A 404 error means a page doesn’t exist anymore. Fix the ones that have backlinks, internal links, or traffic by redirecting or restoring the page; leave true “never existed” URLs alone and focus on a helpful custom 404 page.
Most sites have a few 404s. The trick is knowing which ones to fix, how to fix them without creating redirect chains, and how to turn the unavoidable 404s into a decent user experience instead of a dead end.
What is a 404 error (and why it matters for UX and SEO)?
A 404 Not Found is an HTTP status code the server returns when it can’t find the requested URL. Common triggers:
-
A page was deleted or moved without a redirect
-
A link has a typo or points to the wrong slug
-
An external site links to a page you no longer host
-
URL structure changed during a redesign or migration
For users, a 404 is a dead end. For SEO, the impact depends on context. A handful of soft 404s on random URLs won’t tank rankings. But if high-traffic pages, product pages, or pages with backlinks start returning 404, you lose link equity and frustrate visitors who expected content.

Which 404 errors actually hurt SEO (and which don’t)?
Here’s what most guides skip: not all 404s deserve your time.
404s worth fixing
Prioritize 404s that meet any of these conditions:
-
The URL has backlinks (especially from relevant sites)
-
The URL gets organic traffic or conversions
-
The URL is linked from your own navigation, sitemap, or high-traffic pages
-
The content still exists under a slightly different URL
Example: Your old blog post /best-budget-laptops-2023 still ranks and has 12 referring domains. After a redesign, it now returns 404. That’s a clear fix: restore the content or 301 redirect to the closest equivalent page.
404s you can safely ignore
Google’s own guidance says you can ignore 404s for URLs that shouldn’t exist: test URLs, parameter spam, old tag pages, or URLs created by hackers trying to probe your site.
If a URL:
-
Has no backlinks
-
Has no traffic
-
Has no internal links pointing to it
-
Was never a real page
…it’s fine to let it 404. Forcing a redirect to your homepage for every random 404 creates a “soft 404” problem and confuses search engines.

How to find 404 errors on your site
You need a reliable way to surface 404s before users do.
Use Google Search Console
In Search Console, go to Pages > Not found (404). You’ll see:
-
URLs Google tried to crawl that returned 404
-
Why Google found them (internal links, external links, sitemap, etc.)
Export the list and sort by:
-
Number of referring domains
-
Impressions/clicks (if available)
-
Internal linking count
That gives you a shortlist of high-value 404s to fix first.
Crawl your site with a tool
Tools like Screaming Frog, Sitebulb, or Ahrefs Site Audit can crawl your site and flag:
-
Broken internal links (links on your site that lead to 404s)
-
External links pointing to missing pages
-
Redirect chains ending in 404
Run a full crawl, filter for “404” status codes, and export. Cross-check with Search Console to prioritize.

Check server logs (advanced)
If you have access to server logs, look for repeated 404 responses for specific URLs. This catches 404s that bots and users hit but haven’t made it into Search Console yet. Useful for large sites with thousands of pages.
404 error fixes that protect user experience and SEO
Now for the actual fixes. These are the moves that preserve rankings and keep users from bouncing.
1. Restore the missing page (when it makes sense)
If the page used to perform well and you deleted it by accident, the cleanest fix is often to bring it back.
Do this when:
-
The URL has strong rankings or traffic
-
The content is still relevant
-
You don’t have a clear replacement page
Example: An e‑commerce site deleted a category page /mens-running-shoes during a cleanup. It was driving 1,200 organic visits/month. Restoring the page with updated content recovered most of that traffic within a few weeks.
When restoring, keep the same URL. If you must change the slug, set up a 301 redirect from the old URL to the new one.
2. 301 redirect to the closest relevant page
If the content no longer exists but there’s a clear substitute, use a 301 (permanent) redirect.
Good targets for redirects:
-
A newer version of the same content
-
A parent category or hub page
-
A closely related article or product
Example: A SaaS company retired /features/time-tracking and merged that functionality into /features/productivity. Instead of 404, they 301‑redirected the old URL to /features/productivity and updated internal links. Organic traffic to that URL stabilized within a month.
Avoid:
-
Redirecting everything to the homepage
-
Redirecting unrelated pages just to “save” link equity
-
Creating long redirect chains (A → B → C → D)
Each extra hop slows pages down and can dilute link value.

3. Update or remove broken internal links
Sometimes the page is gone on purpose, but your own site still links to it.
Fix by:
-
Updating the link to the new URL
-
Removing the link if the content is no longer relevant
-
Replacing it with a better, more current resource
Example: A help center had 27 articles linking to /setup/old-dashboard. That page was replaced by /setup/new-dashboard. Updating those 27 internal links removed the 404s and improved crawl efficiency.
4. Handle external broken links
You can’t control other sites, but you can influence what happens when their links hit your 404s.
Options:
-
Set up targeted 301s for known high-value external links
-
Reach out to important partners and ask them to update the link
-
Use a custom 404 page that helps users find the right content
If a major industry blog links to /guide/seo-basics and that URL now 404s, a 301 to an updated guide preserves both traffic and the relationship.
5. Fix CMS, permalink, and server issues
Not all 404s come from deleted pages. Some are configuration problems.
Common culprits:
-
Changed permalink structure in WordPress without redirects
-
Corrupted
.htaccessfile on Apache servers -
Plugin or theme conflicts that break URL rewriting
-
Incorrect server rules after a migration
If suddenly many valid pages start 404ing after a change, roll back the recent change and test in a staging environment first.

How to design a helpful custom 404 page
Some 404s are inevitable. You can’t redirect every typo or spam URL. That’s where a well-designed custom 404 page matters.
A good 404 page should:
-
Clearly state that the page wasn’t found
-
Offer obvious next steps (search, popular pages, category links)
-
Match your site’s design so users know they’re still on your site
-
Avoid blaming the user
Example elements to include:
-
Short headline: “Page not found” or “We couldn’t find that page”
-
Brief explanation: “The link might be broken or the page may have moved.”
-
Search box
-
Links to:
-
Homepage
-
Main categories or top products
-
Popular blog posts or resources
-
-
Optional: a light touch of personality (a small illustration or witty line), as long as it doesn’t obscure the options
Bad example: a bare server message like “404 Not Found – The requested URL was not found on this server” with no navigation. That sends users straight to the back button.
Preventing 404 errors before they happen
You’ll always have some 404s, but you can reduce them dramatically with a few habits.
Plan URL changes carefully
Before renaming slugs or restructuring URLs:
-
Audit existing URLs for traffic and backlinks
-
Map old URLs to new ones in a spreadsheet
-
Implement 301 redirects before going live
-
Test key URLs after launch
Use a link checker regularly
Run a broken link scan monthly:
-
In WordPress, plugins like Broken Link Checker can help
-
Standalone tools can crawl and report broken internal/external links
Fixing a batch of broken links every month is easier than cleaning up hundreds of 404s after a redesign.

Monitor Search Console and analytics
Set a routine:
-
Check Search Console’s 404 report every 2–4 weeks
-
Watch for sudden spikes in 404s after deployments
-
Track organic traffic and conversions on key pages
If a core landing page suddenly drops to zero traffic and starts returning 404, you want to know fast.
Be careful with user-generated URLs
Sites with forums, profiles, or tags often generate thousands of low-value URLs that later 404.
Use:
-
noindexfor thin or auto-generated pages -
Canonical tags where appropriate
-
Careful rules for when to create new tag or category pages
This keeps your index clean and reduces pointless 404 noise.

FAQ
Do 404 errors hurt my site’s SEO?
Not automatically. Isolated 404s on URLs that shouldn’t exist don’t penalize your whole site. SEO problems arise when important pages with traffic, backlinks, or internal links start returning 404. Fix those, and you can safely ignore the rest.
Should I redirect all 404s to the homepage?
No. Redirecting every 404 to the homepage creates “soft 404s” and confuses search engines. Only 301 redirect when there’s a clear, relevant replacement page. For random or spam URLs, a proper 404 response is better.
What’s the difference between a 404 and a soft 404?
A standard 404 returns a 404 status code and tells search engines the page doesn’t exist. A soft 404 happens when a page returns a 200 OK status but shows a “page not found” message. Search engines may treat soft 404s as low-quality pages and stop indexing them.
How quickly should I fix a 404 on a high-traffic page?
As soon as you notice it. If a page that drives significant traffic or conversions starts 404ing, every hour counts. Restore the page or implement a 301 redirect immediately, then investigate why it happened.
Can a custom 404 page improve user experience?
Yes. A thoughtful 404 page keeps users on your site by offering search, navigation, and clear next steps. It won’t fix the missing page, but it reduces bounce rates and frustration compared to a generic server error.
Conclusion
Don’t chase every 404. Focus on fixing 404s that affect real users and real rankings: pages with traffic, backlinks, or internal links. For the rest, serve a clean 404 status and invest in a custom 404 page that guides people to useful content instead of a dead end.
