Ways to Resolve the 404 Error Page

So, how do you fix an Error 404? Start by:

1. Check the URL

The first step in resolving a 404 error is verifying that you have entered the correct URL. Sometimes, a simple typo or mistake in the URL can cause a 404 error.

2. Clear Your Browser Cache

Clearing your browser cache can help resolve 404 errors by forcing the browser to fetch the latest version of the webpage from the server instead of using a cached version. Caching allows web browsers to store frequently accessed web resources, such as images and scripts, locally on a user’s computer.

However, if a website updates its content or URLs, the cached version may become outdated, resulting in a 404 error.

3. Check the Server

Checking the server cache can be a way to solve the error code, so identify and resolve issues with cached web resources on the server side. Server caching is a technique that allows frequently accessed web resources to be stored on the server itself rather than being regenerated each time they are requested. However, if the cached resource is outdated or corrupted, it can lead to a 404 error.

Checking the server cache involves examining the configuration and settings to ensure the resources are up-to-date and properly cached. If any issues are found, you can address them by clearing the server cache or adjusting the cache settings, which can help resolve the 404 error.

4. Check for Broken Links

Checking for broken links can help solve 404 errors by identifying and correcting links that no longer work or point to non-existent web pages. Broken links can occur when a webpage is moved, renamed, or deleted or when a website changes its domain name or URL structure. By scanning for broken links, website owners and administrators can identify the links causing the 404 errors and update them with the correct URL or redirect them to a relevant page.

This can help ensure that visitors to the website can access the desired content without encountering 404 errors. Several Google webmaster tools are available that can automatically scan for broken links on a website, making the process quicker and more efficient.

5. Use a Search Engine

Using a search engine can be a way to solve 404 errors by finding the correct URL or alternative resources for the desired content. When encountering a 404 error, users can try searching for the content using a search engine, such as Google or Bing. Search engines can help identify the correct URL or provide alternative links to related content.

In cases where the user is uncertain about the correct URL or when the original page has been deleted or relocated, this feature becomes particularly beneficial.

6. Customize the 404 Error Page

Using custom error pages can be a way to solve 404 errors by providing users with helpful information and alternative resources when they encounter a missing or unavailable page. By default, when a server returns a 404 error, the user is presented with a generic error page that may not provide useful information or guidance.

The custom page can include information about why the page is unavailable, suggestions for alternative pages or resources, and links to other parts of the website. The custom 404 error page can help reduce frustration and improve the overall user experience by providing users with helpful information and guidance.

To lessen the impact of not found errors on SEO, website owners should regularly monitor their website for broken links and 404 errors and implement redirects where necessary to ensure that users and search engines can access the correct content.
