If you have been using the internet for some time now, you must have come across the phrase “Page not found”. It is an error page technically known as “404”. The reason for this error is that every time a user tries to reach a page for which a website cannot load or that a website’s link is broken, a “404” is generated and displays a message that says “Page not found” to the user.
Each website handles this error in a unique fashion, but the idea behind all of them is the same. Moreover, the font and page style may vary from site to site.
This article will help you in handling 404s on your WordPress website. The following points will be covered in this post:
- What is a 404 and how does it happen
- How WordPress deals with a 404
- How you can design a good 404 page
- How to keep a user from leaving your website in case of a 404
What is a 404 error?
The “404” or “page not found” error message is basically the response of HTTP (Hypertext Transfer Protocol) in a computer network. While communicating with a server over an HTTP protocol, a server always serves a website in order to show data on the browser.
So in case of an error, the server is there to serve the error so that the user knows there is some issue. The first “4” indicates a user error, such as spelling mistakes in the URL, while “04” explains how the actual error occurred.
Why WordPress Websites Need a 404?
WordPress is one of the most popular and easy-to-use tools for web development. People nowadays are using WordPress to create blogs, websites, and run their businesses. WordPress makes it very easy to put URL onto a site and change the permalink structure for SEO or any other purposes.
Suppose you have successfully created a WordPress website, and you are about to launch it over the internet. Having said that, you do not know that there is a page link in your site which was supposed to be “http://www.yourdomain.com/gallery”, but you somehow put it as “http://www.yourdomain.com/galery”, which is wrong. Due to this error, your page will not show up whenever a user clicks on that page.
So basically you have a broken link on your website for that specific page. This is where an error message should appear in order to make the user understand that there is something wrong.
How Does WordPress Handle 404s?
Whenever a user clicks on a page that does not exist or its link is broken, WordPress checks for two files in the system:
If the theme being used in the website contains a “404.php” file, WordPress will load that page and show the error to the user. But if that page is not found, then WordPress will look up the “index.php” file, and take the default action for a page not found or a broken link.
How To Design a 404 Page?
Most WordPress themes contain a 404.php file, which is usually found in “wp-content/themes/active-theme”. You can modify that page in order to make it attractive so that the user doesn’t bounce off to another website.
You need to consider the following scenarios before creating a 404 page:
- Where the 404 is coming from?
- How to fix the error (broken links, misspelled URLs, etc.), which is directing the user to a dead-end?
- How to keep the visitor hooked on to your site instead of bouncing to another?
How to Repair the Broken Links?
There are two ways a user might end up with a 404 error when visiting your website:
- 404 due to following an internal link on your site
- 404 by following an external link from another website to your site
You need to check each of your website’s URLs to make sure that every page is working perfectly. If your website has more than 50 links, it will take you many hours to check each URL and pinpoint the one with the problem. However, there are different tools available in the market, which you can use in order to check whether there are any broken links on your website. By using such tools, you can easily find out the issues on your website and fix them.
