Error 500, also known as ‘Internal Server Error’, is a server error that can occur when browsing the web. In this article, we will discuss what error 500 is, how it affects the performance of a website and its positioning in search results. We will also outline potential causes and possible solutions to this problem.
What is an Error 500?
A 500 error is an HTTP response code that indicates that the server has encountered an unexpected problem preventing the requested web page from displaying. This error is considered a server-side error, meaning that the problem is something on the server and not on the user’s site.
Causes of error 500
There are many potential causes of error 500, but here are some of the most common:
- Errors in the configuration files: Incorrect settings in the server’s configuration files can lead to error 500.
- Permissions issues: Incorrect permissions to files and folders on the server can cause a 500 error.
- Script errors: An error in the page source code can cause a 500 error, especially if the code affects the way the server handles requests.
- Server resource limit: If the server reaches its resource limit, such as RAM or CPU, a 500 error may occur.
- Database problems: Database corruption or problems connecting to the database can lead to a 500 error.
Error 500 and SEO
Error 500 can have a negative impact on the positioning of a website in search results. Search engines, such as Google, aim to provide users with the most valuable and useful results. Pages with error 500 may be considered less valuable because they are unable to deliver the expected content to users.
If the 500 error occurs only occasionally, the impact on SEO may be minor. However, long-term problems with a 500 error can lead to a reduction in the page’s position in search results. Therefore, it is important to regularly monitor your site and resolve error 500 issues to keep your site high in search results.
How do you solve a 500 error problem?
Here are some steps you can take to resolve an error 500 problem:
- Check your configuration files: Make sure your server’s configuration files, such as .htaccess or php.ini, are set correctly and do not contain errors.
- Check permissions: Check the permissions of files and folders on the server to ensure they are correct and in line with the server’s requirements.
- Check for errors in scripts: Review the source code of your site to find and fix any errors that may be causing the 500 error.
- Increase server resources: If the 500 error is caused by a limitation of server resources, consider increasing available resources such as RAM or CPU.
- Fix database issues: Check the state of your database and ensure that the connection to it is working properly. If necessary, repair damaged tables or optimise the database.
