Many people don’t know the difference between 404 and 301. If you are in the Web development or SEO services field, you must have to know about this. It’s important to understand the difference between 404 and 301. Although these two codes seem like technical words. It can impact your website’s user experience and website rankings.
In this article, we’ll explain these codes and their importance.
404 – Page Not Found
404 (Page Not Found) is one of the most common errors on the internet. When a user visits a page that doesn’t exist or has been removed, the server responds with a 404 error (Page Not Found). This means it tells the user and search engines that the requested resource cannot be located. If you don’t know how to find 404 page errors, you can find it from the search console or you can also use a free third party tool like Broken link Check.
key points:
- User Experience: From a user perspective, facing a 404 error can be frustrating. It’s like hitting a dead end while visiting a website. Users may leave your site if they repeatedly visit these errors.
- SEO Impact: Search engines note 404 errors when crawling your site. While having a few 404 errors is expected, an excessive number can negatively affect your SEO. Monitoring and fixing broken links is essential to maintain a healthy website.
- Best Practice: When a page is permanently removed, it’s best to use a 301 redirect instead of a 404 error to guide users and search engines to the new location of the content. Make sure the redirect page should be relevant to that page.
301 – Moved Permanently (Redirection)
The HTTP status code 301 is a redirection status code. It indicates that the requested resource has been permanently moved to a new location. When a user or search engine encounters a 301 status code, they are automatically redirected to the new URL specified by the server.
key points:
- User Experience: From a user perspective, 301 redirects are seamless. Users are automatically taken to the new location without any effort on their part. This helps maintain a positive user experience.
- SEO Impact: Search engines interpret 301 redirects as a signal that the old URL should be replaced with the new one in their index. This passes the SEO value (such as link juice and rankings) from the old page to the new one.
- Best Practice: Use 301 redirects when you change the URL structure of your website or when you permanently move or replace content. It’s a powerful tool for maintaining SEO equity and ensuring users find the correct information.
404 vs 301: Quick Comparison Table
| Feature / Metric | 404 Error | 301 Redirect |
|---|---|---|
| Server Response | “Not Found” | “Moved Permanently” |
| User Experience | May frustrate users | Smooth redirection |
| SEO / Link Equity | Lost if many broken links | SEO value preserved |
| Use Case | Permanently removed content with no replacement | Reorganization, renaming, merging pages |
The Best Ways to Use 301 and 404
- Check for Broken Links Frequently
To identify 404s, use tools such as Broken Link Check, Screaming Frog, or Google Search Console. - 301 is always preferable to 404. If at all possible
Old URLs should be redirected to relevant, related pages; avoid sending all traffic to the homepage since this might negatively impact SEO. - Reduce the Length of Redirect Chains
Redirects should not be chained together (URL A → URL B → URL C). One straight 301 from A to C should be used. - Revise Internal Links
Make sure internal links on your website refer to the new URL rather than the old one after a redirect. - Personalised 404 Page
Make a 404 page that is easy to use, including a search box, navigation, and useful links, even if there aren’t many 404. - Track Traffic Following Modifications
After setting redirects, use analytics to make sure traffic and rankings stay consistent.
Why It Is Important for User Experience and SEO
- An excessive number of 404 damages user trust and gives the impression that your site is ignored.
- Search engines may penalise your website or decrease crawl efficiency as a result of poor reroute policies.
- When reorganising your website or combining content, using 301 correctly helps maintain ranking power.
Conclusion
Basically, a 404 error means the page you’re looking for doesn’t exist, which isn’t good for users and search engines. And with 301 redirection we can move permanently to a new page or URL, so users and search engines can find it easily. Using these codes correctly is super important for a better user experience and good search engine results.
