I use php/mySQL to build the pages. The content that changes is typically about 90% of the page. I have no complaints about getting indexed, Google's been pretty thorough and Bing is catching up (since I started using media.net ads). I've used sitemaps for a couple of years with G. I don't have much complaints about rank, either, most of the sites above me are established and well known, although I don't feel about half of them have much to do with the keywords searched. I'll earn a higher rank in time.
