How to Fix 404 Error for SEO: Simple Steps to Improve Your Site

A 404 error happens when a page is missing or moved without a redirect. To fix it for SEO, find broken URLs and set up 301 redirects to relevant pages or restore the missing content. This helps search engines and users find the right pages and improves your site's ranking.

Why This Happens

A 404 error occurs when a user or search engine tries to visit a page that no longer exists or has been moved without proper redirection. This can happen if you delete a page, change its URL, or have broken links on your site or from other sites.

Search engines see 404 errors as bad user experience and may lower your site's ranking if many pages return 404.

html

<a href="/old-page">Old Page</a>

Output

Clicking this link leads to a 404 Not Found error page because /old-page does not exist.

The Fix

To fix 404 errors for SEO, identify all broken URLs using tools like Google Search Console or website crawlers. Then, set up 301 redirects from the broken URLs to the correct or most relevant pages. This tells search engines the page has moved permanently and transfers SEO value.

If the page was deleted intentionally and no replacement exists, create a custom 404 page that helps users find other content.

apache

RewriteEngine On
Redirect 301 /old-page /new-page

Output

Visiting /old-page automatically redirects to /new-page with a 301 status, fixing the 404 error.

Prevention

Prevent 404 errors by maintaining a clear URL structure and updating internal links whenever URLs change. Use website audit tools regularly to catch broken links early. Always implement 301 redirects when removing or moving pages.

Also, create a helpful custom 404 page that guides visitors back to useful content, improving user experience and SEO.

Related Errors

Other common SEO errors include:

• Soft 404: Pages that show 'not found' messages but return a 200 OK status, confusing search engines.
• 500 Server Errors: Temporary server problems that block page access.
• Redirect Loops: Redirects that point to each other endlessly, causing errors.

Fix these by ensuring correct HTTP status codes and proper redirect rules.
