Do 404 Errors Impact SEO Rankings?

404 errors may look pretty common yet frustrating for internet users. However, it is more daunting for SEOs and website owners.

In fact, this question- will 404 errors hurt SEO?- is repeatedly being asked somewhere or the other across the SEO community.

So, what’s all the noise around 404 errors? Are they a ranking signal and worth the hype? What does Google have to say about it all?

In this write-up, I will break down 404 errors in detail to help you get all of these questions regarding 404 errors answered.

Alright. Without any ado, let’s get started.

Understanding 404 Errors

A 404 error page is what the user sees when they attempt to visit a page that doesn’t exist on a website. It’s the computer’s way of saying that the requested page is not found.

So, what happens behind the scenes?

Imagine going to a grocery store to buy some eggs for breakfast. You ask the storekeeper and he first checks for the availability of the item and lets you know the status. That’s exactly how it goes between the browser and the server.

When the user enters a URL on their web browser, the browser goes to the website’s server and asks, “Hey, can I get this particular web page?“

When a user request comes in to visit a specific page on a website, the server returns an HTTP status code in response. In most cases, the server returns a 200 response code, which indicates that the user can access the content. I mean, if you are reading this blog post, it is because our server returned a 200 HTTP response code.

But what if the server can’t find the page anywhere? That’s when the 500 series errors and 404 error occurs.

SEO Impact of 404 Errors

404 error pages are pretty common and it is one of the most frequently encountered HTTPS errors across the web. The existence of a few 404 pages doesn’t affect your site’s overall performance and rankings.

As Google says, “The fact that some URLs on your site no longer exist or return 404 errors does not affect how your site’s other URLs (the ones that return 200 (Success) status codes) perform in our search results.”

However, it can impact your rankings if found in abundance and if the pages that return with 404 are integral to your website. Here are a few such scenarios in which you have to fix 404 errors on priority.

404 Error Impact on Backlinks and Authority

Imagine your website once had a highly successful page focused on marketing strategies during COVID-19. This page garnered significant organic traffic and high-quality backlinks. But now, as life normalizes and the content becomes less relevant, you’re considering removing this outdated post. However, there’s a catch.

When you delete this page, all those valuable backlinks will lead to a 404 error page, which can erode the authority your website has built. This is where strategic thinking comes into play.

Instead of outright removing the page, consider two better options:

Keep the Page: Sometimes, it’s wise to keep the page live. Even if it’s not drawing the same traffic, it still holds SEO value due to its backlinks.

Use a 301 Redirect: More effectively, you can replace the old content with something current and pertinent. For instance, create a new page about adaptable marketing strategies for future uncertainties. Then, 301 redirect the old COVID-19-focused page to this new one. This way, Google recognizes that you’ve updated your content to stay relevant, and the authority from the old page transfers to the new one.

This approach ensures you retain the SEO benefits and adapt to changing times without losing your site’s established authority.

SEO Impact of 404 Pages after Hack or Malware Attack

Indeed, there are scenarios where 404 errors can actually benefit your website, rather than harm it. Consider a situation where your website suffers a malware attack, resulting in hundreds or thousands of pages being wrongly indexed on Google. These pages might contain harmful content for users.

After successfully removing the malware from your server, it’s likely that these maliciously added pages will start showing 404 errors. In this case, it’s crucial not to automatically redirect these 404 pages to your homepage. This is a common mistake among webmasters. Instead, it’s advisable to leave these corrupted pages as 404s. Over time, which varies depending on the number of pages indexed, Google will recognize these pages as non-existent and remove them from its index. Implement a 301 redirect only for those pages that have contextually relevant and similar content.

Tips: If you want to remove the hacked pages from appearing on Google search, use the Temporary Removal tool in the search console.

What this means is that 404 errors on a less important and low traffic driving page will not lead to a negative impact on your overall website’s rankings.

Impact of 404 Errors on Website Bounce Rates

404 errors significantly increase website bounce rates. Typically, when users encounter a 404 error page, they are unlikely to explore further, perceiving the website as unreliable. This not only elevates bounce rates but also damages the website’s reputation.

Moreover, Google now factors in user engagement as a key aspect of SEO rankings. If visitors quickly exit a page, Google interprets this as the content not meeting user expectations, potentially leading to the page’s diminished visibility in search results.

Furthermore, encountering multiple 404 errors within a site, especially through internal links, severely disrupts the user experience. This not only ends the user’s journey abruptly but also negatively impacts the website’s standing with Google. Consequently, pages linked to 404 errors are less likely to achieve high rankings in search results, as Google aims to ensure a seamless experience for its users.

Effects of 404 Errors on Googlebot’s Crawl Efficiency

Googlebot, Google’s web crawler, scans websites to discover new and updated pages for indexing. However, a website with numerous 404 error pages can exhaust its allocated crawl budget. This overuse of resources may result in significant pages being overlooked during crawling, delaying their indexing.

Common Causes of 404 Errors

So, what triggers 404 errors? Here’s a look at the most common causes.

Broken Links

Broken links are born when a page is not properly linked to the destination URL. Misspelled URLs are one of the most common reasons behind the existence of broken links. When this happens, the user doesn’t get redirected to the page you want them to land on. Instead, they find themselves on a 404 error page.

Deleted or Moved Pages

If you move your content to a new destination or delete it altogether but don’t remove the old URL from whichever pages you placed them, you are driving your users to a 404 error page.

URL Changes

URL changes can be another catalyst for the appearance of 404 pages. If you update your page URL but fail to change it in your content where you have placed links to that particular page, you drive users to a non-existent page and open doors to 404.

How to Identify 404 Errors on Your Website

To weed out 404 errors on your website, you need to know where they exist in the first place. Here’s a look at the ways you can execute it.

Google Search Console

If Google finds 404 errors when crawling your site, it will notify the same via the Coverage Report in Google Search Console.

Similarly, once you fix the errors on your website, you can use the Validate Fix option in Google Search Console to bring it to Google’s notice in order to prompt the search engine to recrawl your site and evaluate the bug fixes you have made.

And that brings us to this question. What does Google do to validate fixed 404 errors? Nevertheless, it will still remain a 404 page. So, what actually happens behind the scenes?

Replying to a similar question on X, John Mueller, Senior Search Analyst / Search Relations team lead at Google, wrote, “It’s more if you accidentally 404’d something and fixed it. You obviously don’t have to fix 404s that you want to be 404s. Also, this is more about tracking for you (“I fixed this, tell me when you see it fixed too”).”

From what he says, validation of fixed 404 errors is more about keeping track of fixes for web pages that accidentally disappeared. After all, you don’t have to do anything about pages you intentionally don’t want to exist, right?

In other words, the 404 status code is not necessarily a bug that a webmaster has to fix. It is just that Google leverages the Validate Fix feature to keep an eye on missing pages in order to show them in SERPs once or if they return.

Semrush

The Semrush Site Audit tool comes in handy to crawl your website and identify potential on-page and technical issues lurking on your site.  Using this tool is a good way to identify 404 errors on your website.

Screaming Frog

Screaming Frog is another great tool to audit your site and locate on-page issues easily. Once the tool finishes crawling your site, navigate to Client Error (4xx) under Response Codes in the drop-down menu. That should help you narrow down 404 errors on your website.

Manual Checks

Checking your web pages manually for 404 errors may be time-consuming. However, it is a good way to double-check and fix 404 errors and other potential problems on your website.

How to Fix 404 Errors

Now that you know how to identify 404 errors on your website, let’s get to how to fix them.

Setting Up 301 Redirects

301 redirects allow users to automatically redirect to the new destination when they are about to land on a page that doesn’t exist anymore. This way, you stop your visitors from hitting a 404 dead end.

So, how do you do it?

• Install a trusted free redirection plugin for WordPress
• On WordPress, go to Settings and navigate to the 404 tab
• Check for issues and, in the Redirect section, enter the URLs from which you want to redirect users
• Enter the new URLs in the Destination tab and save the changes

Updating Internal and External Links

Check your internal links carefully and identify the ones that lead to 404 pages. Replace them with new URLs to make sure your visitors are taken to the right pages on your website. This paves the way for improved user experience within your website.

On the other hand, updating external links that bring users from another site to a 404 page on your site takes a bit more work. Unlike internal pages that are completely in your control, your external links are placed on sites that are owned by others.

To fix such incoming 404 errors, you have to get in touch with corresponding webmasters with a genuine email pitch to replace your old URL with the new one or a link removal request in case of deleted pages that don’t have an alternative.

Creating an Effective Custom 404 Page

Rectifying 404 errors strengthens your website’s SEO. However, it is not always possible to eliminate 404 errors because certain factors, like a user typing a misspelled URL, are out of your control. That’s why it is essential to create a custom 404 page for your website.

You can do this by using a free plugin for custom 404 page creation. In your custom 404 page, you can include elements like a search box, links to important pages on your website and your contact information.

Such a 404 page is user-friendly because it provides visitors with potential options to search for and explore relevant sources and interact with your website.

Monitoring 404 Error Pages

It is good to monitor your site from time to time for potential 404 errors, especially when you update parts of your website or revamp it entirely.

As I mentioned earlier, you can use tools like Google Search Console, Semrush Site Audit Tool, Screaming Frog and more to identify and fix 404 errors.

By monitoring your site from time to time, you can take steps to fix visible 404 errors at the earliest, even if not root them out completely.

What is the Difference Between Hard 404 and Soft 404?

Want to delve deep into 404 errors? Here comes Hard 404 Vs. Soft 404.

Hard 404 is the usual 404 error we’ve discussed above. If the page doesn’t exist, the server returns a 404 error code.

On the flip side, soft 404 error pages return a 200 OK status code, which means it is alright for the search engine to crawl and index corresponding web pages. This will be a waste of the crawl budget Google has allocated for your site.

As a result, soft 404 pages may exhaust your crawl budget and prevent Google from crawling and indexing your important pages faster.  It is important to note that the soft 404 error pages come with thin content and page loading issues.

Plus, as these pages don’t return a 404 error code, it is pretty difficult to detect these pages using SEO tools.

All these said, soft 404 pages are a threat to your website’s health and SEO.

404 errors are quite common. However, if you let them spread across your website, they are strong enough to affect your user experience and even bring down your domain authority and Google rankings in the long run. That means, if ignored, 404 errors can harm your website’s SEO seriously.

Put the methods I have suggested above into practice in order to identify and fix 404 errors as much as possible. Make sure you follow the best practices and monitor your site for 404 errors to offer a great user experience to your visitors and take another step towards securing a stronger spot in the good books of Google.
