The ‘404 Not Found’ error is one of the most recognizable HTTP status codes that can significantly impact your SEO efforts. When a webpage is not found, web browsers display this error message, leading to a poor user experience and affecting a site’s search engine rankings. In this article, we will delve into the intricacies of the ‘404 Not Found’ error in NGINX, its implications for SEO, and how to effectively handle it, especially in the context of API services like AI Gateway, the usage of Oauth 2.0, and how they relate to common issues like this.
Understanding HTTP Status Codes
Before we dive into ‘404 Not Found’, it’s essential to understand what HTTP status codes are. These codes are issued by a server in response to a client’s request made to the server. They are divided into five categories:
- 1xx Informational – Indicating that a request has been received and the process is continuing.
- 2xx Success – Indicating that the request was received, understood, and accepted.
- 3xx Redirection – Indicating that further action needs to be taken to complete a request.
- 4xx Client Error – Indicating that the request contains bad syntax or cannot be fulfilled.
- 5xx Server Error – Indicating that the server failed to fulfill a valid request.
The ‘404 Not Found’ error falls under the 4xx category, specifically indicating that the server cannot find the requested resource.
What Does ‘404 Not Found’ Mean in NGINX?
When your NGINX server returns a ‘404 Not Found’ error, it means that the requested URL does not exist on the server. This situation can arise due to several reasons:
- The URL was mistyped by the user.
- The content was removed or relocated without updating the links.
- The server configuration does not recognize the requested resource.
Each time a ‘404 Not Found’ error occurs, it can lead to a poor user experience and can also hinder your site’s search engine rankings, making it crucial to manage this error effectively.
The Implications of ‘404 Not Found’ on SEO
Negative Impact on User Experience
User satisfaction is critical for any website. Encountering a ‘404 Not Found’ page can frustrate visitors, leading them to leave your site. High bounce rates can signal to search engines that your website is not providing value.
Effects on Crawl Budget
Search engines allocate a crawl budget to each site, which represents the number of pages the search engine’s crawler will visit. If crawlers land on numerous ‘404 Not Found’ pages, they may run out of time or resources to index the relevant pages on your site. This situation can ultimately lead to decreased visibility in search results.
Link Equity Loss
If other sites link to a page that returns a ‘404 Not Found’, you lose potential link equity, which may affect your overall SEO standing. Backlinks are crucial for building domain authority, and when they lead to non-existent pages, it can hamper your SEO efforts.
Handling the ‘404 Not Found’ Error
Custom 404 Pages
One effective strategy is to create a custom ‘404 Not Found’ page. This page should include components such as:
- An apology for the inconvenience.
- Navigation options to guide users back to relevant content.
- A search bar to encourage users to find what they were looking for.
By doing this, users still receive a positive experience even when they encounter a ‘404 Not Found’ error.
Monitoring and Errors Management
Use tools like Google Search Console and Bing Webmaster Tools to monitor ‘404 Not Found’ errors on your site. Identifying and fixing these broken links can significantly improve your site’s overall health.
Redirecting URLs
For pages that have moved or been updated, implementing a 301 redirect can help maintain your link equity and provide users with an alternative path to access content. Make sure to avoid redirect chains, as they can degrade your SEO performance.

Leveraging Log Analysis
Utilize your server logs to identify frequent ‘404 Not Found’ errors. Analyzing these logs can assist in pinpointing problematic URLs that require attention. This proactive approach helps maintain a clean and user-friendly website.
| URL Status Codes | Description | SEO Impact |
|---|---|---|
| 200 OK | The request has succeeded. | Positive impact |
| 301 Moved Permanently | Content has been permanently moved. | Neutral to positive |
| 404 Not Found | The requested resource could not be found. | Negative impact |
| 500 Internal Server Error | The server encountered an error. | Major negative impact |
The Role of AI Gateway in Handling Errors
Leveraging AI technologies has become crucial in understanding and addressing user requests efficiently. Through platforms like AI Gateway (aigateway.app), you can enhance user interaction by providing actionable insights whenever a ‘404 Not Found’ error occurs. Integrating AI into user service can allow for natural language processing capabilities to handle user inquiries about missing pages.
Implementing Oauth 2.0 in API Calls
When utilizing APIs, implementing Oauth 2.0 for authentication is critical. If an endpoint protected with Oauth 2.0 is incorrectly accessed, it might also return a ‘404 Not Found’ due to incorrect URL or authorization issues. Ensuring secure and correct endpoint access is crucial to minimizing errors in API service calls.
For example, if you have a service path that specifies certain conditions for access that aren’t met by a user’s request, you’d return a ‘404 Not Found’ due to those access restrictions. Ensuring your API and resource links are documented clear will greatly help mitigate issues here.
# Example: Simple API call with Oauth 2.0
curl --location 'http://example.com/api/data' \
--header 'Authorization: Bearer your_access_token' \
--data '{
"query": "Get user info"
}'
Conclusion
Understanding the ‘404 Not Found’ error in NGINX is essential for maintaining a healthy website and ensuring good SEO practices. With the right strategies—including creating customized responses, regularly monitoring site logs, implementing proper redirects, and utilizing tools like AI Gateway and Oauth 2.0—you can mitigate the negative impacts of this common HTTP status code.
By focusing on user experience and actively managing potential pitfalls, you can enhance your website’s performance and maintain a strong SEO presence in the vast digital landscape.
