick manual checks of specific pages, you can use browser-based tools. There are free browser extensions such as Check My Links (for Google Chrome) which, when activated on a page, will highlight all the links and mark broken ones in red.

This is a handy way to verify a single page – for instance, if you’ve just updated a blog post and want to ensure all its outbound links are valid, run the extension and scan for any highlighted broken links.

Manual checking is obviously not feasible for an entire site on a regular basis, but it’s useful for spot-checking important pages or doing a sanity check after making content changes. Additionally, if your site has only a few pages, manually clicking through links or using a browser tool might suffice in lieu of a full crawler.

Don’t forget the simplest manual method: clicking around your own site as a user. Every so often, take the journey a visitor might: navigate menus, click older blog posts, try out sidebar links.

You might stumble on broken links that automated tools missed (for example, broken links in third-party widgets, or links that require a certain user state).

In summary, utilize a combination of the above methods for best coverage. For instance, you might run a Screaming Frog crawl monthly, keep Broken Link Checker plugin running in the cloud for continuous monitoring, and periodically check Google Search Console for any reported 404 errors. With these techniques, no broken link can hide for long.

How to Fix Broken Links (Step-by-Step)

Finding broken links is half the battle – now you need to fix them. The approach to fixing a broken link will depend on what kind of link it is and why it’s broken.

As a seasoned web optimizer, let me share a key principle: every broken link needs to be handled on a case-by-case basis. There’s no one-size-fits-all solution, because the “right” fix depends on the context. Below are best practices for addressing different types of broken links:

1. Fix Broken Internal Links by Updating or Removing the Link: If the broken link is on one of your pages and points to another page on your site (internal), you should ideally change the link at the source to point to the correct destination.For example, if you had a typo in the URL, correct the spelling. If the link was pointing to a page you moved, update it to the new URL. If the content no longer exists at all, you have a decision to make: either remove the link (and possibly the reference around it if it’s no longer relevant), or if you have a replacement piece of content that covers similar ground, link to that instead. The key is that users should no longer be led to a dead end.

   Sometimes, simply removing a broken link is the best option – especially if it’s not crucial to the user’s understanding. However, if the sentence or section only made sense with that link, you might need to update the content to accommodate a new link or new information.

   For instance, if you had a statistic cited with a link and that link broke, find a more recent statistic (and link) to replace it, or adjust the text. And if an internal page was taken down because it’s obsolete, consider if there’s a newer page on your site that could serve as a relevant link target.

2. Implement 301 Redirects for Moved or Renamed Pages: Whenever you move or delete a page on your site that others (or your own pages) might have linked to, you should set up a 301 redirect from the old URL to the most appropriate new URL.A 301 redirect is a permanent redirection that automatically sends users and search engines from the old address to a new one. This is the proper way to fix broken inbound traffic due to site changes.

   For example, if /old-products/page.html was removed, and there’s a newer page or a category page that covers similar content, redirect /old-products/page.html to /new-products/related-page.html (or even to the parent category or homepage if nothing else fits).

   Redirects ensure that any bookmarks or backlinks to the old URL will still lead somewhere useful, preserving your traffic and “link juice”. Many CMS platforms have easy ways to add redirects (or you can edit your server’s .htaccess or config).

   Note: Use redirects judiciously – always point to a truly relevant page. Don’t just dump users on your homepage, as that can be confusing (and Google prefers relevant redirects). If you genuinely have no replacement content, it’s acceptable to let a 404 stand – but in most cases, you’ll have something similar to direct users to.

3. Reclaim Broken Backlinks (Inbound Links to Your Site): Broken links aren’t only those on your pages – sometimes other sites might be linking to a broken page on your website. This often happens if you removed a page that had external backlinks.From an SEO perspective, this is critical to fix, because you’re otherwise losing the benefit of those backlinks. Using tools like Ahrefs or Google Analytics referrals, identify if any 404 hits on your site are coming from external referrers.

   Once found, you have a couple of options:

   • If possible, reinstate the missing content (e.g., republish a page at that URL or a updated version of it) to immediately recapture the traffic.
   • More commonly, set up a 301 redirect from the broken URL to a relevant page as discussed above. This way, any visits coming from that external link will seamlessly go to a working page on your site. Ahrefs’ Site Explorer has a report for “Broken backlinks” which shows you the strongest broken incoming links – prioritize fixing those.
   • Optionally, you could also reach out to the linking website and politely inform them of the broken link, providing them the new URL to update to. Many webmasters appreciate the heads-up and will update their article. However, this can be hit-or-miss; implementing a redirect on your side guarantees that even if they don’t update the link, the traffic isn’t lost.
4. Fix or Remove Broken Outbound (External) Links: If the broken link is pointing to an external site (an outbound link from your page), you have a few ways to handle it:
   • Update the Link: Check if the content has moved or there’s an official updated link. Perhaps the site changed domain or the article moved to a new URL. A quick Google search might reveal the new location of the resource. Update the href to the correct, working URL (and verify it works).
   • Find an Alternative Resource: If the original resource is gone for good, find another reputable source that provides similar information. For example, if you linked to a statistic on a site that went down, find the same stat from another research source or an archived version (more on that next).
   • Use the Wayback Machine (Archive): In cases where the content is truly unique and you can’t find it elsewhere, you might consider linking to an archived version of the page. The Internet Archive’s Wayback Machine often has snapshots of web pages.If you must preserve the reference, you could find the old page on Wayback and link that (it’s not ideal for user experience, since it’s an archive copy, but it’s better than a dead link). However, use this sparingly – if a resource is important enough to cite, an archive link is a workaround until a better live source is available.
   • Remove the Link (and/or Adjust Text): If the reference isn’t crucial, you might simply remove the hyperlink (and even the mention of that resource) from your content. Ask yourself: does this sentence/paragraph still make sense without the external link? If yes, you can drop the broken link and just present the info generally (or remove the part that relied on that reference).

   No matter which route, make sure you aren’t knowingly sending visitors to a dead page. It’s fine to link to competitor or third-party content if it’s valuable – but if it’s broken, it’s doing no one any good. Either refresh it or cut it.

5. Decide on Out-of-Date Pages with Many Broken Links: Sometimes you’ll find that an entire old page or blog post on your site has multiple broken outbound links (e.g. an old “Top 10 tools” list where half the tools are defunct).In these cases, consider the overall value of the content. Does the page still get traffic or provide value? If so, it’s worth updating the post with new content and new links to replace the rotten ones. This essentially breathes new life into the page – a win for users and SEO.

   If the page is not really valuable anymore (no traffic, outdated topic), you might choose to remove the page entirely (and perhaps redirect it to a newer relevant page on your site). There’s no sense in keeping a low-quality, broken-link-filled page on your site.

   In short, fixing broken links comes down to three options: update it, remove it, or replace it (content-wise). In all cases, ensure that the end user is led to something useful – whether it’s a correct page on your site, a relevant external source, or simply no link at all rather than a misleading one.

6. Improve Your 404 Error Page: Despite your best efforts, some broken links will slip through the cracks or be outside your control (like someone else linking incorrectly to your site).That’s why it’s smart to have a helpful 404 error page as a safety net. Design a custom 404 page that at least acknowledges the error and guides the visitor on what to do next.

   Good practices include: provide a friendly apology (“Oops, that page couldn’t be found”), offer a search bar for your site, link to popular pages or your sitemap, and encourage the user to navigate to other sections.

   This way, even if a user hits a dead link, you have a chance to keep them on your site or help them find what they need. A thoughtful 404 page turns a negative into a neutral (or even a positive) experience.

By systematically fixing broken links and improving the pathways for users, you’ll not only clean up your site for better SEO, but also deliver a smoother experience. After all, a link is a promise – when users click, they expect something. Fulfilling that promise by keeping links in working order builds trust.

Now that your current broken links are (hopefully) fixed, let’s look at how to keep them from coming back with a vengeance.

How to Prevent Broken Links (Keeping Link Rot at Bay)

Websites are not a “set and forget” asset – they require ongoing care. Given how frequently content changes online, completely preventing broken links forever is impossible. However, you can significantly reduce link rot and catch issues early with some smart habits and tools. Here’s how to be proactive:

• Conduct Regular Link Audits: Make broken link checking a routine part of your website maintenance. How often should you check? That depends on how large and frequently updated your site is, but a good rule of thumb is at least once a month.For many blogs or small business sites, a monthly scan will prevent a huge pile-up of issues and only present a handful to fix each time. If your site is very large or you add content daily, you might do checks more frequently (some do weekly). The key is consistency. Regular audits mean no broken link lingers for long.
• Use Automated Monitoring: Take advantage of tools that offer scheduled scans and alerts. As mentioned, services like Dr. Link Check can run automatically on a schedule (daily/weekly) and email you if new broken links are found.The Broken Link Checker plugin for WordPress (cloud mode) also allows scheduling scans and emailing reports to you or your team.

  This way, you don’t have to remember to manually initiate checks – you’ll be notified proactively. Setting this up is like having a watchdog that catches link rot early, often before users notice anything wrong.

• Implement Redirects During Site Changes: Whenever you perform a site overhaul, migration, or even just delete a significant page, plan your redirects in advance. Create a URL mapping from old to new locations so that you don’t inadvertently orphan a bunch of incoming links.If you’re moving to a new domain or restructuring URLs, use tools (or even spreadsheets) to track every changed URL and ensure a 301 redirect is in place. This will preemptively solve what would otherwise become hundreds of broken links overnight. After site changes, run a crawl to double-check nothing was missed.
• Update Your Content & Links Periodically: Content maintenance is key. For evergreen content, schedule a review maybe once a year (or every 6 months for high-traffic cornerstone content) to update any outdated info and update outbound links.Replace old references with current ones if available. This not only fixes broken links but keeps your content fresh. If you have posts that list tools, resources, or statistics, these are prime candidates for periodic link updates since things change fast in many industries.
• Be Cautious with External Linking Practices: You don’t want to avoid linking out – linking to quality external resources is good for user experience and even SEO. But be mindful of what you link to. Prefer linking to authoritative, stable sources that are less likely to disappear.For example, an official organization’s report or a Wikipedia page (which might change but won’t likely vanish) might be safer than a random blog that could be gone next year.

  If you must link to a niche site or temporary resource, that’s fine, but just know to keep an eye on it. In some cases, you might link to an organization’s homepage or a resource section rather than a single PDF that could move.

  Also, when citing time-sensitive data, try to find the primary source (which might have longevity) versus a secondary article that could get deleted.

• Use Archive Links for Reference Material: If you run a research-heavy site (like academic or journalism), consider pre-empting link rot by adding archive links. Some tools (and Wikipedia does this) will include a second hyperlink via the Wayback Machine for cited sources.That way if the source goes offline, the archive link is there as a backup. This might be overkill for most blogs, but for critical citations it’s a strategy to preserve the reference. At minimum, note the publication name or details in text, so if the link breaks, users know what it was.
• Monitor Analytics and 404 Logs: Keep an eye on your Google Analytics (or other analytics) for 404 error hits. Many analytics suites can show a list of 404 page URLs that users hit. If you see certain broken URLs getting traffic, that’s an indicator something is linking to them.Similarly, your server logs or error logs can be monitored for 404 patterns. This is more technical, but it’s how you catch weird issues (like bots or odd links). Some SEO tools and cloudflare-like services also provide broken link reports as part of their offerings.
• Train Your Content Team: If you have multiple people adding content to the site, ensure they know the importance of accurate linking. A bit of training can prevent careless broken links (like pasting a URL with an extra space, or forgetting http://).Encourage use of the CMS’s link picker (if it auto-fills internal links) to avoid typos. It might help to have an editorial checklist that includes “verify all links in the post work correctly” before publishing.

No matter what, accept that link rot will happen – but with the above steps, you’ll catch it early and fix it fast. As one expert quipped, the internet is like a garden that needs regular tending; broken links are the weeds you have to pull occasionally.

Broken Links as an SEO Opportunity (Broken Link Building)

We’ve focused on broken links as a problem to eliminate – but did you know those pesky dead links can also present golden opportunities for SEO? In the world of link building (earning backlinks to your site), there’s a strategy called “broken link building.” This technique turns the existence of broken links on other websites to your advantage.

Here’s how it works in a nutshell: You find a broken link on another site (preferably one in your industry or niche) that used to point to a piece of content similar to something you have on your site.

Then you reach out to the webmaster of that site and suggest they replace their broken link with a link to your relevant content. The site owner wins by fixing a dead link on their page (improving user experience), and you win by gaining a new backlink to your site.

Why does this strategy make sense? Consider that over 42% of websites have broken links on them – that’s a lot of broken links out there. Many of those broken links were originally pointing to pages that had useful content (before they went dead).

If you can provide an equally useful replacement, you’re helping the other site’s owner as well as yourself. It’s essentially a “win-win”: they get to eliminate a bad link, and you get a quality backlink.

A common playground for broken link building is Wikipedia. Wikipedia articles often have dead links in their reference sections (marked with a “[dead link]” label). Some SEO folks will create content on their own sites to replace a dead reference and then suggest it to Wikipedia editors.

However, Wikipedia links are nofollow (they don’t pass PageRank), so the direct SEO value is limited – though it can still bring some traffic or credibility. A more fruitful approach is finding broken links on blogs, resource pages, or articles in your niche.

For example, imagine you run a tech blog and discover that a high-authority site has a 2018 article about “best coding practices” which cites an external resource that is now a broken link.

If you happen to have a great article on modern coding practices, you could contact the site’s editor: highlight that their article XYZ has a dead link, and politely propose your article as an updated replacement. Many website owners appreciate the courtesy (you’re helping them improve their site) and will swap in your link if your content is truly relevant and high-quality.

To do broken link building at scale, SEO tools can help:

• Use Ahrefs or SEMrush to find broken outbound links on other websites. For instance, Ahrefs has a “Broken Links” report for any domain – you could plug in a competitor’s site or a known resource hub in your field and see what external links from their site are 404.
• Search for keywords plus phrases like “404 not found” or use Google’s search operators. There are also specialized tools or Chrome extensions that can scrape a page and find broken links on it quickly (useful for scanning a “Links” or “Resources” page in your industry).
• When you find a broken link, check its original content (via Archive .org’s Wayback Machine) to understand what was there. That helps you identify if you have (or can create) content that fills the same need. You might even make a new improved piece of content specifically targeting that opportunity.
• Then reach out with a friendly email. The success rate can vary (some site owners might ignore unsolicited emails), but even a 10-20% success rate can yield valuable links if you do this systematically.

Broken link building is a creative, resource-intensive tactic, but it’s one more way to extract some benefit from the web’s link rot. It’s especially effective for getting links from resource lists or older articles that still have authority but haven’t been updated in a while. By helping others fix their broken links, you earn goodwill and backlinks – not a bad trade-off!

(Remember: Always ensure your content genuinely fits as a replacement. The goal is to add value to users, not just trick webmasters into linking to you. Quality and relevance are paramount for this strategy to work in the long run.)

Conclusion: Keep Your Site Healthy and User-Friendly

Broken links may be inevitable on the ever-changing web, but they are not something you can afford to ignore. As we’ve seen, a few dead links can snowball into lost visitors, diminished trust, and leaking SEO value.

The flip side is also true: a site with well-maintained, up-to-date links demonstrates professionalism and provides a smooth user experience, which search engines and users both reward.

The takeaway? Make broken link checks and fixes a regular part of your website routine. It’s like dental hygiene for your website – a little flossing (scanning) and cleaning now and then prevents serious decay down the line.

Use the tools and techniques we discussed: set up automated scans, monitor those 404s, and act quickly when an issue is spotted. When you publish new content, double-check your links.

When you overhaul old content, refresh those references. This ongoing vigilance will keep your site’s user experience and SEO performance in top shape.

Finally, don’t be afraid to turn this chore into an opportunity. By keeping your own backyard clean and even helping others fix their broken links (and earning backlinks in return), you’ll strengthen your site’s authority. Every fixed link is one less pothole on the information superhighway, making the web better for everyone.

Now, armed with this knowledge and a toolkit of resources, it’s time to put it into action. Take a few minutes today to run a broken link check on your website – you might be surprised at what you find.

Then get those links fixed up. Your visitors will thank you, and so will your future self when your site is ranking higher and delighting users rather than frustrating them.
