Several pages in e-commerce and other functional sites are generated dynamically and have? or & sign in their dynamic URLs. These signs separate the CGI variables. While Google will crawl these pages, many other engines will not. One inconvenient solution is to develop static equivalent of the dynamic pages and have them on your site. Another way to avoid such dynamic URLs is to rewrite these URLs using a syntax that is accepted by the crawler and also understood as equivalent to the dynamic URL by the application server. The Amazon site shows dynamic URLs in such syntax. If you are using Apache webserver, you can use Apache rewrite rules to enable this conversion.
