What Is a 404 Error?
A 404 error is an HTTP status code that tells browsers and search engines a webpage cannot be found on the server.
When a user or search engine crawler requests a URL that no longer exists the server responds with a 404 Not Found status.
Common reasons for 404 errors include:
- Deleted webpages
- Broken internal links
- Incorrect URLs
- Changed website structure
- Typing mistakes
- Removed products or blog posts
- Migration issues
- Broken backlinks
404 pages are a normal part of the internet because websites constantly update remove or restructure content.
Are 404 Errors Bad for SEO?
404 errors are not automatically bad for SEO. Google has repeatedly stated that normal 404 pages do not directly hurt rankings.
However they become problematic when they affect user experience website crawling or valuable backlinks.
The SEO impact depends on:
- Number of 404 errors
- Importance of missing pages
- Internal linking issues
- Backlink value
- Website maintenance quality
- Crawl efficiency
A few 404 pages are completely normal. Hundreds of broken pages can become an SEO problem.
How Google Handles 404 Errors
Google understands that webpages change over time.
When Googlebot encounters a 404 page it usually:
- Removes the URL from the search index
- Stops crawling the missing page over time
- Redirects crawl resources elsewhere
Google does not penalize websites simply for having 404 pages.
In fact returning a real 404 status is often better than showing incorrect content or redirecting users unnecessarily.
Properly handled 404 pages help search engines understand which content should no longer exist.
When 404 Errors Become Bad for SEO
404 errors become harmful when they interfere with website quality crawling and user satisfaction.
1. Poor User Experience
User experience is one of the most important SEO factors.
When visitors land on broken pages they may:
- Leave the website immediately
- Lose trust in the brand
- Become frustrated
- Increase bounce rates
A poor experience can reduce engagement signals and conversions.
2. Lost Link Equity
Backlinks are valuable for SEO.
If a deleted page previously had backlinks from authoritative websites the SEO value may be lost if the page returns a 404 error without a redirect.
This means:
- Lost authority
- Reduced rankings
- Decreased referral traffic
Redirecting valuable expired pages helps preserve link equity.
3. Crawl Budget Waste
Search engines allocate a crawl budget to websites.
If Googlebot spends too much time crawling broken URLs it may reduce crawling efficiency for important pages.
Large websites with many 404 errors can experience:
- Slower indexing
- Reduced crawl efficiency
- Delayed content discovery
4. Broken Internal Links
Internal linking helps search engines understand website structure.
Broken internal links leading to 404 pages create navigation problems and weaken SEO architecture.
This can negatively impact:
- Crawl paths
- User navigation
- Page authority distribution
- Content discoverability
5. E-Commerce SEO Problems
For eCommerce websites product pages often generate 404 errors when products are removed.
If not managed properly this can lead to:

- Poor shopping experience
- Reduced sales
- Broken category structures
Expired products should often use redirects or alternative recommendations.

Examples include:
- Empty pages with not found text
- Redirecting all pages to the homepage
- Thin content pages
Soft 404s confuse search engines and can negatively affect indexing.
Hard 404 Error
A hard 404 is a proper server response confirming the page is missing.
This is the preferred approach when content is permanently removed without replacement.

However they can indirectly impact SEO performance through:
