As you navigate the internet, you might encounter a message that says "404 Not Found." This error code is perhaps the most well-known of all HTTP status codes, and simply means that the server could not find what it was looking for. In this article, we will better explain what a 404 error is, what causes it, and example to show you what we mean.

What is a 404 Error?

A "404" error is an HTTP status code, indicating the server didn't find the page requested. That's for a variety of reasons:

The URL is mistyped.
The link to the page is broken.
The page has been moved or deleted.
The server is otherwise not responding.

In other words, when a user enters a URL that points to a page that doesn't exist, the server will respond with a 404 error and communicate to the user that the content was not found.

Why Do 404 Errors Occur?

There are many reasons why a 404 error may occur:

1. Typographical Errors: Users may mistakenly type or spell the URL incorrectly and land on a non-existent page.

2. Broken links: A site may link to a page, but that page no longer exists or is now somewhere else.

3. Website Redesign: If a website is redesigned, URLs typically change. The links on old content will still point to the now non-existent content.

4. Server Problems: Sometimes the server could just be down, or being reconfigured could cause 404 errors.

5. Expired Content: Content may be something that is not valid or useful anymore, and the author has just decided to delete it altogether.

Examples of 404 Errors

How to Handle 404 Errors

If you come across a 404 error, you may want to consider these options:

Check the URL: Double-check check there are no typing mistakes in the URL you entered.
Use Navigation: Go back to the homepage, or see whether the site has a navigation menu to locate the content you’re looking for.
Search Function: Use the site search to see if you can find the page you are looking for.
Contact Support: If you think the page truly does exist, then possibly reach out to the support email ID mentioned on the website header or footer.

404 errors are a normal part of the experience when browsing the web, but they can certainly be frustrating for users sometimes. If you understand what a 404 error is and what the possible reasons for one are, it will help you explore the web effectively.

Hard vs. Soft 404 Errors: What are the differences? How can you resolve them?

It is not uncommon to come across a 404 error while surfing the web. But there is a big difference in the types of 404 errors, and they can be broken down into two different types: "hard 404 errors" and "soft 404 errors." It is important for both webmasters and those within the web world to properly understand the differences between the two.

What is a Hard 404 Error?

A “hard 404 error” occurs when a server responds with a proper HTTP status code of 404. This means that the server acknowledges that the requested resource does not exist. The response is clear and indicates that the page is genuinely unavailable.

Characteristics of Hard 404 Errors:

HTTP Status Code: Returns a 404 status code.
Server Response: The server explicitly states that the requested resource cannot be found.
User Experience: Users typically see a standard or custom 404 error page.

Example:

When a user tries to access a deleted webpage, the server responds with:

HTTP/1.1 404 Not Found

What is a Soft 404 Error?

A “soft 404 error” occurs when a webpage appears to be a valid page but returns a 200 OK status code instead of the appropriate 404 status code. This can mislead both users and search engines, as the server indicates that the page is available when it is not.

Characteristics of Soft 404 Errors:

HTTP Status Code: Returns a 200 status code, even though the content indicates that the page is not found.
Server Response: The server does not acknowledge the absence of the resource correctly.
User Experience: Users may see a message stating that the page is not available, but the server still claims it is accessible.

Example:

A user accesses a page, and the server responds with:

HTTP/1.1 200 OK

However, the content might say, “This page is no longer available.”

Differences Between Hard and Soft 404 Errors

Feature	Hard 404 Error	Soft 404 Error
HTTP Status Code	404 Not Found	200 OK
Server Response	Clearly indicates the page is missing	Misleadingly indicates the page exists
Impact on SEO	Search engines understand the page is gone	Can confuse search engines, leading to indexing issues
User Experience	Users see a clear error message	Users may be misled into thinking the page is available

How to Resolve Hard and Soft 404 Errors

Resolving Hard 404 Errors

1. Create a custom 404 Page: Create a user-friendly 404 error page to help users get back to relevant/related content.

2. Redirect users: If it is relevant, set up redirects to help users to similar related content on your site.

3. Fix broken links: Regularly check for broken links on your site and take appropriate actions.

Resolving Soft 404 Errors

1. Update server settings: Make sure your server settings respond to nonexistent pages with an actual proper 404 status code.

2. Use error handling: Use server-side scripts to detect when a page does not exist, and return a 404 status code.

3. Watch your analytics: Watch for soft 404s in your website analytics, so you can figure out your corrective measures.

It is helpful to understand the difference between hard and soft 404s while maintaining your site. Hard 404s communicate a resource that is simply not there, whereas soft 404s can be confusing to both users and search engines. Though soft and hard 404s may not make the biggest difference in what you can do to help with your site's user experience, proper error handling and server setup can help users by correcting possible bad user experiences and help improve the site's SEO.
