Whenever, users click on a broken link that does not exist your web server will return a 404 is a HTTP status code indicating the requested URL is not found. This is a common problem on bigger sites due to various reasons. In this article we will explore the reasons for 404 error, why you should correct it and how to monitor 404 page not found errors in WordPress site.
Reasons for 404 Error Page
There are many reasons for the server to return 404 status code.
- You have changed the URL of a page or image to a new URL.
- Permanently deleted the page either due to outdated content or combined with another page.
- Moved the page to another domain or directory.
- Changed the structure of the URL due to change in hosting platform.
- Migrated site from one platform to another platform.
Especially for the larger sites having multiple editors modifying the content, there are many possible scenarios resulting in 404 errors. Also during migrating from one platform to another platform you may need to change the URL structure say from .html to no extension or .php.
Why Should You Correct 404 Error?
Every visit to a site is an opportunity for site owners to showcase the content and probably sell something. Merely displaying a 404 page will increase the cost of serving a webpage. Site owners should correct the 404 errors for the following reasons:
- Users landing on 404 page may be disappointed since they are not getting what was expected. This will drag the user’s confidence on the site owner’s ability to maintain the site and may not trust the site for purchasing products.
- Most of the hosting companies charge for page views which includes serving 404 pages to users.
Now you must have got the point!!! 404 pages not only going to hurt the user’s experience but also cost you for serving an error page.
How to Monitor 404 Errors on WordPress Site?

How to Correct 404 Error Pages?
Whenever you change the URL, correct way is to setup a 301 redirect and point the old URL to new URL. Since search engines take long time to replace the URLs on search results, setting up 301 redirects help crawlers to index the content on redirected page.
