Impact of Error 404 on a Website

Technically, error 404 isn’t harmful to websites. But the impact of error 404 is surely not good for your website rankings and traffic. The two key factors of a website that get affected by error 404 are user experience (UX) and SEO. Here’s how error 404 affects a website:

  • User Experience (UX)

UX is related to the experience of a user while visiting a website. The UX of a website defines how easy it is for a user to browse and interact with a website. When you access a specific page of a website and encounter an error 404, it leaves you irked and you are likely to leave the website.

  • Search Engine Ranking and Performance

Google’s official stance to pages with error 404  is neutral. Google touts it as an organic aspect of a website and it makes no difference to the ranking of a website or web page. However, the presence of 404s can directly influence the ranking of a website in a negative way. 

When a user is directed to a web page that displays error 404, Google perceives that the web page is not available anymore and removes the page from its search index. It lowers the PageRank from links referring to the page, leaving the links worthless.

If there are plenty of links referring to inactive or non-existent pages on a website that yields 404 errors, you can lose out on PageRank.

Types of error 404

Usually, there are three types of 404 errors that are mentioned below:

1. External 404s

This type of 404 error occurs when an external site has a non-functional link; either if it has been moved or the content has been removed.

2. Outgoing 404s

This kind of 404 error occurs whenever a link from your site to any other site breaks either due to another site’s content removal or the error in the link address. Links always vaporize and have no control over other site’s content. Therefore, outgoing 404 errors are not uncommon. Frequent site assessment helps you to remain at the top of your outgoing links to ensure that they are reaching the intended page.

3. Internal 404s

Internal 404 error occurs when a site is trying to link to some other page of your website that is non-existent. Apart from manually assessing whether the internal links are working or not, you can use dedicated tools to check your site for any internal 404 errors automatically. Broken Link Checker, Google Webmaster Tools, Screaming Frog, etc. are some of the tools to check for internal 404s errors.

How to Fix Error 404?

Identifying the 404 error is one aspect but what one needs to know is how to fix the error. Not all error monitoring and link checker tools accomplish this task.

These terms are sometimes used interchangeably but they are certainly two different things. Cookies refer to tiny chunks of information that point out where you are located on a given site, what you like about the site, and the time spent on the website, etc. Whereas cache deals with creating temporary copies of images and other website content so that the website can load faster. However, as the size of the cache of different websites stored altogether increases, it hampers the operation speed of the browser. Clearing the cache of a browser boosts the speed of the browser. Before clearing cache, one must check the browser settings to assure that the passwords never get cleared by any means. Also, you can try clearing the browser cookies as sometimes they can also hamper the accessibility of websites.

  • Redirect the Page

The quickest and most efficient way to fix a 404 error code is to automatically redirect a user from the page with error 404 to another web page that is working fine. This task can be performed by using a 301 redirection. The 301 redirect is another HTTP response code that indicates to a browser that the required content has been transferred to another URL address.

  • Correct the Link

Making errors while typing a URL address is common and this may cause you to encounter a 404 error. In such a case, you need to cross-check if the URL you have typed is correct.

  • Restore Deleted Pages

Often while browsing, people might be searching for a webpage on your website that you may have deleted. Even external links prompt the audience to that specific webpage. You can always redeem a deleted page to resolve the issue. However, if you have deleted the page unintentionally, you have to restore it or redirect the users accessing the deleted page to another one having similar content.
