A 404 error is a page not found error. This is a common error and means that you clicked on a broken link or typed in a website address that cannot be found. The error appears when you land on a missing page within a website that is running. A different error occurs when an entire website is down.
Why do 404 errors occur?
404 errors can occur when the navigation of a website changes or a page is removed. A link is considered broken if a page is removed or the website address for that page changes and a redirect link isn’t created.
Why should a marketer care?
It is important for a marketing professional to clean up 404 links because they can be a sign of a low-quality website, which can result in lower search engine rankings. It can also provide a poor user experience, causing users to navigate away from the site. This results in a higher bounce rate and a negative effect on website traffic.
How to fix 404 errors
Broken links can be found by manually testing the links within a website or using a service that regularly runs a check and provides a report of any broken links. When a broken link is found you should remove it or replace it with a working link. A 301-redirect can also be used to bring users to a different page of your website.
