Why use 301 redirects?

There are several reasons why you might need to use 301 redirects on your website:

  • Deleting a page : If you delete a page or pages from your website, you can redirect users to a similar page or to another relevant resource using a 301 redirect.

How do I set up 301 redirects?

There are various ways of implementing 301 redirects on a website, depending on the technology used and the level of access you have. Here are a few common methods:

Modifying the .htaccess file

For websites hosted on an Apache server, 301 redirects can be easily managed by modifying the .htaccess. This method requires FTP access to the server where your website is located. To create a 301 redirect, simply add the following code to the :

Redirect 301 /old-page.html http://exemple.com/nouvelle-page.html

Replace /old-page.html by the obsolete part of the URL and http://exemple.com/nouvelle-page.html with the full address of the new page. You can add as many 301 redirects as you need by creating a new line for each URL.

Use of CMS plugins or extensions

If your website is based on a content management system (CMS) such that WordPress, Joomla or DrupalYou can use dedicated plugins or extensions to manage 301 redirects. These solutions make the process much easier by simplifying the addition and modification of redirects directly from the CMS dashboard.

Here are a few examples of popular plugins for managing 301 redirects:

    • WordPress : Redirection, Simple 301 Redirects
    • Joomla : ReDJ, Redirect-On-Login
    • Drupal : Redirect, Global Redirect

Modifying server files for Nginx and Microsoft IIS

For sites hosted on Nginx or Microsoft Internet Information Services (IIS) servers, the changes required to set up 301 redirects generally need to be made in the server configuration files or via the administration interface. We recommend that you consult the official documentation or ask your web host for help with instructions specific to your environment.

Common mistakes and pitfalls to avoid when using 301 redirects

Here are some common errors and tips to ensure that your 301 redirects work properly:

  • Avoid chain redirects: Setting up several successive redirects for the same URL can slow down page load times and harm your SEO. Make sure that each redirect leads directly to the new target URL without any intermediate steps.

  • Update internal links: When you set up a 301 redirect, don't forget to update all the internal links pointing to the old URL in order to avoid unnecessary redirects and improve the user experience.

  • Check redirects regularly: We recommend that you regularly check your 301 redirects to detect any problems or errors. You can use online tools such as Screaming Frog or Ahrefs Site Audit to identify broken or faulty redirects.

  • Pay attention to URL parameters : If your site uses URL parameters to offer different versions of content (e.g. sort, filters, pagination), make sure that your 301 redirects take these variations into account and do not interfere with the normal operation of your site.

In short, 301 redirects are an essential part of ensuring a good user experience and maintaining your website's SEO quality.

By managing your redirects correctly, you can avoid common errors and ensure that your visitors and search engines access the most up-to-date and relevant version of your content.
