Yes, Google indexes dynamically generated webpages, including .asp pages, .php pages, and pages with question marks in their URLs. However, these pages can cause problems for our crawler and may be ignored. If you’re concerned that your dynamically generated pages are being ignored, you may want to consider creating static copies of these pages for our crawler. If you do this, please be sure to include a robots.txt file that disallows the dynamic pages in order to ensure that these pages aren’t seen as having duplicate content. In addition, you might consider creating and submitting a detailed Sitemap of your pages using the Sitemaps component of our webmaster tools. Our webmaster tools are an easy way for you to submit all your URLs to the Google index and get detailed reports about the visibility of your pages on Google. You can automatically keep us informed of all of your current pages and of any updates you make to those pages. Please note that submitting a Sitemap doesn’t guarantee that all pages of your site will be crawled or included in our search results.
