The 5 Most Common HTTP Errors According to Google Statistics

Sometimes when visiting a website, HTTP error messages may pop up. These messages from the web server inform visitors that an error has occurred at that moment. Sometimes it's the visitor's fault, but most of the time, the error originates from the website.

Each type of error is caused by a specific HTTP error code. For example, if a user tries to access a page on a website that does not exist, the common 404 error occurs.

Now you might be wondering, which are the most common HTTP errors encountered when visiting websites? This is the question we aim to answer in this article.

Using Google Insights for Search (a tool that calculates the popularity of search terms), we examined all existing HTTP error codes and compared them with each other. Below is the ranking of the most frequently occurring HTTP error codes found during the survey:
