Hi, I have been building static page copies for my dynamic pages and i see higher rankings for my pages in google. I think most webmasters are missing it out. Not every search engine spider crawls dynamic pages as well as static pages. Google's Webmaster Guidelines clearly state that to "make your site easily accessible...Consider creating static copies of dynamic pages." I use a great software which builds me static pages in a jiffy. PM me if you would like to know more about that soft.
