A not found 404 error means Googlebot attempted to crawl a URL on your site and the server responded that the page does not exist. In most cases, the 404 itself is not the problem. The real issue is whether the missing URL was supposed to exist in the first place.
That distinction matters because most websites waste time fixing the wrong 404s. Some missing URLs deserve a redirect. While some should be restored and others should return a 410 status. And many should simply be ignored entirely.
This guide walks through how to identify which 404 page not found errors matter, how to fix them correctly, how to prevent soft 404 issues, and how to clean up your Search Console reports without creating larger indexing problems.
I have seen this happen repeatedly on large sites: teams open Search Console, see thousands of 404s, and immediately start redirecting everything. That usually creates more problems than it solves.
What “Not Found (404) Error” Means in Search Console
When Googlebot requests a URL and your server responds with a 404 HTTP status code, Google logs the page under:
Google Search Console → Indexing → Pages → Not Found (404)
This does not automatically mean something is wrong with your site. A 404 is a completely valid server response for content that no longer exists.
The important question is not: “Why does this page return 404?”
The important question is: “Should this page exist?”
If the answer is no, the 404 is often correct and does not need fixing.
How to Find What Is Creating the 404?
Before fixing a 404 error, first identify what is actually generating the URL. It can be a dead URL coming from your sitemap that requires a completely different fix than one created by a spam backlink or broken JavaScript.
Start with the URL Inspection tool in Google Search Console. In many cases, Google will show whether the URL was discovered through your sitemap, internal links, or external sources. If the dead URL exists in your sitemap, remove it and resubmit the sitemap.
Broken internal links are another very common cause of persistent 404 errors, especially after migrations, permalink changes, or theme rebuilds. This is also why running a broader GSC indexing audit framework helps uncover larger crawl and indexing issues.
If the 404s are coming from external spam URLs or fake bot-generated endpoints, they are usually safe to ignore.
Step 1: Pull the Not Found List
The first step is to open Google Search Console and navigate to:
Indexing → Pages → Not Found (404)
Export the full URL list before making any changes.
If your site also suffers from indexing inconsistencies, crawl instability, or pages that Google discovered but never indexed, it helps to pair this process with a broader crawled, currently not indexed guide so you can separate crawl issues from actual missing-page issues.
Once exported, begin categorizing URLs by pattern:
- Old blog URLs
- Deleted products
- Parameter URLs
- Broken media paths
- Spam-generated URLs
- Migration leftovers
- Typos in internal links
Pattern recognition matters because one template-level mistake can generate thousands of 404s.
Step 2: Sort 404s by Demand, Not by Page Type
Most site owners I have worked with sort 404s emotionally. On larger sites, I start by ignoring the URL type completely and sorting the export by demand signals first.
The ugly-looking URLs are not always the dangerous ones. The valuable ones are the URLs that still have links, impressions, or user journeys attached to them.
Google does not care about the page type. Google cares whether the URL still has demand signals attached to it. That means the URLs worth fixing first are the ones with:
- Backlinks
- Historical impressions
- Traffic
- Internal link references
- Migration history
Google’s own documentation supports prioritizing pages based on actual value and demand rather than arbitrary classifications.
Action 1: Restore the Missing Page
It’s very important to restore the page if:
- The content was deleted accidentally and it is either a money page or an important pillar page
- The page still receives traffic
- The page still ranks for queries
- The URL has valuable backlinks
- The removal created broken internal journeys
This commonly happens after migrations or theme rebuilds. If the original content still serves a purpose, restoring the page is usually stronger than redirecting it.
Action 2: Set Up a 301 Redirect
A 301 redirect is the correct solution when content is moved to a new location. But it should only be used when there is a clear replacement page that satisfies the same intent as the original URL.
For example the slug of your old article was /technical-seo-guide-2023 which is also a wrong format and then you move it to /technical-seo-guide/ which is perfect. This is how you should do it.
Redirecting unrelated pages to the homepage is one of the fastest ways to trigger soft 404 classifications.
After implementing redirects:
- Test the old URL manually
- Confirm the redirect returns 301
- Verify the destination page returns 200
- Inspect the URL in Search Console
Action 3: Leave the 404 Alone
The most common mistake I have seen site owners make is to fix all the 404 not found errors. Many 404s should remain untouched. You do not need to do anything about them in many cases because they are usually spam-generated URLs or fake WordPress endpoints.
A few examples are like:
- /wp-admin/
- /xmlrpc.php
- /.env
- /backup.zip
Google’s John Mueller has repeatedly explained that 404s themselves are not a quality problem and are a normal part of the web ecosystem. If a URL has no value, no traffic, no backlinks, and no relevance, leaving the 404 is often the correct SEO decision.
Action 4: Return a 410 Gone
A 410 status code means this page was intentionally removed and is not coming back. In practice, Google treats 404 and 410 similarly for ranking purposes. The difference is mostly about crawl interpretation and deindexing behavior.
According to statements from Google representatives, the difference in removal speed between 404 and 410 is relatively small.
Use 410 only when the page was intentionally removed permanently. Do not use 410 for temporary removals or seasonal pages that may return later. Using 410 on pages that may return later can send confusing removal signals to Google.
How to Fix Soft 404 Errors
I made this mistake early in my SEO career too: redirecting too many deleted URLs to the homepage because it felt cleaner. In reality, it often turns a simple 404 issue into a soft 404 issue. A soft 404 happens when the page appears missing to Google even though the server technically returns a 200 OK response.
Google’s official documentation defines soft 404s as pages that look empty or contain thin placeholder content.
Common Causes of Soft 404s
- Redirecting deleted pages to the homepage
- Thin auto-generated tag pages
- Empty ecommerce categories
- Placeholder pages with no main content
- Expired product pages returning 200
How to Fix Them
- Return real 404 or 410 status codes for missing pages
- Redirect only to genuinely relevant pages
- Add substantial content to thin pages
- Remove empty indexable URLs from sitemaps
Do 404 Errors Waste Crawl Budget?
Yes, For most websites, crawl budget concerns around 404 errors are massively over-discussed.
That means a normal content site with a few hundred or few thousand 404s is unlikely to suffer measurable crawl-budget damage.
However, very large-scale 404 generation from broken faceted navigation, infinite parameter spaces, or malformed internal links can still create crawl inefficiency.
This becomes more important when reviewing recent deindexing patterns across SEO sites because unstable crawl behavior often appears together with indexing volatility.
What “Validate Fix” Actually Does?
One of the biggest misconceptions in Search Console is that clicking “Validate Fix” forces Google to immediately recrawl URLs.
It does not. Validate Fix simply tells Google I believe this issue has been addressed. Please verify during future crawls.”
The URLs disappear from reports only after Google naturally recrawls them and confirms the new state.
Depending on crawl frequency, this can take days or weeks.
Final Thoughts
The longer I have worked with Search Console, the more I have learned that not every warning is an emergency. 404 reports are a perfect example.
The job is not to make the report look clean. The job is to make the site easier for Google and users to understand.
Some missing URLs deserve recovery, some deserve consolidation, and many are simply normal web noise that Google expects to encounter.
Once you understand that distinction, managing even very large 404 reports becomes dramatically simpler.
