How does a 404 error affect SEO?

Error 404, also known as “Not Found,” can have a significant impact on a website’s SEO rankings. This occurs when the server cannot find the requested page. Often servers do not return the correct 404 response, and this disrupts the process of site indexing by search engines and also worsens the user experience. All of these issues can lead to a negative impact on a website's ranking.

What is a 404 error?

Error 404 is a standard HTTP code that the server sends in response to requests for non-existent pages. This code tells search engines and users that the requested page was not found.

The code consists of three digits, each of which has its own meaning:

• The first number (4) indicates an error that occurs on the client side.
• A zero indicates that the problem is not with the request syntax.
• The last number (4) indicates that the page does not exist.

Why does a 404 error occur?

Error 404 can occur for a number of reasons, such as:

• Incorrectly entered URL in the browser address bar.
• Following a broken link that leads to a non-existent page.
• The page has been removed from the site, but the link to it remains.
• The page was moved to another address and the redirect was not configured.

What does a 404 error mean for SEO?

If the server returns a 200 OK code instead of a 404 for pages that don't exist, it can mislead search engines into telling them that the page exists. This error makes it difficult to properly index the site and can worsen its ranking in search engines.

How to provide a 404 Not Found response?

For most popular CMS systems, problems with processing 404 errors will not arise. However, it is important to ensure that the server correctly handles requests for non-existent pages. If the server returns an incorrect code, you must contact the technical support of your hosting provider or configure the server manually.

How to make a 404 page?

It is recommended to create your own error pages that will blend harmoniously with the site design.

To bring them into line with best practices, it is enough to have access to -files.

How to design a 404 page?

Even though the 404 page is an error page, it should be designed in accordance with the overall design of the site. Poorly designed error pages can influence user behavior, making navigation difficult.

To prevent an error page from causing bad behavior, there are a few key rules to follow:

• The page content must clearly inform the user that the requested page does not exist. In the page title (H1), you can include a phrase like “Page not found” and add an appropriate explanation.
• The error page must have navigation elements, such as a link to the site's home page or menu, so that the user can easily continue searching for the information they need.
• The 404 page should be styled in the same style as the rest of the pages on the site. This allows the user to have no doubt that he is on the right resource.

Following these principles will help not only improve the usability of the site, but also avoid the negative impact of the 404 error on SEO positions.
