404
Universal HTTP Status Code
Severity: MinorWhat Does This Error Mean?
A 404 Not Found error means the page you are looking for does not exist at that address. The server is working fine — it just cannot find that specific page. The page may have been deleted, moved, or the link you clicked may have a typo in it. This is one of the most common errors on the internet and it is completely harmless.
Affected Models
- All web browsers
- All websites
- Mobile browsers
- Search engine links
Common Causes
- The page was deleted and no longer exists on the website
- The page was moved to a new address without a redirect being set up
- You clicked a broken or outdated link — often from an old email or bookmark
- There is a typo in the URL you typed or copied
- The website recently redesigned and reorganized its pages
How to Fix It
-
Check the URL carefully. Look for typos, missing letters, or extra characters. Even one wrong letter gives a 404.
URLs are case-sensitive on some servers — 'About' and 'about' can be different pages.
-
Go back to the website's homepage and use the search bar or navigation menu to find the page you need.
The content you want may still exist — just at a different address.
-
Try searching for the page title in Google. Type: site:websitename.com followed by what you are looking for.
Google often has the correct current URL indexed.
-
Use the Wayback Machine at web.archive.org to see if the page ever existed and what was on it.
This is useful if you need content from a page that has been deleted.
-
If you followed a link from another website or email, let the sender know the link is broken.
Old links go dead all the time — a quick heads-up is always appreciated.
When to Call a Professional
As a visitor, there is not much a professional can do for you here. If you own the website and are seeing 404s in your analytics, a web developer can set up redirects from old URLs to the new pages.
Frequently Asked Questions
Does a 404 mean the whole website is down?
No — just that one page is missing. The rest of the website is working fine. If the entire site were down, you would see a different error like a 503.
Why does my bookmark show a 404 now?
The page was probably moved or deleted since you saved the bookmark. Websites change over time. Try searching for the content from the homepage.
Can a 404 page hurt a website's search ranking?
Yes — if a website has many broken pages, search engines may rank it lower. For visitors, though, a 404 is harmless and will not affect your device or data.
