1. Introduction

In the vast world of web development and digital marketing, every detail counts. From the aesthetics of your site to its performance and navigability, every aspect plays a vital role in shaping the user’s experience and your website’s visibility on search engines. Among these myriad considerations, the management of 404 errors holds a significant place. These seemingly inconvenient roadblocks can actually serve a crucial function when understood and handled appropriately.

1.1 Understanding 404 Errors

404 errors occur when a server cannot find the page that a user or search engine is attempting to access. This could be the result of a broken or dead link, a page that has been removed or moved without proper redirection, or a mistyped URL. When encountering a 404 error, the user is typically presented with a default error message, such as “404 Not Found,” which indicates that the requested resource could not be located on the server. More on 404 errors here.

In essence, a 404 error is the web’s way of saying, “The page you’re looking for can’t be found.” While these errors can be frustrating for users, especially if they’re seeking specific information or attempting to complete a purchase, they also offer an opportunity to provide a unique user experience, present options for navigation, and demonstrate the personality of your brand. Moz has some useful info on the subject of 404 errors.

1.2 The Impact of 404 Errors on SEO

While a few 404 errors aren’t likely to drastically affect your site’s search engine optimisation (SEO), a high frequency of these errors could potentially harm your site’s reputation with search engines and users alike.

From an SEO perspective, 404 errors can affect your website’s crawling, indexing, user experience, and the distribution of link equity. Search engines like Google strive to provide their users with the best possible results, which means leading users to functional and relevant pages. When search engine bots encounter a 404 error, they receive a signal that the page does not exist, and therefore, they cannot index the page or pass on link equity. This can prevent your page from appearing in search results, ultimately reducing your website’s visibility and traffic.

Moreover, consistent 404 errors can lead to a poor user experience. Users who frequently encounter these errors may become frustrated and perceive the website as unreliable or poorly maintained, which can diminish your brand’s reputation and deter visitors from returning.

However, it’s important to remember that not all 404 errors need to be fixed. Sometimes, they serve a useful purpose, such as when a page no longer exists, and you don’t want to redirect the user to a new page. The key is to manage these errors effectively and strategically to maintain an optimised web presence. In the following sections, we’ll delve deeper into the importance of 404 errors in SEO, how to identify them, and best practices for managing these errors effectively.

2. The Importance of 404 Errors in SEO

While it’s evident that 404 errors can present challenges, it’s crucial to comprehend their role in SEO to appropriately manage them. It’s a nuanced situation that isn’t merely about eradicating all 404 errors. In fact, they serve significant purposes in SEO and overall website health, from influencing user experience to affecting search engine crawling and link equity.

2.1 User Experience (UX)

To put it plainly, consistent 404 errors can be off-putting to users. Imagine eagerly clicking a link, expecting to find the information or product you desire, only to be met with a disappointing “Page Not Found” message. User Experience (UX) is an essential factor that search engines take into account when determining page rank, and excessive 404 errors can negatively affect UX and, consequently, SEO.

However, a well-handled 404 error can provide an opportunity to maintain a positive user experience. An engaging, informative, and user-friendly 404 page can lessen the blow of the missing content. This could be anything from a simple, clear message telling the user that the page doesn’t exist, to something more creative, such as a branded image, a search bar, or links back to popular pages on your site.

2.2 Search Engine Crawling and Indexing

Search engines navigate the web by crawling pages and following links from one page to another. This process allows them to discover new pages and index them in their massive databases, ready to be displayed in search results.

However, when a search engine crawler encounters a 404 error, it recognises that there’s nothing to index on that particular page. The crawler will move on to the next page, and the 404 page will not be included in the search engine’s index. This lack of indexing means that the 404 page will not appear in search engine results.

Repeated 404 errors can also lead to wasted crawl budget. Search engines allocate a certain amount of resources to crawl each website, known as the crawl budget. If a significant portion of this budget is spent on non-existent pages, it could potentially limit the discovery and indexing of your existing, valuable pages.

2.3 Link Equity and Authority

Another key component to consider is the impact of 404 errors on your website’s link equity and authority. When other sites link to your pages, they pass on a certain amount of link equity, which can positively influence your page’s search ranking.

However, if the linked page is removed or changed without a proper redirect, the link will lead to a 404 error. This results in a loss of link equity, as the authority that could have been passed on to your page is lost. Essentially, valuable links that could have bolstered your website’s credibility and search engine ranking are squandered.

Moreover, broken links leading to 404 errors can harm your site’s authority. A high number of broken links might signal to search engines and users alike that your site is poorly maintained or outdated, thus negatively impacting your site’s reputation.

In conclusion, 404 errors can significantly impact your website’s SEO if not handled appropriately. They affect user experience, search engine crawling and indexing, and the distribution of link equity. However, with strategic management, these errors can be transformed from potential hindrances into opportunities for maintaining an optimised, user-friendly website. In the following sections, we’ll explore how to identify 404 errors and the best practices for handling them efficiently.

3. Identifying 404 Errors

To manage 404 errors effectively, the first step is identifying them. Regular monitoring of your website can help you catch these errors promptly and address them before they escalate into bigger issues. Two popular tools for finding 404 errors are Google Search Console and site crawling tools.

3.1 Using Google Search Console

Google Search Console is a free tool provided by Google that helps you monitor and troubleshoot your website’s presence in Google Search results. It’s an invaluable tool for any website owner looking to optimise their site’s performance in Google Search.

One of the most powerful features of Google Search Console is the Coverage report. This report provides detailed information about the pages on your site that Google has tried to index. By checking the “Excluded” tab in the Coverage report, you can see pages that were excluded from Google’s index, often because of 404 errors.

If you notice an increase in 404 errors in your Coverage report, it’s essential to investigate these errors and resolve them if necessary. Google Search Console even provides the URLs of the pages where errors have occurred, making it easier for you to locate and address them.

Keep in mind that not all 404 errors reported in Google Search Console need to be fixed. For instance, if a page was intentionally removed and isn’t meant to be replaced or redirected, then a 404 error for that page is appropriate.

3.2 Site Crawling Tools

In addition to Google Search Console, there are various site crawling tools available that can help you identify 404 errors on your website. These tools work by mimicking the behaviour of search engine bots, crawling your website, and identifying issues like 404 errors.

One such tool is Screaming Frog’s SEO Spider, which provides a user-friendly interface for spotting 404 errors. After initiating a crawl, SEO Spider will list all the URLs on your site, along with their HTTP status codes. You can filter these results to show only the URLs that returned a 404 status code.

Other popular crawling tools include SEMrush, Ahrefs, and Moz, each offering their own unique features and capabilities. These tools can provide more in-depth analysis and can even detect broken links, which are a common cause of 404 errors.

Remember, consistent monitoring of 404 errors is vital. These errors can pop up at any time, for example, when old pages are deleted or when website updates result in changed URLs. Regular use of tools like Google Search Console and site crawlers will help you stay on top of these issues and maintain an optimised website.

In the next sections, we will look into the methods for properly handling 404 errors and the best practices for managing them.

4. Properly Handling 404 Errors

Once you have identified 404 errors on your site, the next step is determining how to address them. Your approach to this will largely depend on the nature and cause of each error. Remember, not every 404 error is a problem that needs fixing. Sometimes, it’s simply an indication that a page has been removed and should not be replaced or redirected. Nevertheless, there are several strategies you can employ to manage 404 errors effectively and minimise their impact on your SEO.

4.1 Creating a Custom 404 Error Page

When users encounter a 404 error on your website, they are typically served a default error page that may come across as abrupt or unhelpful. One effective way to minimise the impact of 404 errors on user experience is to create a custom 404 error page.

A well-designed 404 page can help retain users who might otherwise bounce from your site. By providing a friendly message, a search function, or links back to popular pages on your site, you can help users find what they’re looking for and continue their journey on your site.

Creative and engaging 404 pages can also showcase your brand’s personality and commitment to user experience. Whether you choose to use humour, unique illustrations, or interactive elements, your custom 404 page can turn a potentially frustrating experience into a memorable one.

4.2 Implementing 301 Redirects

A 301 redirect is a permanent redirect from one URL to another. If a page that previously existed on your site is deleted or moved and continues to receive traffic from old links, a 301 redirect can be used to guide users and search engines to a new, relevant page.

Implementing a 301 redirect can help you retain any link equity from the old page, as most of this equity is passed on to the new page. This can prevent a drop in your search engine rankings due to lost link equity.

While a 301 redirect can be an effective solution for managing 404 errors, it’s crucial to use them judiciously. Not every deleted page needs a redirect. If there is no suitable alternative page on your site, it might be better to serve a 404 error with a helpful error page.

4.3 Utilising the 410 Status Code

While a 404 status code tells search engines and users that a page is not found, a 410 status code communicates that the page is gone and is not expected to return. Essentially, a 410 status code sends a stronger signal to search engines that a page has been permanently removed.

Using a 410 status code can be particularly useful when you intentionally remove a page that no longer serves any value and you do not want to redirect it to another page. By using a 410 status code instead of a 404, you can help search engines understand more quickly that they should remove the page from their index.

In conclusion, managing 404 errors involves a careful evaluation of each error and implementing the most suitable strategy, whether it’s creating a custom 404 page, implementing a 301 redirect, or utilising a 410 status code. It’s about turning potential stumbling blocks into stepping stones, helping you provide a seamless user experience and maintain your website’s health and search engine ranking. In the next section, we will look at some best practices for managing 404 errors.

5. Best Practices for Managing 404 Errors

Effectively managing 404 errors is a crucial part of website maintenance that helps maintain the overall health of your site, supports a positive user experience, and safeguards your SEO efforts. By implementing some best practices, you can turn these seemingly problematic errors into opportunities for site improvement and optimisation. Our friends a Yoast have a good article on how to check and fix 404 errors.

5.1 Regular Monitoring for 404 Errors

As with many aspects of digital marketing and SEO, vigilance is key. Regularly monitoring your website for 404 errors allows you to catch and correct them before they have a chance to negatively impact your user experience or SEO rankings. Tools such as Google Search Console can be invaluable here, providing reports on 404 errors that search engine spiders encounter while crawling your site.

But remember, it’s not enough just to identify these errors; you need to investigate them, understand their causes, and develop appropriate solutions. By doing so, you can prevent their recurrence and enhance the overall robustness of your site.

5.2 Prioritising Errors on High Traffic Pages

While it’s important to fix all 404 errors, it’s equally important to prioritise. Errors on high-traffic pages or those with important backlinks should be addressed first as these can have a more significant impact on your SEO and user experience.

When a user or search engine encounters a 404 error on a high-traffic page, it’s a lost opportunity. The user is likely to leave your site, which increases your bounce rate, while search engines may consider the broken link as a signal of a poorly maintained site. Fix these errors as a priority to maintain the integrity of your site and the trust of your users and search engines alike.

5.3 Fixing Broken Links

Broken links are a common cause of 404 errors. These occur when a page is deleted or its URL is changed without updating the corresponding link. A user or search engine following this link will then encounter a 404 error.

Regularly auditing your site for broken links is a good habit. Once identified, these links should be fixed, either by updating the link if the page still exists at a different URL, or by removing the link if the page no longer exists. Another good practice is setting up redirects from your deleted pages to related pages on your site, preserving the user experience and the link equity these pages might have acquired.

Remember, managing 404 errors effectively isn’t a one-time task. It’s an ongoing process that, when done right, can significantly enhance your site’s user experience and SEO. So, embrace these best practices and turn the seemingly negative aspect of 404 errors into positive action for website optimisation.

6. Case Study: The Impact of Fixing 404 Errors on SEO Rankings

Understanding the theory behind 404 errors and SEO is one thing, but seeing its impact in practice can truly highlight the importance of managing these errors effectively. Let’s examine a real-world case study that demonstrates the positive effect of fixing 404 errors on a website’s SEO rankings.

The Company and the Problem

For the sake of confidentiality, let’s refer to our subject company as GreenThumb, an online retailer specialising in garden supplies. Despite their growing popularity and steadily increasing web traffic, GreenThumb noticed that they weren’t ranking as high as expected on search engine result pages for certain key phrases. On closer inspection, they identified an abundance of 404 errors as the possible culprit.

The errors arose from a recent website overhaul where many old and obsolete pages were removed. However, links to these pages from both within the website and from external sources were not updated or removed, leading to a host of 404 errors.

The Solution and Implementation

Understanding the severity of the situation, GreenThumb decided to tackle the problem head-on. They undertook a comprehensive audit of their website, using tools like Google Search Console and other SEO auditing software to identify and fix the 404 errors.

For pages that had been moved, they implemented 301 redirects to guide users and search engines to the updated page location. For pages that were permanently removed and had no suitable replacement, they utilised the 410 status code to signal to search engines that the page was gone intentionally.

The Outcome

Within weeks of addressing the 404 errors, GreenThumb saw a significant improvement in their SEO rankings for several keywords. Pages that were previously ranked lower due to 404 errors experienced a boost in their rankings, leading to increased visibility and web traffic.

Moreover, user engagement metrics such as time on site and pages per visit also improved, demonstrating that the effort to rectify 404 errors had a positive impact on user experience as well.

The Takeaway

This case study illustrates the potential SEO impact of 404 errors and the positive effects that come from fixing them. GreenThumb’s experience highlights the need for regular website audits, timely management of 404 errors, and the use of proper redirects.

Remember, 404 errors aren’t necessarily a bad thing – it’s how you handle them that makes the difference. Address them effectively, and you could turn a potential negative into a powerful positive for your SEO efforts.
