Definition
Error 404 (also called 404 Not Found) is an HTTP status code that indicates a webpage could not be found on the server. This error takes place when a user attempts to access a missing, deleted, or incorrectly linked page. While a 404 error does not mean the entire website is down, it can frustrate users and negatively impact SEO if not properly handled.
Why It Matters
A 404 error can hurt user experience, reduce website traffic, and impact search rankings if too many pages return this error. Common reasons for 404 errors include:
- Deleted or moved pages without proper redirection.
- Broken or mistyped URLs.
- Expired links from external sources.
- Website restructuring without updating links.
Properly handling 404 errors with custom error pages, redirects, and broken link management helps retain visitors and maintain SEO rankings.
How It’s Used
- Custom 404 Pages: Websites create branded 404 error pages with helpful navigation or search options.
- Redirects (301 & 302): Missing pages are redirected to relevant content to prevent dead ends.
- Broken Link Fixing: Regular audits identify and repair broken internal and external links.
- User Guidance: 404 pages often include links to the homepage or contact support.
- SEO Optimization: Google Search Console can detect 404 errors and suggest fixes.
Web developers use tools like Google Search Console, Screaming Frog, and Ahrefs to monitor and resolve 404 errors efficiently.
Example in Action
An e-commerce store removes an old product page, but customers still find it through search engines. Instead of showing a blank 404 error:
- They set up a 301 redirect to a related product page.
- They update internal links to avoid sending users to a missing page.
- Their custom 404 page suggests similar products to keep users engaged.
By properly handling 404 errors, they reduce bounce rates and improve user experience.
