If you own a website, fixing a 403 Forbidden error is essential to guarantee an optimal and secure user experience. It's one of our SEO tips, so let's take a look together at what causes this error and how to fix it effectively.
What is a 403 Forbidden error?
Definition and understanding of the 403 error
The 403 Forbidden error is an HTTP status code indicating that the web server has received the request but refuses to process it due to a lack of permissions or authorizations. This means that even though the request is understood, access to the requested resource cannot be granted to the user.
Unlike the 401 error, which is due to authentication not having taken place, the 403 error occurs even when the user is authenticated but does not have the required permissions to access the resource.
How does the 403 Forbidden error appear?
Encountering a 403 Forbidden error can manifest in different ways in your browser.
The 403 error can appear in various forms in a web browser, indicating that the browser correctly understood the request but lacks the necessary permissions to access the requested resource.
- Explicit error messages: messages such as "Forbidden – You don't have permission to access / on this server", "403 – Forbidden: Access is denied", or "Error 403 – Forbidden" may appear.
- Access denied: a message indicating that access to the page or resource is denied may appear, such as "You are not authorized to view this page" or "It appears you don't have permission to access this page".
- Navigation issues: the error may occur when attempting to access certain pages or directories, especially if they are secured with strict protective measures.
Common causes of the 403 error and how to identify them
Incorrect file and directory permissions
As noted on this SEO-focused site, a common cause of the 403 Forbidden error is related to improper file and directory permissions. Overly restrictive permissions can prevent the web server from providing access to the requested resources.
For example, permissions that block access for everyone, including those who should have it, would trigger a 403 error. It's therefore essential to ensure that permissions are correctly configured to allow access for legitimate users. Sometimes, generating a new .htaccess file can also resolve permission issues without having to directly modify the existing file.
Web server configuration issues
A misconfigured web server can also be at the root of 403 errors. If the server is set to block access to certain resources based on IP address or geographic location, this can result in a 403 error. Security measures, such as protection against brute force attacks, can also generate these types of errors. Additionally, web server configuration issues can lead to an HTTP 403 error, preventing access to certain resources on a website.
.htaccess configuration errors
The ".htaccess" file is essential for configuring your web server. Errors in this file can be responsible for 403 errors. It's important to review this file to ensure it doesn't contain any incorrect or corrupted directives that might be restricting access to resources.
Reviewing and correcting errors in the .htaccess file is one solution for resolving the 403 error.
Hotlink protection issues
Hotlink protection, which is designed to prevent other sites from directly linking to your resources (such as images), can also lead to 403 errors. A misconfigured hotlink protection setting can block access to resources even for authorized users. Properly configuring hotlink protection is essential to avoid these types of errors. Misconfigured hotlink protection can also prevent access to certain pages on your website, affecting the user experience and the site's overall functionality.
What are the steps to fix a 403 error?
Checking and correcting file permissions
File and directory permissions are essential for accessing resources on a website, so it's necessary to check and adjust the permissions of the affected files and directories.
Here are the steps to follow:
- Check the permissions: In your ".htaccess" file, make sure files have permissions set to 644 (read and write for the owner, read-only for others) and that directories are set to 755 (read, write, and execute for the owner, read and execute for others).
- Use your CMS tool: In a CMS like WordPress, it's possible to modify access permissions, which can be done easily from your website's back office.
Reviewing and repairing .htaccess modifications
The .htaccess file plays an essential role in server configuration and can be the cause of 403 Forbidden errors if its content contains errors.
- Check the file contents: Open the .htaccess file to look for any incorrect redirect rules, access restrictions, or hotlink protection configurations.
- Restore a previous version: If recent changes were made, try reverting to an earlier version that was working. As a last resort, temporarily delete the file to check whether the 403 error is resolved.
Fixing CDN configuration issues
If your website uses a content delivery network (CDN), it may display a 403 Forbidden error due to issues such as file permissions, IP blocking, or incorrect .htaccess rules. If this happens, simply follow these 2 steps.
- Temporarily disable the CDN: This lets you check whether the CDN is the source of the problem.
- Check the CDN configuration: Make sure the CDN configuration is correct and is not blocking access to your site's resources. Consult your CDN provider's documentation for more details.
Identifying and resolving hotlink protection issues
Misconfigured hotlink protection can restrict access and generate a 403 Forbidden error.
- Check the hotlink protection rules: Review the rules in your ".htaccess" file or your hosting control panel to make sure they are not blocking access.
- Adjust the hotlink protection rules: Modify them to allow access to the necessary resources, or temporarily disable hotlink protection to test whether this resolves the problem.
The impact of 403 errors on your website's SEO
403 errors can have a significant impact on your website's SEO. When search engines like Google encounter a 403 error on your site, they may interpret it as a sign that the page or content is inaccessible. As a result, these pages will not be indexed, which can lead to a drop in your search rankings and a decrease in traffic to your site.
In addition, 403 errors can affect how users perceive your site. If visitors frequently encounter 403 errors when trying to access your site, they may conclude that your site is poorly maintained or unreliable, prompting them to look for alternatives.
It's therefore crucial to resolve 403 errors quickly to avoid any negative impact on your SEO and online reputation.

Tips for maintaining good practices:
- Regularly review permissions: Perform periodic checks to ensure they align with your security and access requirements.
- Use tools to find your 403 errors: Screaming Frog is a crawling tool that lets you list the HTTP codes for all your pages. This makes it very easy to compile all your 403 errors if your website has any.
