Broken Internal Links vs Broken External Links What's the Difference?

One of the biggest mistakes I made when I first started maintaining larger WordPress websites was treating every broken link exactly the same.

A broken link was a broken link.

Or so I thought.

After managing websites with hundreds and eventually thousands of articles, I realized there are actually two completely different problems hiding behind that phrase.

Broken internal links.

Broken external links.

While both create a poor experience for readers, they happen for completely different reasons and usually require different solutions.

Understanding that difference completely changed the way I maintain my websites.

Instead of blindly replacing URLs, I now know where to look, what questions to ask, and how to prevent many of these problems from happening again.

If you're still deciding which tools you should use, I'd recommend starting with my comparison of the best broken link checker plugins for WordPress. I compare the workflows I personally use and explain why I eventually built my own solution after becoming frustrated with constantly jumping between reports and articles.

You'll also find my guide on how to find broken links in WordPress without wasting hours helpful if you're ready to start cleaning up your own website. That's the exact workflow I follow across my larger content sites.

Since broken links almost always lead me into improving my internal SEO, I also recommend reading my guide covering the best internal linking plugins for WordPress. Those two maintenance tasks naturally go together on nearly every website I manage.

What Is a Broken Internal Link?

A broken internal link points to another page on your own website that no longer works.

Maybe you deleted an article.

Maybe you changed a permalink.

Maybe you reorganized your categories.

Maybe you migrated your website and accidentally left old URLs behind.

Whatever the reason, the destination exists on your own website, which means you control both sides of the problem.

In my experience, that's actually good news.

Since you own the content, broken internal links are usually much easier to fix than broken external links.

What Is a Broken External Link?

Broken external links are completely different.

These point to someone else's website.

That's also what makes them so unpredictable.

You have absolutely no control over what happens after you publish the article.

The website you linked to might shut down.

The company could change domains.

The page may get deleted.

The content could move to an entirely different URL.

Sometimes a business simply disappears overnight.

I've had all of those happen over the years.

That's why external links require ongoing maintenance even if your own website never changes.

Which Type Causes More Problems?

If I had answered this question years ago, I probably would've said broken internal links.

Today I'd actually say broken external links.

Not because they're necessarily worse for SEO, but because they're constantly changing without your knowledge.

I can control my own website.

I can't control thousands of other websites that I've referenced over the years.

That's exactly why older content slowly accumulates broken external links if it isn't maintained regularly.

Research and industry experience consistently show that websites evolve over time, pages move, and resources disappear, making link maintenance an ongoing responsibility rather than a one-time task. :contentReference[oaicite:0]{index=0}

How I Handle Broken Internal Links

Whenever I find a broken internal link, I ask myself one simple question.

Should this page still exist?

If the answer is yes, I usually restore the destination or update the URL.

If the answer is no, I look for another article that serves the same purpose.

If one exists, I update the internal link.

If not, I usually rewrite the surrounding paragraph so it still reads naturally.

I never want readers wondering why I recommended something that no longer exists.

That extra attention to detail has helped keep my older content much more useful over time.

How I Handle Broken External Links

Broken external links usually require a little more detective work.

I don't automatically replace them with the first similar website I find.

I ask myself several questions.

• Does this resource still exist somewhere else?
• Has the company simply changed URLs?
• Is there now a better resource available?
• Does the paragraph still need an external link at all?
• Would one of my own articles now answer this question better?

Sometimes the best solution isn't another external link.

Sometimes it's replacing that reference with one of my own updated guides.

That's another reason internal linking naturally improves while I'm fixing broken links.

Can Broken Internal Links Hurt SEO More Than Broken External Links?

People ask me this fairly often, and I don't think there's a simple winner.

They create different problems.

Broken internal links make it harder for readers and search engines to move around your own website.

Broken external links usually make your content feel outdated because the resources you're recommending no longer exist.

If I had to choose which one deserves my attention first, I'd usually start with broken internal links on pages that already receive a lot of traffic.

Those are completely under my control, and fixing them often improves the overall experience immediately.

Once those are in good shape, I move on to external resources that need updating.

How Broken Internal Links Usually Happen

I've accidentally created broken internal links more times than I'd like to admit.

Fortunately, I also know exactly why they happen now.

• Changing permalink structures.
• Deleting old articles.
• Merging two similar posts together.
• Moving content into different categories.
• Website redesigns.
• Importing or migrating WordPress websites.
• Removing old landing pages.

Almost every large website eventually experiences at least one of these.

The important thing isn't avoiding every mistake.

It's having a process that helps you find and fix them before readers begin running into dead ends.

How Broken External Links Usually Happen

External links are a completely different story because they're constantly changing without your involvement.

Over the years I've seen every scenario imaginable.

• Companies changing domains.
• Products being discontinued.
• Blog posts getting deleted.
• Entire websites shutting down.
• Resources moving behind paywalls.
• Businesses going out of operation.
• Manufacturers replacing product pages.

None of those are your fault.

Unfortunately, they're still your responsibility if you're recommending those resources inside your own articles.

That's why I think maintaining external links is something every serious website owner should plan for instead of treating it like an occasional emergency.

What I Do Before Removing Any Broken Link

I almost never delete a broken link immediately.

Instead, I ask myself a few questions first.

Can I update it?

Should I replace it?

Does another page provide even better information today?

Would one of my own articles now serve readers better?

Only after answering those questions do I decide whether the link should stay, change, or disappear altogether.

I've found that approach produces much stronger articles than simply deleting every dead URL I encounter.

How Internal Linking Often Solves External Linking Problems

This is probably one of my favorite maintenance tricks.

Let's say an article I recommended five years ago no longer exists.

Instead of immediately searching for another outside website, I first ask whether I've written something that now answers the same question.

Quite often, the answer is yes.

That's another opportunity to strengthen my own internal linking while replacing an outdated external resource.

It's one of the reasons my internal link structure has become much stronger over time.

Rather than constantly sending readers away from my website, I'm often able to direct them toward newer, more detailed guides I've already published.

If you're trying to build that same habit, I'd strongly recommend reading my guide on the best internal linking plugins for WordPress. Internal linking has become one of the biggest parts of my long-term content maintenance strategy.

The Workflow I Follow Every Month

I don't have a complicated maintenance schedule.

I simply stay consistent.

Every month I set aside time specifically for improving existing content.

That usually includes:

• Scanning for broken links.
• Reviewing older articles.
• Adding links to newer content.
• Replacing outdated recommendations.
• Updating affiliate products.
• Improving article formatting.
• Refreshing screenshots where needed.

Those small improvements have had a much bigger impact on my websites than constantly chasing brand-new content ideas.

If you're still developing your own maintenance process, I'd also recommend reading my article explaining how I find broken links in WordPress without wasting hours. That's the exact workflow I personally follow before making any updates.

Why I Eventually Built My Own Broken Link Plugin

After years of maintaining growing WordPress websites, I realized something.

The difficult part wasn't identifying broken links.

The difficult part was cleaning up the surrounding content efficiently.

I wanted to see the paragraph immediately.

I wanted to decide whether the sentence should stay.

I wanted to remove only the hyperlink if appropriate.

I wanted to replace the destination across multiple articles when necessary.

I wanted everything reviewed before any changes were made.

That exact workflow became Broken Link Cleanup Pro for WordPress.

It wasn't designed to create another report.

It was designed to help me maintain content much faster while keeping every editorial decision in my hands.

My Recommendation

If you're only checking whether links work, you're thinking too small.

Every broken internal link and every broken external link is an opportunity to improve your website.

Use those moments to strengthen your content.

Add newer internal links.

Replace outdated recommendations.

Improve readability.

Refresh examples.

Leave every article better than it was before you opened it.

That's been my philosophy for years now, and it's one of the biggest reasons my older content continues performing long after it's been published.

If you're looking for more tools built around that same maintenance philosophy, take a look through our complete WordPress Plugins collection. Every plugin there was created to solve a real problem I encountered while managing larger WordPress websites.

Frequently Asked Questions

Which is worse, a broken internal link or a broken external link?

Neither is good, but they affect your website differently. Internal links impact navigation within your own website, while external links often make articles feel outdated because recommended resources no longer exist.

Should I replace broken external links with internal links?

If you have a high-quality article that answers the same question, absolutely. I do this frequently while updating older content because it improves both the reader experience and my internal linking.

How do I prevent broken internal links?

Regular website maintenance helps tremendously. Whenever you change URLs, delete articles, or reorganize your website, it's a good idea to scan for broken internal links afterward.

How often should I check for broken internal and external links?

For growing websites, I recommend making it part of your ongoing maintenance routine instead of waiting until problems become overwhelming. Small, regular updates are much easier than major cleanup projects.
