What is a 404 page and why does it matter?
A 404 page is an error page that appears when a user tries to access an address (URL) that does not exist within your website. In other words, the server cannot find the requested resource.
This can occur for a variety of reasons:
🔹 User mistyped the URL.
🔹 The content was deleted or moved.
🔹 There is a broken link on another page (internal or external).
🔹 An incorrect URL was used in social networks or advertising campaigns.
Although this error is very common, what many people don't realize is that a poorly managed 404 page can seriously affect the user experience.
When a person arrives at a generic 404 page (like the one that comes by default in many WordPress themes), they are usually met with a simple message like “Page not found”. If there is no clear way to return to the site, explore useful content or contact the administrator, they will most likely leave the site immediately.
This causes several problems:
📉 Increased bounce rate.
⏳ Reduction of time spent on site.
❌ Lower number of page views.
🔍 Negative impact on SEO positioning.
Google, and other search engines, value user experience. If your site has a lot of 404 error exits, it can be interpreted as a sign of poor navigation or broken content, which affects your visibility in search results.
On the other hand, a well-designed 404 page can become a strategic opportunity: you can guide the visitor to your best articles, best-selling products, special offers or even invite them to subscribe to your site.

Method 2: edit your 404 page with the full site editor (themes with blocks)

If you use a Full Site Editing (FSE) compatible theme, you can edit the 404 error template directly from the WordPress dashboard, without installing additional plugins.
This method takes advantage of the new capabilities of block-based themes, introduced as of WordPress 5.9, and is ideal for those who want a more lightweight solution, without relying on external visual builders.
How to know if your theme is compatible with the full site editor?
You can check it by going to Appearance » Editor. If you see the full site block editor, your theme is compatible. Some popular examples are:
- Twenty Twenty-Two
- Twenty Twenty-Three
- Blockbase
- Neve FSE
- Kadence Blocks Theme (FSE mode)
Steps to customize the 404 page with the full site editor

Appearance » Editorfrom the WordPress dashboard. - In the left sidebar, click on “Templates”.

- Latest blog entries
- Customized text explaining the error
- Call-to-action button, to your store, a contact page or your most popular items
- List of categories or tags for easy navigation

🔧 No additional plugins are required.
🧩 Fully integrated with the WordPress block system.
💡 Ideal for sites that use a modern theme and want performance
🔄 Allows you to edit other global templates such as header, footer, blog pages, etc.
🎯 Tip: If you sell products or have featured content, use the 404 template to direct the user to those items with attractive buttons or visual blocks.
Limits of this method
Although the full site editor is powerful, it also has some limitations:
- Not all themes support it
- The design options are more basic compared to plugins such as SeedProd
- Some features, such as displaying WooCommerce products or inserting advanced shortcodes, may require additional plugins or blocks.
So, if you are looking for more visual freedom or specific integrations, we recommend using the Method 1 with SeedProd.
What useful blocks can you use on the 404 page?
Here are some practical examples that you can easily add:
Text block: to explain that the content was not found.
📰 Block of recent entries: to invite further browsing
🧭 Custom menu: with useful links or categories.
📦 WooCommerce blocks: as featured products, if you have a store.
🛎️ Contact form: for users to notify you of broken links
You can combine these blocks and group them with columns or sections, to achieve a clearer and more orderly design.
How to save and publish your new 404 page
Once you have finished customizing the template:
- Click the “Save” button (in the upper right corner).
- Confirm that you want to apply the changes to the 404 template.
- You're done! Your customized 404 page is now active.
Now you can test it by adding
/404at the end of your domain (e.g:tusitio.com/404) to see how it is displayed to visitors.
When to redirect a 404 page

It is not always necessary to redirect a 404. In fact, if it is well designed, it can keep the visitor on your site.
However, you may consider redirecting in these cases:
- The content has been removed and there is no logical replacement.
- You are getting a lot of hits to that URL
- You want to preserve the SEO value of old backlinks
To redirect in a simple way, we recommend using All in One SEO, which has a 404 error logging system and friendly redirects.

- Display a superpack of popular plugins
- Invite to subscribe to the site for more benefits
You can include buttons with calls to action such as:
🔹 “Discover our best-selling plugins.”
