Every website eventually encounters 404 errors. Pages get deleted, URLs change, products sell out, and links are mistyped. A 404 error occurs when a user or search engine requests a page that does not exist on your server. While a few 404 errors are normal and not inherently harmful, unmanaged broken pages can create poor user experiences, waste crawl resources, and cause you to lose the value of backlinks pointing to those URLs. Knowing how to identify and fix 404 errors is an essential part of maintaining a healthy website.

What Is a 404 Error?
A 404 error is an HTTP status code indicating that the server could not find the requested page. It is different from server errors, which indicate a problem with the server itself. Users typically see a "Page Not Found" message. Search engines encountering 404 errors eventually drop those URLs from their index.
Do 404 Errors Hurt SEO?
Google has stated that 404 errors are a normal part of the web and do not directly harm a site's overall rankings. However, they can have indirect effects. If valuable pages with backlinks return 404 errors, the authority from those links is lost. Broken internal links waste crawl budget and create dead ends for users. A poor user experience can increase bounce rates and reduce conversions. Managing 404 errors protects both SEO value and user satisfaction.
How to Find 404 Errors
Several tools help you identify broken pages:
- Google Search Console: The Pages report shows URLs returning "Not found (404)."
- Website crawlers: Tools like Screaming Frog and Sitebulb find broken internal links.
- Backlink tools: Ahrefs and Semrush reveal external links pointing to broken pages.
- Analytics: Track visits to your 404 page to see which missing URLs users encounter.
Using several sources together provides the most complete picture.
Prioritize Which 404s to Fix
Not every 404 error needs attention. Prioritize based on impact. Focus first on URLs with backlinks from external sites, pages that previously received significant traffic, and broken links within your own site. URLs that never existed, such as random typos or spam requests, can usually be ignored. Prioritizing helps you spend time where it delivers the most value.
Fix 1: Implement 301 Redirects
When a page has moved or been replaced, use a 301 permanent redirect to send users and search engines to the most relevant new page. This preserves most of the link equity from the old URL. Choose the closest topical match rather than redirecting everything to the homepage. Mass redirects to irrelevant pages may be treated as soft 404s, which provide little SEO benefit.
Fix 2: Restore Valuable Content
If a page was deleted by mistake or still has value, consider restoring it. This is especially useful when the page had strong backlinks, traffic, or rankings. Restoring the content at its original URL immediately resolves the error and recovers its value.
Fix 3: Update Broken Internal Links
Internal links pointing to missing pages should be updated to point directly to the correct live URL. Relying on redirects for internal links adds unnecessary steps and slows down crawling. Use a crawler to identify every page that links to a broken URL, then update those links in your CMS.
Fix 4: Contact Sites with Broken Backlinks
If external websites link to a broken URL on your site, you can implement a redirect, but you can also ask the site owner to update their link to the correct page. This ensures the full value of the link reaches the right destination and improves the experience for their readers.
Fix 5: Let Unimportant Pages Return 404 or 410
Some pages are intentionally removed with no relevant replacement. In these cases, it is acceptable to let them return a 404, or use a 410 status code to indicate the page has been permanently removed. Search engines will eventually remove these URLs from their index. Do not redirect them to unrelated pages simply to avoid errors.
Create a Helpful Custom 404 Page
A custom 404 page improves user experience when visitors land on a missing page. Include a friendly message, a search bar, links to popular pages, and clear navigation options. Make sure the page returns a true 404 status code, not a 200 status code, to avoid creating soft 404 issues. A helpful error page keeps visitors on your site rather than losing them.
Prevent Future 404 Errors
Prevention is easier than repair. Set up redirects whenever you change URLs or delete pages. Plan site migrations carefully with complete redirect maps. Run regular crawls to catch broken links early, and monitor Search Console for new errors. Building these habits into your website maintenance process keeps errors under control. Ongoing technical care also supports your broader digital marketing efforts by ensuring every campaign sends users to working pages.
Final Thoughts
404 errors are a normal part of managing a website, but unmanaged broken pages can waste link equity, frustrate users, and reduce crawl efficiency. By finding errors regularly, prioritizing high-impact URLs, using proper redirects, updating internal links, and creating a helpful custom 404 page, you can protect your site's performance. Pairing these practices with professional search engine optimization keeps your website healthy and competitive.
