404 Not Found Error: Causes, Fixes, and SEO Best Practices

The Frustration of a 404 Error

You’re browsing a website, clicking on a link that promises valuable information—and then it happens. Then you’re greeted with a cold, sterile “404 Not Found” message. It’s frustrating. Lost, aren’t you? The content you were expecting is gone, and more often than not, you hit the back button and leave.

Now imagine this happening to the visitors on your website. Every time someone lands on a broken link or deleted page, there’s a high chance they’ll bounce off without taking action. That’s a lost opportunity, both for engagement and conversions. Worse, too many 404 errors can damage your credibility and weaken your site’s SEO indirectly.

In this comprehensive guide, we’ll break down everything you need to know about 404 errors—what causes them, how they impact SEO, how to fix them, and how to turn them into positive engagement tools that support your SEO and branding strategies.

What is a 404 Not Found Error?

404 Error Website

A 404 Not Found error occurs when a server cannot find the requested resource. In simpler terms, the page that a user is trying to access is missing or doesn’t exist on the website.

There are several common causes for a 404 error:

1. Expired Domain or Hosting Issues

If a website’s domain has expired or if the hosting service is down, all pages will return a 404 error. Sometimes, even DNS configuration issues can cause this temporarily.

2. Typographical Errors in the URL

Even a small typo in a URL can lead to a non-existent page. For instance, typing “/bloog” instead of “/blog” will result in a 404.

3. Deleted or Moved Pages Without Redirects

When website owners restructure or redesign their websites, pages may get moved or deleted. If they fail to set up redirects for the old URLs, users clicking on old links will land on a 404 page.

4. Broken Internal or External Links

Links that point to pages that no longer exist, whether internal (within the site) or external (from another site), will result in 404s.

5. Plugin or Theme Conflicts

In WordPress and other CMS platforms, certain plugin or theme updates might inadvertently break page URLs, leading to 404 errors.

How 404 Errors Affect SEO

Google has made it clear: 404 errors do not directly penalize your website. However, the indirect consequences of too many 404 errors can significantly hurt your SEO and overall site performance.

Here’s how:

  • Poor User Experience (UX): Visitors who land on a 404 page may get frustrated and leave immediately. This increases your bounce rate—a signal Google might interpret as a poor user experience.
  • Lost Traffic & Conversions: A user who doesn’t find what they’re looking for is unlikely to explore further or return later.
  • Crawl Budget Waste: Googlebot has a limited crawl budget per site. Wasting that budget on 404 pages means fewer important pages are being crawled and indexed.
  • Backlink Loss: If a high-authority website links to a page that now returns a 404 error, the SEO value (link juice) from that backlink is lost unless it’s redirected properly.

How Google Treats 404 Errors

Google is smart—it understands that 404 errors are sometimes unavoidable. However, if your website has too many of them or critical pages start returning 404s, that’s a red flag.

Impacts on indexing and rankings may include:

  • Pages being dropped from the index
  • Delayed indexing of new content
  • Lower domain trust and authority signals

This is why it’s crucial to monitor, manage, and fix 404s as soon as they arise.

How to Fix 404 Errors on Your Website

Now that we know how harmful they can be, let’s look at how to fix 404 errors systematically.

🔎 Step 1: Identify Broken Links

The first step is identifying where the problems are. Use the following tools:

  • Google Search Console: Navigate to Index > Pages > Not Indexed to see a list of 404 errors Google has found.
  • Screaming Frog SEO Spider: Crawl your site and find 404s quickly.
  • Ahrefs / SEMrush: These tools provide in-depth broken link reports, especially useful for backlinks.
  • Analytics: Use Google Analytics to review bounce rates and exit rates, which can help identify potential problem areas on your website.

🔄 Step 2: Set Up Proper Redirects

Once you’ve identified the broken pages, fix them by setting up 301 redirects (for permanent page changes) or 302 redirects (temporary).

  • Use tools like Redirection (WordPress plugin) or configure redirects via .htaccess or your hosting control panel.
  • If a relevant new page doesn’t exist, redirect to a related category, blog, or your homepage.

✍ Step 3: Update Internal & External Links

Don’t just rely on redirects—clean up broken URLs too.

  • Update internal links in menus, footers, blog posts, and product pages.
  • Reach out to websites that have backlinks to the broken page and request an update (especially if the link comes from a high-authority site).

🛠 Step 4: Restore Deleted Pages (if needed)

Sometimes the best fix is to bring back valuable content:

  • Use the Wayback Machine (archive.org) to retrieve the deleted content.
  • Check if the page had good traffic or backlinks—reviving it can instantly recover lost SEO value.

How to Keep Visitors Engaged on a 404 Page

Even if a user lands on a 404 page, that doesn’t have to be the end of their journey. A smart, user-friendly 404 page can keep them on your site longer.

What Makes a Great 404 Page?

  • Friendly Message: Use approachable language like “Oops! We couldn’t find that page.”
  • Navigation Options: Include links to the homepage, blog, or product categories.
  • Search Bar: Help users search for what they were looking for.
  • Brand Personality: Use humor, visual design, and tone to match your brand voice.
  • Call to Action: Suggest related articles or product recommendations.
  • Report a Problem: Allow users to inform you about broken links.

Examples of Creative 404 Pages

  • Airbnb: Uses a fun animation of a lost traveler.
  • LEGO: Features a broken LEGO figure with a witty message.
  • GitHub: Offers a Star Wars-themed error page.
  • Amazon: Uses a helpful search bar and popular categories.
