404 Page Checker

Enter a URL to scan all its outgoing and internal links. We will test each one and display whether it connects successfully (green) or returns a 404 error (red).

Find and fix broken links on a page

A 404 status code fundamentally means the page you are looking for has vanished or never existed. Finding and resolving these dead-ends is critical for preserving your domain equity and ensuring a frictionless experience for your visitors.

What is the 404 Page Checker?

The 404 Page Checker is a free, fast diagnostic utility built to help webmasters, digital marketers, and SEO specialists identify broken internal and external exit points hidden across their domains.

By inputting any specific URL, our engine instantly strips the document, collecting every resolvable hyperlink mapped to its anchor text. It then systematically knocks on each door. If it receives a successful HTTP response, it marks it green. If it hits a notorious `404 Not Found` response, it lights up red instantly.

Rather than waiting for your users to complain about a dead link or letting Google demote your content due to poor maintenance, you stay proactive, preserving link flow accurately.

Primary Benefits

  • Preserve Crawl Budget: Don't force Googlebot to waste its time crawling non-existent pages.
  • Stop Authority Bleed: Keep "link juice" flowing effectively across your internal site architecture.
  • Improve User Experience: Eliminate frustrating dead ends ensuring users follow their intent correctly.
  • Instant Visual Audit: Instantly map anchor tags directly to broken endpoints visually in real-time.

Why do 404 Links Happen?

Links decay over time. Without regular audits, your digital real estate slowly fills with cracks. Here are the most common reasons your page might be bleeding 404 errors.

Deleted Content

You or another site owner deleted a post or product page but failed to set up a 301 Redirect to pass traffic seamlessly to a new location.

URL Restructuring

During a site migration or clean-up, slugs were changed (e.g., from /about-us to /about) but hardcoded internal links were ignored.

External Attrition

You link out to a valid, valuable resource off-domain, but over the years, that target domain expired or deleted its directories permanently.

Using the Checker to Fix Your Site

1

Run the Audit

Enter your target URL (like a popular blog post or your homepage). The checker safely and concurrently verifies every hyperlink.

2

Locate Red Alerts

Scan the returned table for red "404" status badges. We expose the exact anchor text allowing you to pinpoint where the link lives.

3

Redirect or Replace

Change the broken link in your CMS to point to a working page, remove it completely, or enact a 301 Redirect on your server if applicable.

The Hard Truth About 404s and the Algorithm

Search engines inherently demand reliability. When Googlebot continuously steps onto your pages and finds bridges leading nowhere (404 errors), it registers structural instability. While a single broken link won't devastate your rankings, a neglected site brimming with dead-ends absolutely suffers.

As the proportion of broken links rises, search engines view the website as outdated or abandoned. Crawl frequency shrinks drastically, preventing new content from being indexed efficiently, all while eroding the precious topical authority you've built.

Lower Bounce Rates

Users stay on healthy paths.

Higher Crawl Rates

Bots map active URLs instantly.

Faster Indexing

Fresh content is discovered quicker.

Stronger SEO

Avoid algorithmic friction completely.

Comprehensive Page Link Auditing Features

Unlike standard broken link checkers that only alert you to errors, our 404 Page Checker provides a full visual map of every link on your page. See exactly which links are working and which ones are failing.

Valid Link Confirmation

See a definitive list of all healthy, working links on your page. Valid links are highlighted in green alongside their exact anchor text, giving you complete confidence in your active link profile.

Immediate 404 Detection

Broken links are instantly flagged in red. We pull the exact anchor text or image associated with the dead link so you can locate and fix it without hunting through source code.

Anchor Text Mapping

Every scanned URL is paired directly with its click text or image path. This full mapping helps you quickly understand the user context behind every internal and external link.

Real-time Validation

Our engine fetches links live as you wait. You aren't relying on outdated cached data; you're seeing the exact status of your page's connections in that specific moment.

Internal & External Reach

We don't discriminate between links pointing inside your domain or to third-party sites. The scanner resolves paths universally, ensuring your outgoing citations are as reliable as your internal menus.

Actionable Output

By presenting both the good and the bad in a clear, sortable table, you can easily copy the results to your developers or content team to execute immediate fixes.

A Complete View of Your Links

Valid Links (Green)

We display all successfully resolved links in green. This confirms that your crucial navigation paths, call-to-action buttons, and external references are functioning perfectly and delivering a 200 OK status.

404

Broken Links (Red)

Links pointing to dead pages, typos, or expired domains are highlighted in red. These 404 errors require immediate attention as they disrupt user experience and waste crawl budget.

Frequently Asked Questions

Why show valid links instead of just broken ones?

Seeing only broken links leaves you in the dark about the rest of your page architecture. By displaying the correct, valid links in green alongside the broken ones, you get a full, transparent audit of exactly what our tool scanned. It provides peace of mind that your critical links were actually tested.

What exactly is a 404 error?

A 404 error is an HTTP status code indicating that the server could not find the requested webpage. This usually happens when a page has been deleted, a URL slug was changed without a redirect, or the link was simply typed incorrectly.

Does this tool check images?

Yes, if an image is wrapped in an anchor tag or acts as a linking element, our tool will extract the image path as the anchor context, making it easy to identify which visual element is leading to a 404 page.

Do broken links really hurt SEO?

Yes. Search engines view broken links as a sign of an outdated or poorly maintained website. While one or two might not tank your rankings, an accumulation of 404 errors wastes crawl budget, frustrates users, and ultimately reduces your search visibility.

Can I copy the results table?

Absolutely. The results table pairs the target URL directly with its anchor text. You can easily highlight and copy this data to share with developers or content managers to execute fixes across your CMS.

How do I fix a red 404 link?

You have three main options: 1) Edit the link on your page to point to the correct URL, 2) Remove the link entirely if the destination resource is permanently gone, or 3) Set up a 301 redirect on your server if the destination page was simply moved.
