SITUATION: I run a site that has published all its pages through a shopping cart publishing system that has, up to now, made all my URLs SEO-unfriendly, reading like this: "index.asp?PageAction=VIEWCATS&Category=127" Now the software will allow me to swicth the URLs to clean, SEO-friendly names like "my-product.html"
PROBLEM: When I switch the URLs, I will of course mess up a lot of inbound links from other sites that already point to the messy "index.asp?PageAction=VIEWCATS&Category=127".
QUESTION: What do I need to do to make the switch and keep the links Ive built? I need to make the previous "index.asp?PageAction=VIEWCATS&Category=127" page redirect to the new clean URL page, right? Does this involve "301 redirects"?
