Are 404s Bad for SEO?

Many site owners have encountered the dreaded “404 Not Found” error, either from a broken link, a deleted page, or a mistyped URL. When you spot these in your analytics or Google Search Console, the natural question is: Are 404s bad for SEO?

The short answer is no, not always. A few 404 errors are a normal part of maintaining any healthy website. But unmanaged 404s, especially those from important or linked pages, can harm user experience, waste link equity, and create crawl inefficiencies.

In this updated guide, you’ll learn what 404s really mean, how they affect SEO, how to find and fix them using Google Search Console, and how to decide between letting a page return a 404 or setting up a 301 redirect.

What Are 404 Errors?

A “404 Not Found” status code means the server cannot locate the requested page. It’s the web’s way of saying, “The content you’re looking for doesn’t exist here.”

When you enter a URL, the server responds with a status code:

• 200 OK: The page exists and loads successfully.
• 404 Not Found: The page doesn’t exist.
• 301 Moved Permanently: The page has been redirected to a new URL.

A 404 error page can be a default server message or a custom-designed page that matches your site’s branding. Most content management systems (like WordPress or Shopify) automatically generate 404s for missing content.

Why Do 404 Errors Occur?

Common reasons include:

• Deleted or moved pages: Pages removed without a redirect, often during redesigns or product retirements.
• Typos in links or URLs: A simple misspelling in a link or manual entry can trigger a 404.
• Broken external links: Other websites linking to outdated URLs on your site.
• Changes in URL structure: Modifying slugs, categories, or permalink formats without redirects.
• Server or configuration errors: Misconfigured rules or firewall restrictions can sometimes block access unintentionally.

Are 404 Errors Bad for SEO?

404s are not an automatic ranking penalty. Google’s John Mueller has repeatedly confirmed that having some 404s is normal and expected. However, problems arise when they affect important pages or user experience.

Here’s how unmanaged 404s can cause indirect SEO issues:

User Experience

When visitors land on broken pages, they often leave immediately. High bounce rates and short dwell time can signal poor satisfaction, which may hurt engagement metrics over time.

Loss of Link Authority

If external sites link to pages that return a 404, the link equity from those backlinks is lost. Redirecting those URLs to relevant pages helps preserve your site’s authority.

Brand Perception

Frequent 404s can make your site appear neglected or unreliable. A well-maintained, consistent browsing experience builds trust and encourages visitors to return.

Crawl Efficiency

Excessive 404s can slow search engine crawlers. While Googlebot handles them gracefully, constant dead ends waste crawl resources that could be spent on new or updated content.

Bottom line: A few 404s are fine. But large volumes of broken or linked pages should be addressed quickly for both technical and user experience reasons.

How to Find and Fix 404s in Google Search Console (GSC)

Google Search Console is your most valuable tool for identifying and managing 404 errors. Here’s how to use it effectively:

Step 1: Check for 404s in the “Page Indexing” Report

• Open Search Console → Pages → Not Indexed tab.
• Look for items labeled “Not Found (404)”.
• These URLs are pages Google tried to crawl but couldn’t find.

Step 2: Inspect Individual URLs

• Click on any 404 URL and choose “Inspect URL.”
• GSC will show whether the URL is returning a genuine 404, redirecting, or blocked.
• You can also Run a Live Test to confirm if the issue still exists.

Step 3: Check Where the URL Is Linked

• Review the “Referring Page” (if available) or use a crawler tool (like Screaming Frog or Ahrefs) to find internal links pointing to the missing page.
• Update or remove those links as needed.

Step 4: Decide on Action (404 vs 301)

Once you’ve identified the missing page, decide whether to redirect or leave it as a 404 (see next section).

Step 5: Validate Fixes

After updating or redirecting URLs, return to GSC and click “Validate Fix.” Google will re-crawl and confirm the issue is resolved.

💡 Tip: Set a recurring reminder (monthly or quarterly) to review your “Not Found” URLs in GSC. Sites that update content frequently should monitor even more often.

404 vs. 301 Redirect: How to Decide

Choosing whether to redirect or keep a 404 depends on user intent and content relevance.

Use a 404 When:

• The content no longer exists and has no replacement.
• The page was temporary (e.g., a seasonal promotion or event).
• The topic is outdated or irrelevant.

Returning a real 404 tells both users and search engines that the content is gone — preventing confusion or mismatched results.

Use a 301 Redirect When:

• The content has moved to a new location.
• You’ve merged or updated similar content.
• The old page has backlinks or search visibility worth preserving.

Redirects help retain ranking signals and ensure visitors land on a relevant alternative.

Quick Decision Framework

Designing an Effective 404 Page

A well-designed 404 page turns a dead end into a helpful experience.

Essential Elements:

• Clear message: “Page not found” in plain language.
• Navigation links: Return to homepage or main sections.
• Search bar: Help users find what they were originally looking for.
• Brand consistency: Match your site’s visual design and tone.
• Optional: Display related or popular pages, or a light-touch touch of humor (if on brand).

Example message:

“We couldn’t find the page you’re looking for. Try searching our site or head back to the homepage.”

Avoid turning your 404 into a marketing pitch — focus on usefulness.

Examples of 404 Pages from Top Brands

Many large brands pay special attention to their 404 pages, turning what could be a dull or frustrating user experience into something more helpful, or even entertaining. Below are some notable examples and what we can learn from them.

GitHub

Overview: GitHub’s 404 page features a fun graphic referencing the “Octocat,” their mascot, with a visually appealing design.

Key Takeaway: Even a major developer hub keeps things simple. They offer a clear message, a few navigation links, and brand-based artwork that reassures users they’re still on GitHub.

Airbnb

Overview: Airbnb’s 404 page is minimalist with a straightforward apology note and a link to the homepage or to browse popular destinations.

Key Takeaway: They put user experience first by promptly guiding visitors to the main functional areas of the site (like searching for places to stay).

Pixar

Overview: Pixar’s 404 page often showcases one of their beloved characters in a creative scene related to something being “lost.”

Key Takeaway: This approach not only fits Pixar’s brand identity but also adds a bit of playful charm, turning a potential frustration into a smile.

What We Can Learn:

• Each of these brands keep navigation straightforward.
• Each 404 page has consistent visual and textual tone with the rest of the site.
• They avoid too much clutter, focusing instead on the message and key site links.
• Some opt for creative or humorous designs to turn an error into a memorable brand moment.

Ensuring There Is a Proper 404 Page (Not a Soft 404)

A soft 404 occurs when a missing page looks like a 404 to users but returns a “200 OK” status code to search engines.

Why this matters:
Search engines may mistakenly index these pages, wasting crawl budget and creating duplicate or low-quality results.

To fix soft 404s:

• Make sure missing pages return a genuine 404 or 410 status code.
• If a real page exists elsewhere, set a 301 redirect.
• Use GSC’s “Page Indexing” → “Soft 404” report to identify and correct them.

Practical 404 Management Tips

• Use Google Search Console regularly to monitor “Not Found” pages.
• Audit internal links after content updates or site migrations.
• Track inbound broken links with tools like Ahrefs or Semrush and decide if a redirect makes sense.
• Fix typos in URLs and update navigation menus promptly.
• Avoid blanket redirects (e.g., all 404s to the homepage), as Google sees that as confusing.
• Check server logs to see which URLs users or bots hit most frequently.
• Document redirects to avoid loops or chains during future updates.

Conclusion

404s are not the enemy of SEO – neglect is. A few missing pages are inevitable, but a pattern of ignored 404s can erode link authority, frustrate users, and signal poor site maintenance.

Use Google Search Console as your command centre: identify missing pages, trace links, and apply the right fix. Redirect valuable URLs when relevant, and allow true 404s for content that’s gone for good.

By auditing regularly, creating helpful 404 pages, and maintaining accurate redirects, you protect both your user experience and your site’s long-term SEO performance.

In short: 404s don’t hurt SEO – unmanaged 404s do.
