Nothing sends a visitor away faster than clicking a link and landing on a page that no longer exists. A 404 error is one of the most common technical issues on the web — and one of the easiest to actually fix, once you know where to look.
What Is a 404 Error?
A 404 “Not Found” error appears when a visitor (or search engine) requests a URL that the server cannot find. It usually means the page was deleted, moved, or the URL was typed or linked incorrectly.
Why 404 Errors Matter for SEO
A reasonable number of 404s is completely normal for any website — Google does not penalize a site simply for having some. The real damage happens when: important pages that used to rank now return 404s (losing all their accumulated ranking value), internal links across your own site point to broken pages, or a large volume of 404s signals a poorly maintained site during a crawl.
A 404 on a page nobody linked to is a shrug. A 404 on a page that used to rank on page one of Google, with active backlinks pointing to it, is a real SEO loss.
How to Find 404 Errors on Your Site
- Google Search Console — the Coverage/Indexing report lists pages returning 404 that Google has tried to crawl.
- Site audit tools — crawl your entire site to catch broken internal links proactively.
- Your site’s error logs — many hosting panels log 404 requests directly.
How to Fix a 404 Error
- If the page moved or was renamed: set up a 301 redirect from the old URL to the new one, preserving any accumulated ranking value.
- If the page was intentionally removed with no replacement: redirect it to the most relevant existing page (like a parent category), rather than leaving a dead end.
- If it was a broken internal link: simply fix the link on the page that pointed to it.
- If it is a genuinely gone, low-value page: a clean, helpful custom 404 page with clear navigation is an acceptable outcome — not everything needs a redirect.

Designing a Helpful Custom 404 Page
A good 404 page keeps a visitor on your site instead of losing them: a clear message, a search bar, and links back to your homepage or most popular pages all meaningfully reduce lost traffic from unavoidable broken links.
Frequently Asked Questions
Do 404 errors hurt my overall site ranking?
Not directly or in bulk — but 404s on previously-ranking, well-linked pages do lose that specific page’s accumulated value.
Should every 404 be redirected?
No — only redirect to genuinely relevant destinations. Redirecting everything to your homepage is a common overcorrection that confuses both users and search engines.
How often should I check for 404 errors?
A monthly check via Google Search Console is a reasonable habit for most small business websites.
