Impact of 403 Errors on SEO and User Experience

403 error

403 errors, often referred to as “Forbidden” errors, are HTTP status codes indicating that the server understands the client’s request, but the server refuses to authorize it. This can have significant implications for both SEO and user experience.


Definition of 403 Errors

A 403 error occurs when a user tries to access a web page or resource but is denied permission by the server. This could be due to various reasons, such as insufficient credentials or IP restrictions.

Importance of Website Accessibility

Website accessibility is crucial for ensuring that all users, regardless of their abilities or disabilities, can navigate and interact with a site effectively. 403 errors directly impact this accessibility, potentially alienating users and affecting their overall experience.

How Do 403 Errors Occur?

Unauthorized Access

One common cause of a 403 error is when a user attempts to access a part of the website for which they don’t have the necessary permissions. This could be a restricted admin area or a premium content section.

Permission Issues

In some cases, incorrect user permissions can lead to 403 errors. For instance, if a user is mistakenly assigned limited access, they may encounter this error when trying to reach certain pages.

Server Misconfigurations

Improper server configurations, such as incorrect file permissions or directory settings, can also trigger 403 errors. These issues often arise during website maintenance or updates.

Impact on SEO

Search Engine Crawling

When search engine bots encounter a 403 error while crawling a site, it disrupts the indexing process. This means that affected pages may not be included in search results.


Even if a page is already indexed, ongoing 403 errors can lead to de-indexing. This means the page will no longer appear in search results, even if it was previously ranking well.


If important pages on your website consistently return 403 errors, search engines may interpret this as a sign of poor quality or unreliable content. This can negatively impact your site’s overall ranking.

Effect on User Experience

Frustration and Bounce Rates

Encountering a 403 error can be frustrating for users. It disrupts their browsing experience and may lead to higher bounce rates as visitors quickly leave the site in frustration.

Trust and Credibility

Repeated 403 errors can erode trust in your website. Users may begin to question the reliability and security of your site, which can have long-lasting effects on your brand’s credibility.

User Engagement

403 errors can hinder user engagement. If visitors can’t access the content they’re looking for, they’re less likely to spend time on your site or take desired actions, such as making a purchase or filling out a form.
