404 error pages

404 error pages occur when a user or search engine crawler tries to access a page on a website that does not exist. These pages are unavoidable, but how you handle them plays an important role in technical SEO. Well-designed 404 error pages can help to improve the user experience, while poorly managed 404 errors can impair crawlability and lead to a poor user experience.

Why 404 error pages matter for technical SEO

• Avoiding crawler problems: If search engine crawlers regularly hit pages that do not exist, this can lead to inefficient use of the crawl budget and impair the indexing of important pages.
• User experience: A well-designed 404 page can stop users from leaving the website in frustration by offering alternative content or navigation options.
• Avoiding ranking losses: Frequent 404 errors can have a negative effect on the overall performance of your website, as they point to poor maintenance and a lack of updates.

Best practices for 404 error pages in technical SEO

• Design custom 404 pages: Create a user-friendly, visually appealing 404 page that tells users the page they were looking for does not exist and offers alternatives such as a search or links to important pages.
• Sensible redirects: Use 301 redirects to send important or deleted pages that still receive traffic to relevant pages, protecting both the user experience and SEO performance.
• Regular monitoring of 404 errors: Use tools such as Google Search Console to check your website for 404 errors regularly and fix them promptly.
• Avoiding soft 404 errors: Soft 404 errors occur when a page is wrongly reported as having loaded successfully even though the content is missing. Make sure that real 404 pages are set up correctly and that redirects are used sensibly.
• Check internal links: Go through all internal links regularly to make sure they point to existing pages, and fix broken links that could lead to 404 errors.

Conclusion

404 error pages are unavoidable, but managing them properly is crucial for the usability and technical SEO performance of your website. By implementing well-designed 404 pages, checking for errors regularly and using sensible redirects, you can minimise the negative impact of 404 errors on your SEO rankings and improve the user experience.
