WordPress 404 errorGetting the error code 404 on your website is a nightmare. If you’re on WordPress, figuring out how to avoid WordPress error 404 pages can be quite a challenge. By default, WordPress does have default settings which will help you deal with the dreaded 404 error, but it’s not exactly picture perfect. So how do you fix the error 404 message? More importantly, how do you prevent it from happening on any of your site’s pages?

This is the ultimate guide for WordPress Error pages. This particular guide provides answers as to why this error message happens in the first place, how you can avoid having this error message, and a lot of other information. Listed in this post are several plugins which will help in dealing with 404 errors. Once you’re through reading this post, you’ll know exactly what to do whenever you get a 404 error message.

The Causes of Error 404 Pages in WordPress

One of the main causes of 404 error message in WordPress is a change in the permalink of the posts. For example, if the website owner decides to change how the permalinks of the site’s pages are set up, they will end up with incoming links that point to a page which is no longer at that particular address. What this means for your site visitors is that instead of getting the content they were searching for, they’ll get a 404 page instead.

Another reason why you could have a 404 error message has something to do with mod_rewrite not being installed or missing in your server. If you want to use Pretty Permalinks, you need to have mod_rewrite working on your server. So in case you’re trying to use Pretty Permalinks and you end up with this error message, this is definitely the first thing you should check.

Yet another cause of having 404 pages could like in your index.php file or the search.php file. If you have an error in the code in either one of these files, it could return results with invalid addresses, or not even return results at all. If you’ve customized either your index.php or search.php file, it’s imperative that you check and make sure that they are not serving up invalid addresses, and that all of the different pages of your site are working properly. This is why it’s a good practice to make a backup of the previous version of each file before making any changes. In this way, you have a copy of the older file to roll back to in case you need it.

How Error 404 Can Damage Your Site’s Reputation

Obviously, the bounce rate on your site is the first thing that will be affected when you have the 404 error on your site’s pages. For example, if a site visitor follows a link to your site and they end up with a page that has the 404 error instead of what they were looking for, they will most likely leave and look elsewhere. It’s very unlikely that they will stay on your site and search for what they were looking for in it.

If you have a lot of 404 errors on your site’s pages, this will probably affect your search engine rankings as well. When engine spiders keep getting non-existent pages on your site, your site will get penalized for having invalid links. If only one or two pages of your site have this error message, then it isn’t going to have much of an impact. But, if the search engines can’t find half of the pages that it thinks should be there, then expect a bigger hit.

 How to prevent Error 404 for your WordPress blog

By far the best way to prevent the error 404 is to be proactive. You should have your permalinks set up from the start, instead of changing them once the content is live on the web. Spending time when you create your blog and making sure everything is in order will mean you’re unlikely to make any changes in your set up in the future.

You should also check any incoming links you have, and proactively contact any site owner who has an incorrect incoming link. A lot of site owners will be happy to fix the error if you let them know about it.  If you have old content that you want to delete from your site, stop for a moment and don’t delete. If you really have to take it down, you should create a page using the same permalink to provide information to site visitors on the content that used to be there. This is also a great opportunity to include links to other similar content that your site visitors may be interested in. You can also make use of WordPress error 404 plugins to help you prevent and deal with error 404.
