I'm not sure if I am posting in the correct place so I appologise in advance.
I have a database driven catalogue site. A number of products are listed in search engines specifically google (which is good). Now when I delete a product that product can no longer be found meaning that when someone click on a link from a google the product cannot be displayed, My site handles this gracfully catching the error and displays an error page pointing the visitor in the right direction.
My question is how should I handle this situation with the googlebot and other robots?
