Once in awhile you have to move a Joomla site to a new domain, or a page to a different link or category. When that happens you don’t want lose all of the traffic that you’ve been getting at the old domain. This is where a good old-fashioned 301 redirect comes in handy.
Redirects, or URL forwarding, can be very useful for a number of reasons. When enabled, a 301 redirect can make a site or page accessible through many different URLs. A 301 redirect, for instance, will permanently redirect a URL to a particular site all while maintaining search engine rankings. It's a safe way to perform a redirect and it's easy to create using the core Joomla Redirect component.
This tutorial explains how to create a Redirect using the core Joomla Redirect Manager.
Enabling the Redirect Plug-in
By default, your Redirect Plug-in should be enabled. If you want to double check, log into the back end of your site and go to the Plug-in Manager.
Find the "System - Redirect" Plug-in and be sure it is "Enabled". If it isn t, simply open it, enable it and save it.
Creating a New Redirect
use redirect menu link
First, log in to the Administration area (the back end) of your site and go to Components > Redirect.
If it's not enabled, read the instructions above to enable it.
Click on the "New" button in the toolbar to create a new Redirect
In the "Source URL" field, enter the old URL. In the "Destination URL" field, enter the new URL.
Of course, each URL must be valid in order for the Redirect to work, so be sure you check the URL for accuracy.
You should also be sure that the redirect you are creating is "Enabled" before clicking on the "Save & Close" button in the toolbar.
After saving & closing, you will receive a green message indicating that you successfully saved your Redirect.
Any Redirect you create will appear in a list in the Redirect Manager so you can come back in the future and edit, disable or delete the Redirect.
