Should you return a 204 or a 404 status code? When managing a website, choosing the correct HTTP status code is crucial for user experience and SEO. A 204 status code indicates a successful request with no content, while a 404 status code signals that a resource was not found. Selecting the appropriate code depends on the situation and the message you want to convey to users and search engines.
What is a 204 Status Code?
A 204 No Content status code is used when a server successfully processes a request but does not need to return any content. This can be useful in specific scenarios:
- When an action is completed without needing to refresh the page.
- For background updates where a response is unnecessary.
- For APIs that execute commands without returning data.
Using a 204 status code can improve user experience by reducing unnecessary data transfer and keeping the user interface clean and responsive.
When Should You Use a 404 Status Code?
A 404 Not Found status code is used when the server cannot find the requested resource. This is important for both users and search engines:
- Alerts users that the page or resource is unavailable.
- Helps search engines identify broken links.
- Encourages webmasters to fix or redirect broken URLs.
Using a 404 status code is essential when a page has been removed or never existed. It informs users and search engines that the resource is not available, prompting appropriate actions.
Comparing 204 and 404 Status Codes
| Feature | 204 No Content | 404 Not Found |
|---|---|---|
| Purpose | Successful request without content | Resource not found |
| User Experience | No page reload, seamless interaction | Informs of missing content |
| SEO Impact | Neutral, as no content is indexed | Alerts search engines to remove or de-index |
How Does Each Status Code Affect SEO?
SEO Impact of 204 Status Code
The 204 status code has a neutral impact on SEO. Since no content is returned, there is nothing for search engines to index. It is vital to use this code only when no content is needed, ensuring that users and search engines receive the correct signals about the page’s purpose.
SEO Impact of 404 Status Code
A 404 status code can have a significant impact on SEO. It informs search engines that a page is unavailable, prompting them to de-index the URL. This helps maintain a clean index and ensures users do not encounter broken links. However, excessive 404 errors may indicate poor site maintenance, potentially affecting the site’s overall ranking.
Practical Examples of Using 204 and 404 Status Codes
Example of 204 Status Code Usage
Consider a web application where users can update their profile settings. After submitting changes, the server processes the request and returns a 204 status code. This indicates that the update was successful without needing to refresh the page or return additional data.
Example of 404 Status Code Usage
Imagine a blog post that has been permanently removed. If a user attempts to access the URL, the server should return a 404 status code. This informs users and search engines that the page is no longer available, prompting users to navigate elsewhere and search engines to update their indexes.

What is the difference between 204 and 200 status codes?
The 204 status code indicates a successful request with no content, while a 200 status code signifies a successful request with content. Use 204 when no response body is needed, and 200 when you want to return data to the client.
How do 404 errors affect website performance?
404 errors can negatively impact website performance by leading to a poor user experience and potential SEO issues. Regularly monitoring and fixing broken links can improve site usability and search engine rankings.
Can a 204 status code be cached?
Yes, a 204 status code can be cached. However, since it does not return content, caching is often unnecessary. If caching is implemented, ensure it aligns with the intended user experience and application functionality.
When should I redirect instead of using a 404 status code?
Consider redirecting when a page has moved to a new URL or when similar content is available elsewhere on the site. Redirects can improve user experience by guiding visitors to relevant content, maintaining SEO value.
How can I monitor 404 errors on my website?
Use tools like Google Search Console or web analytics platforms to monitor 404 errors. These tools provide insights into broken links and help you identify opportunities for redirects or content updates.

Choosing between a 204 and 404 status code depends on the specific scenario and the message you want to convey.
