Most Common Website Errors  

Broken links, unresponsive pages, broken code, slow loading, and other common website errors can damage your SEO and push your website’s rank down. Error codes come in five major categories. The starting digit is the fastest way to determine the error you’re dealing with. 

Look at the first digit 

All error codes have from 1 to 5 as the first digit. Codes starting with 5xx show your website’s backend is having an issue. A user request isn’t getting processed because the server is not responding. 

You have experienced the 404 Page Not Found error at least once. All error codes that start with “4” show the page doesn’t exist anymore. This is due to a broken URL, a new domain name, or a lack of permission to access the page.

Error codes that start with 3xx appear when the network redirects an old URL to a new one. 

The error code beginning with “2” doesn’t designate an error. If you see a 2xx on the screen, it means the server has accepted your request. 

Finally, info error codes begin with the number “1”, which you’ll usually see when the website responds too slowly to a user request.

Low loading speed is one of the most common and damaging errors. Even a one-second delay can have devastating results. GTmetrix is a tool you can use to determine why your page load speed is low. It provides insights into every page for desktop and mobile. It will also show you how your site is performing in almost two dozen global regions.

401

The 401 Unauthorized error code means a user doesn’t have the credentials to access a website. The easiest fix is often to close your browser window and reopen it with the accurate URL. If the wrong password is the reason, you can reset it. Clearing the browser cache will help if you saved the wrong credentials locally in the browser. 

400 

The 400 Bad Request error message appears when the user makes an inaccurate request and the server does not respond to it. You need to make sure you are using the right web address. Other steps you can take include clearing your browser cache via DNS Flush. 

It’s also a good idea to cut down on the file size so you don’t end up somewhere you don’t want to be. 

404 

The Page Not Found error mentioned above usually occurs when the user enters a dead or broken link. Alternatively, the server might be unresponsive to large files and load them slowly. 

The first step you should take is to check if you entered the right URL – this works to remedy most website errors. Perhaps the content you’re looking for doesn’t exist anymore. If this is the case, find the new web address and redirect the old one to it. Ensure the server on which the site is hosted runs without errors. Delete your browser cache.
