A 404 error is an HTTP error code sent by a web server when the requested resource is not available or the server cannot find the resource. 😮 Generally, this is a site that does not exist or no longer exists.

It’s not uncommon to find 404 errors on your website, and they’re easy to spot. When a 404 error prevents a user from browsing, a “404 File Not Found” error message often appears to inform the user.

Depending on your browser, 404 errors may be called something different: 👇

  • “404 Not Found”: the page you are looking for cannot be found,
  • “The requested URL cannot be found on this server”,
  • “HTTP 404”,
  • “HTTP 404 Not Found”,
  • “404 – File or directory not found”.

How do you avoid an HTTP error 404 page?

To avoid an HTTP error page, you can follow these tips
  • Check the URLs of your web pages before publishing them.
  • Don’t delete web pages without redirecting users to a new page.
  • If you move a web page, make sure you redirect users to the new page.
  • Keep your server in good condition.

In general, 404 errors do not adversely affect your site’s performance in search results. If you are sure that these URLs do not appear on your website, you can safely ignore them. 😉

However, it’s important to ensure that these invalid URLs and others return valid HTTP 404 response codes and are not blocked by your site’s robots.txt file. 🤖 Here’s how to deal with 404 errors: 👇

  • Decide whether you want to correct the error. Many, if not most, 404 errors can be ignored as they do not affect your site’s indexing or ranking. Please correct it if the URL has been sent to Google (Error).
  • If a page is deleted and there is no replacement or equivalent page, a 404 error is displayed. After about a month, you should no longer see 404 errors in your reports.
  • If the URL was generated by a script or never existed on your site, you probably don’t need to worry. It can be frustrating when you see this error in your reports, but unless the URL reports a link that is often misspelled, there is no need to correct it.
  • If the URL contains words or elements that are often misspelled or spelled differently. For example, “” (note the extra ‘l’ in ‘cancelling’) instead of “”.


What effect does a 404 error page have on SEO?

A “Not Found” 404 error can have a negative impact on your website’s SEO. 🙈 This is because search engines perceive 404 errors as a sign of a poor quality website.
This can lead to a drop in your website’s ranking in search results! 👎
  • However, your e-reputation drops when you delete a page with external links; the 404 page loses the popularity it had on the site.
  • Affects the quality of the indexing robot’s crawl. So if your website contains a lot of web pages with 404 errors, the indexing robot will crawl resources (web pages that are not relevant), when it could be crawling web pages that are essential to your SEO strategy.
  • Poor user experience. 404 errors can easily “irritate” web users when they are browsing websites. To overcome a poor user experience, you should consider customizing your 404 error page.
There are many myths and rumors about this, but Google does not penalize websites with too many 404 pages 🙂 However, they can have a negative impact on SEO for a variety of reasons: ⏬
  • Indexing problem: Google does not index pages containing 404 errors. This is untapped potential on your website.
  • Loss of “link juice”: backlinks are external links that point to your website. They give Google power and importance. If your backlink points to a 404 page, you lose all your precious benefits.
  • Wasted crawling budget: Google’s crawlers generally don’t waste time crawling websites. Crawling time is limited. When Googlebot spends time on a 404 page, that time is wasted.
  • Internal linking problems: understanding your website and how search engines link to it internally is essential for your SEO.

In conclusion, 404 errors can make your site difficult to crawl and have a negative impact on SEO. 🙈
