As you may know, most of the popular search engines -- for various reasons -- do not index pages that have querystring parameters. So, what site owners must resort to in order to get into the search engines is to make static copies of their dynamic data.
While you can do this yourself manually (e.g. write an admin interface that uses FileSystemObject to re-write HTML files when data changes), there are ISAPI filters out there that will help you index with the search engines and still keep all of your content fresh. Here are a few that I have come across:
