I taking over managing a Magento CE V 126.96.36.199 shop and still finding my way around it. When a products name is changed, the existing links from google are giving 404's for the url's with the old name instead of redirecting to the new page and getting a 301.
To be more clear, let's say google has this page listed:
http://my site .com/blue-widget-290c-widgets.html
and I change the products name so the url becomes
http://my site .com/red-widget-290c-widgets.html
Before the name change, a link in google would find the page. After the change a 404 page is shown.
I know I can manually add the redirect in the URL Rewrite Maintenance section and that does work but I'm wondering if that is how Magento works or if I am missing something? Is there a known fix for this or maybe some setting I have to change? Or do I need to enter such changes in manually each time?
