How to Fix 404 Errors on Your WordPress Site (2026)
A visitor clicks a link to your site and lands on a blank page that says “not found.” That is a 404 error, and if it happens often enough, it quietly drains traffic, wastes the SEO value of old backlinks, and frustrates the people you worked hard to attract. This guide covers why 404 errors happen on WordPress sites and exactly how to find and fix them.
What Causes 404 Errors on a WordPress Site?
Most 404 errors trace back to a handful of common causes: you deleted or renamed a page without redirecting the old URL, you changed your permalink structure in Settings, you migrated to a new domain or host and some links were not carried over correctly, or an external site is linking to a URL that no longer exists on your side. Broken internal links inside your own content, left behind after editing an old post, are another frequent source that many site owners never notice.
Search engines treat frequent 404 errors as a signal of poor site maintenance, and every backlink pointing at a dead page is lost ranking value you already earned. Fixing these issues is usually quick once you know where to look.
| Cause | Typical fix |
|---|---|
| Deleted or renamed page | Add a 301 redirect from the old URL to the new one |
| Changed permalink structure | Revert the setting, or bulk-redirect the old URL pattern |
| Site migration | Compare an old sitemap against the new site and redirect gaps |
| Broken internal link | Edit the post and point the link at the correct URL |
| Typo in a URL | Correct the link or redirect the mistyped path |
How to Find 404 Errors on Your Site
Start with Google Search Console, which lists pages Google has tried to crawl and could not find under Indexing > Pages, filtered to “Not found (404).” This shows you exactly which URLs search engines are hitting, which matters more than random pages that never had traffic to begin with. A broken-link checker plugin can also crawl your live site and flag internal links pointing at dead pages, which catches issues Search Console will not show you until much later.
For a faster manual check, look through your site analytics for pages with unusually high bounce rates and short time-on-page, a common fingerprint of a visitor landing on a broken page and leaving immediately. Combining both an automated crawl and a look at real visitor behavior usually surfaces the most damaging 404 errors first.
How to Fix 404 Errors With Redirects
The standard fix is a 301 redirect, a permanent instruction that sends both visitors and search engines from the old broken URL to a working one. Most SEO plugins, including Rank Math, include a redirections module where you paste the old path and the new destination, no code editing required. Keep redirects targeted: send an old blog post to its closest living replacement, not just your homepage, since a homepage catch-all redirect tends to hurt user experience and can dilute the SEO value you were trying to preserve.
If a page is genuinely gone with no replacement, a well-designed custom 404 page still helps, include your site search box, a link back to the homepage, and links to a few popular guides so visitors are not stuck at a dead end. That does not fix the underlying 404 errors search engines see, but it keeps human visitors from bouncing immediately.
Preventing Future 404 Errors
Before deleting or renaming any published page, get in the habit of adding a redirect first, it takes thirty seconds and prevents a slow bleed of broken links later. When migrating hosts or domains, export a full list of your existing URLs beforehand and check every one against the new site once the move is complete. Reliable hosting also plays a quiet role here: a host with frequent downtime or a rushed manual migration is far more likely to leave orphaned URLs behind than one with a smooth, supported migration process.
Recap: 404 errors happen when a URL a visitor or search engine expects no longer exists, most often after deleting a page, changing permalinks, or migrating a site. Find them with Google Search Console and a broken-link checker, fix the important ones with targeted 301 redirects, and build the habit of redirecting before you delete to stop future 404 errors before they start.
Want hosting that keeps broken links to a minimum?
Hostinger includes free SSL, daily backups on higher plans, and one-click WordPress installs, so migrations and redesigns are less likely to leave behind dead links in the first place.
404 Errors vs. Soft 404s
A true 404 error returns the correct HTTP status code, so search engines know immediately that the page is gone. A soft 404 is trickier: the page loads with a normal 200 OK status, but the content is empty, thin, or says “page not found” in plain text without the matching status code. According to Google official documentation on HTTP and network errors, soft 404s can be worse for SEO than real ones because search engines waste time trying to rank a page that offers nothing useful. Check your theme 404 template to make sure it actually returns a 404 status header, not just 404-looking text.
Tools and Plugins That Help
Beyond the Rank Math built-in redirections module, dedicated redirect-manager plugins log every 404 hit automatically, so you can see which broken URLs real visitors are actually landing on rather than guessing. Pair that with the crawl reports inside Google Search Console and a periodic look at your essential WordPress plugins list to keep a lightweight, well-maintained stack that does not introduce new broken links every time you update something. If you are still choosing a host, review our guide to how to choose web hosting, a stable host with good uptime reduces a whole category of accidental downtime-driven 404 errors.
Frequently Asked Questions
Do 404 errors hurt my SEO rankings? A few isolated 404 errors are normal and will not hurt you, but a large or growing number, especially on pages with existing backlinks, can waste crawl budget and lose ranking value over time.
What is the difference between a 404 and a 301 redirect? A 404 tells visitors and search engines the page does not exist. A 301 redirect permanently sends them to a different, working URL instead, preserving most of the original page SEO value.
How do I find 404 errors without a plugin? Check Google Search Console under Indexing > Pages for “Not found (404)” entries, which lists real URLs search engines have tried and failed to crawl.
Should I redirect every 404 error to my homepage? No, redirect each broken URL to the closest matching live page instead. Blanket homepage redirects create a poor user experience and can be flagged as a soft 404 by search engines.
Can a custom 404 page fix the problem? A custom 404 page improves the experience for visitors who land there, but it does not remove the 404 status itself, you still need a proper redirect for pages with real traffic or backlinks.
How often should I check for 404 errors? A quarterly check is enough for most small sites, though you should always run a check immediately after any major redesign, plugin change, or migration.
