Hi. For three years we have been using an asp-based shopping cart called StoreFront 5.0. All of our product detail pages end in ".asp". We are now shopping around for a robust shopping cart solution that incorporates all of our existing features (customer reviews, customer points program, gift certificates, etc) in addition to customizable back-end reporting and inventory managment.
My question is this: Given that we have good Google rankings for our product-specific pages, will I lose those once my new product pages change address? For instance, I currently have www.mysite.com/detail.asp?product=1000 for product 1000. But when it changes to some other type of page (hence URL) like www.mysite.com/product.aspx?product=1000 (I have no idea how asp.net works, so the address might be totally different), or--better yet--http://www.mysite.com/detail/1000.htm, will I lose the original .asp detail page rankings?
Also, does anyone want to recommend a Google-friendly shopping cart?
