What Causes Error 404 Pages in WordPress?

404 pages in WordPress are most often caused by a change in the permalink structure of the site. If a site owner changes the permalink structure of their WP blog, they’re going to end up with incoming links pointing to pages that are no longer located at a particular address.

This means that the incoming visitors will be given a 404 page instead of the content they were looking for.

Other causes of 404 pages may be in the code of your index.php or search.php files. If there’s an error in the code in either file, it may return results with invalid addresses (or it may not return results at all).

If you’ve made customizations to your index.php or search.php files, it’s a good idea to check and make sure they’re not serving up invalid addresses and that all of your pages are still working. Always save a backup of the previous version of each file before making changes in case you need to roll back to an earlier version.

Another common reason for getting a 404 page has to do with mod_rewrite not being installed on your server. In order to use Pretty Permalinks, you have to have mod_rewrite working on your server. If you’re trying to use Pretty Permalinks and are getting errors, this is the first thing to check.

Potential Damages of Error 404 Pages

The most obvious damage caused by a 404 page has to do with the bounce rate on your site. If a visitor follows a link to your site and they get a 404 page rather than the content they were looking for, it’s unlikely they’ll search your site to find it. They may assume that it no longer exists and simply look elsewhere.

If your site is filled with 404 errors, it’s possible you’ll take a hit in search engine rankings, too. If search engine spiders are constantly presented with non-existent pages, they’ll penalize your site for having invalid links.

One or two 404 pages may not have much of an impact, but if half the pages the search engine thinks should be there aren’t, you’ll take a bigger hit.

How to Prevent Error 404 Pages

The best way to prevent 404 pages is to be proactive. First of all, set up your permalinks properly from the start. If you take the time when you first launch a blog to set up well-structured permalinks, it’s unlikely that you’ll need to change them in the future.

Be proactive about incoming links that aren’t correct. Send a quick note to the person who runs the site with the link and ask them to change it to the correct link. Most site owners will be more than happy to do so.

Don’t take down old content. If you have to take something down, rather than deleting it entirely, create a custom page at that address that provides some information on what used to be there, or links to other posts and pages that might be of interest to the visitor.
