Using 301 redirects in Magento indicates that a page has moved permanently. This practice is often used after a site migration, most importantly to avoid the irritating 404 page not found errors.
Aside from being frustrating to the visitor, losing valuable search results and old links pointing to pages that have new URLs is very costly and detrimental for your e-commerce store.
How to Create 301 Redirects in Magento:
1. Log in to the Magento Admin Panel
2. Find “Catalog” in the top navigation, hover over it for the drop box, click on “URL Rewrite Management.”
3. Right under the top navigation, on the upper right hand side, there should be an orange button that says “Add URL Rewrite.” Click on it.
4. Beside “Create URL Rewrite,” find “custom” in the drop-down menu.
Fill out the following URL Rewrite Information form.
For the ID Path and the Request Path fields, insert your old URL:
For the Target Path, add your new URL:
Lastly, for Redirect, choose: “Permanent (301)”
The Description field is meant for notes to your own team if you want to document when these URL rewrites in Magento took place and why.
